This starts out with this thread,http://davesgarden.com/t/399153/
Thought I should put it here.
My friend Bo that I work with builds fake rocks,I am totally hooked on this process now.
Here is a picture of a pond he built,all rocks are fake.
Zany,they are made of concrete and steel,need I say more!!LOL!
I have his portfolio now so I can put up some more pics to drool over!
I am going tomorrow to help put the final touches on a small one,anyway
Here is another pond he did,some are swimming pools.
This is at my bosses house.
Love the indian head,he had some extra crete
Root, how long from beginning to end does a project like this take? Does your friend make all his own fake pebbles, stones & boulders himself? Does he do the excavation of the pond or is that outsourced to another company that has a backhoe? DETAILS, Details, I need details...!!! :~)
Shirley,it is pretty cool,he wraps them in plastic molds,like you see Hollywood use rubber masks of peoples faces,well they have all the rock cracks,grooves and oddities in the mold,after it dries,he peels the plastic,and cuts groves.
In this one you can see the pile to right,the brown is the plastic molding forms.
If you could get the name & author of the book he is using, I would love to read through it and get lots of ideas! Your friend sounds like he has perfected the art of concrete sculpting if he can make fake rocks, fossils in stone & dinosaur tracks. Totally awesome!!
I am sorry I did not reply to you Shirley.
Equilibrium,the book I was referring to was the book he brings with his pictures,to show while giving bids.I borrowed it and scanned these pictures,sorry for any confusion
That makes perfect sense. Would you ask your friend if he would be in a position to share his tips fo the trade with us over here? Thanks much.
Come to think of it, if he is in a position to explain how to make this masterpiece on a much smaller scale such as for a birdbath fountain and birdbath waterfall that would be really nice. As long as I could get a feel for the basics I might try to have a go at this. Nothing of the magnitude of what he created but a nice water feature for birds would be real nice. I have ideas in my head but never could quite figure out how to put them into use.
Hi Rootdoctor. I have seen a lot of fake rocks and I have to say that these are possibly the best finished. Please pass on my admiration. Since I do some concrete art work myself I know the difficulties and effort involved. I really like the lip of the waterfall in the first pic. For those of you interested in doing some artistic concrete projects an excellent book is "Making Concrete Garden Ornaments" by Sherri Warner Hunter. The publisher is Lark Books and you can get it on EBay. Of course you should check your local library first. This is not the typical crafts type of work.
Hi rootdoctor, I have spent hundreds of hours on the Internet researching backyard wildlife habitat. I, too, have seen a lot of rocks and your friend's mock rocks blow anything I have ever seen out of the water for a pond application. They are so well done with so much attention to detail that they look as if they could be used in habitat creation at a zoo.
Hi jessamine, there is another thread in these forums that has the best boulders I have ever seen. They are so natural in appearance jutting out from the ground that they look as if they were unearthed when the homeowners excavated their yard to landscape. You really need to look at this thread- http://davesgarden.com/forums/t/439175/
These are the most natural looking "boulders" I have ever seen. They sort of melt into their setting and if I hadn't been told they were manufactured, I would have never known.
I am absolutely in awe at what I have seen in this thread and the other thread linked above.
That wouldn't have enough height to it would it? I was thinking something more cylindrical possibly that was about 3' tall. Your 5 gallon idea would work. You just stick a hunk of metal in the bottom segment while it is forming. Then align that piece to the next piece and use a concrete drill so that you could insert the bottom up into the top. I am not making sense but I can actually picture this in my peon brain.
Hey Equilibrium: It is possible to use a section of 4 to 6 inch PVC tubing for a mold if you spray it with mold release or Pam. If you have trouble with the thing releasing you can always cut the tube in half lengthwise and tie or tape it together for a two piece mold. Use a lot of tape. Set it in a box of sand to support it til it starts to set up. Scraps of 2x6 or larger can be cobbled together for more regular shape molds. If you want to get fancy tack pieces of trim in rectangles or other patterns on the inner face of the 2x6s. You will wind up with a basrelief design but you will have to lift the sides off cause they won't slide. Will get back with some other ideas later. Have to go do some final winterizing on the pond. Jessamine
I'm so slap happy lately I'm thinking we could just stand around and toss the concrete mix at the pvc and call it a freeform base. Whadya think? We could call it a slop party. Slop it on and toss a basin on top. Works for me.
You and me too.Just add some crumpled hardware cloth to the PVC before you start tossing and you would have instant art ! Do it in front of someone and you have performance art. When I was doing ceramics I loved to "wedge" the clay. It was a perfect way to work out your stress. To wedge clay just cover a corner of the basement ((or other workspace) with plastic and grab a couple handfuls of wet clay. With as much force as you can muster, SLAM the clay against the wall, the floor (or both if you just had an argument with someone). This drives out the air bubbles in the clay. Somehow I used to wedge a lot more clay than I needed. Jessamine
You have a point there. Wouldn't be much form without the crumpled hardware cloth. Thank you so much for finally putting a name to that technique I used back in a pottery class. "Wedging"... didn't kwow there was an actual name to that act. Cool. I can't wait to share it with a friend of mine who practiced the fine art of "wedging" with me.
rootdoctor: I'm getting ready to build a pond and water garden. Rocks are very expensive here. Do you have any suggestions for me? I would love to have some of your fake rocks but don't think that is possible. Are there any companies in GA that do the same thing? Elaine
Kannapolis! How nice to meet you. Stopped there with my sister several years ago on our way back from Charlotte and had a total meltdown on our credit cards. Are you new there or an old hand? Jessamine
Um Jessamine, there's help for people who experience credit card meltdown. I'm an old hand at it and I was on my way to recovery until... until... I became acquainted with BogMan. There I was just minding my own business and out of the big black bog came BogMan who sent me my very first bog plants. The twitches and tremors subside for a while right after I get a plant. I have to use my credit card to keep the symptoms at bay. There is no other way. By the way, I'm in this thread to satiate my need for a fix. I need to make mock rock for my new bog. And then there will be a need for more plants, and then more mock rock, and then more plants, and well it's a never ending vicious cycle!
Hi Jessamine! I am both new and old - lol.. This is my DH's hometown and I have lived here 4 years before that I lived in Concord (10 min from here) for 8 years. I have been in this area since 1989. Came here for school and just never left! It's a small town near a big one which is a good mix..
I just saw this thread for the first time. Bumping it, because it's so great! I want to have our pond surrounded by rocks like this. It's just a little pond, and adding the height of a waterfall behind it would make such a great feature.
Actually some neopreme (sp?) gloves will last longer and protect better.
A young guy got some cement down his boot at work one day, (I poured concrete by the cubic yard, with a crane).
He was a real go getter, so he kept on working. Got a terrible infection.
I intend this to only be a heads-up. Not a discouragement.
There is a lot of lime in cement that could give you a burn if it was in contact with your skin too long. That would make an infection pretty easy to get if you were wearing boots. Just wash it off if you get it on you. Jessamine
How would you make a mold of a rock face? Can you buy something to spray on and remove and where can you buy it. Say, spray on a release agent and they coat it with some sort of plastic. I see it done on this thread but want to know how.
Just won this on E-bay so I can get the general Idea on how to do some of the things. Will start small and work up to the big project I want to build. A water fall to suround my stock tank I convertered to a Bio filter.

I just gotta reply to this thread again.
Thank you for posting this, it's truly a ponding inspiration.
I did some research on making your own inground swimming pools last year but never got the nerve (or money, haha) to really try it.
That one pool looks like a lagoon- the water is so nice and blue. How do you get it to stay so clear? Chlorine?
Is it painted white?
Sorry ta be a bother, just wanna learn!
You could probably get a mold making kit especially designed for faces and make a mold of your face.
Then smash it into damp sand and gently pour concrete into it the impression it left. It might work.
TARogers5 the only really advanced info I've found are expensive hands on classes that are offered. The info you are getting will give you lots of ideas and then it is mostly practice and trial and error. I haven't tried making latex molds yet. I think that is the "secret" to really elegant work like is seen in this thread. I have made a few hand formed boulders over hardware cloth forms. very labor intensive!
Ideas always tumblilng around in my head. Will try a mold but was not wanting to do any painting as I know I could not make a blob of concrete look like a rock.
What if you used a flour water mix to coat the inside of a mold and then sprikled Vermiculite on it. Would the wet cement pick it up off the mold for texture.
Cant wait to try some of this out.
I seen some one on the net a while back that was telling how to use a trowel to make the concrete look like rock protuding slabs. Should of copied it then. We will all work on this togather and share.
You bet Ted. I'm working on a project now using trois "making rocks" thread as my guide. The reason I like his method is that the concrete IS heavy like real rocks. I will start a new thread soon showing how I am using that method.
The thing about me is that I have no artistic talent at all so I am really sticking my neck out by doing this project publically. I will need all the help I can get!!
Ted in high school we made a vermiculite/plaster of paris blocks in milk cartons to have a carving medium. This was an interesting texture and vermiculite might be a possible additive.
When you live where it freezes, being aware of what will allow water to collect and freeze, cracking the cement.
It is so much fun being a kid again and not having someone tell us we cant do this or that.
Been watching here, and will continue.
Here is a site that tells how to make rubber molds of rocks so you can make more rocks. They are small rocks that fit in your hand. But, the information could prove to be helpful when making large formations.
I've been experimenting with making rocks from my pile of concrete rubble from an old patio we replaced. I'm building a pond and need to have flat rocks to surround the pond and hold the liner in place. I also need to get rid of the concrete rubble. I've used a hypertufa mixture of topping mix (sand and portland cement) and peat moss and mixed in a little black powered colorant for cement. I used a concrete bonder the helps new concrete bond to old, painted it on the cement pieces, then used the hypertufa like clay and pressed it on. I'm liking the results so far, but it's taking a while to cure. I'm going to be experimenting with adding different colorants to the cement during the mixing process, as I am crafty but not artistic and know that if I try to paint the rocks, it's going to look pretty bad. I'm also going to experiment with using the rubble as a base for making rocks that are not flat. Since there will be plantings surrounding the pond, and since I have no problem getting moss to grow on rocks up here, I think these will work great. Keep posting about making rocks, because that's how I found this page in the first place: searching for info on making rocks. The more ideas, the better! I have a photo but can't seem to get it to post, so I'll get my husband to show me how when he gets home (new camera and software - steep learning curve).
Hey, thanks for all the welcoming words! I'm psyched to be able to talk gardening and rocks with others of like minds.
Okay, here is the picture of one of my 'rocks'. You can see that it's not yet cured, but that the peat moss is giving it a nice mottled look. If it's too light when it's cured further I may experiment with darkening it. Any ideas?
The shaping is actually very easy. I just go with the general shape of the concrete piece, keeping the edges nicely rounded. The top, flat part of the concrete (the part that used to be walked on when it was a patio) is actually the bottom of the new 'rock', making the rock easy to place around the pond. This means that the top of the new 'rock' is already irregularly shaped. Some pieces are anywhere from 6-8 inches high. This concrete was really deep. To make more of a boulder shape, I'm going to morter a smaller piece of concrete on top of a larger one and then pack the tufa mix around it. Also, I want to experiment with making the tufa with less peat moss.
I bought some Concretech powdered colorant in a mossy green and in a dusty rose. Very pricey. My next rocks will incorporate a bit of color.
That cement colorant is very pricey isn't it? I have been thinking of having a paint dept. match a sample of local rock and mixup a batch of exterior paint. Has anyone tried that to color concrete? I will probably ask that question in the "Handyman Forum" too.
I've painted concrete before. A birdbath and a few planters. The exterior paint did not last. I primed it and it still didn't last. I've used both latex and oil based paints with quality primers to no avail. It flakes off in not time at all. I have been told that concrete epoxies will work however I have never tried any.
I've read that you can use powdered artists colorants to color cement. Here's a website that sells powdered colorants, as well as mold making materials: http://www.artstuf.com/flexmold2.html. The stuff I got sells in 6 pound bags, which is way more than I need. I'm tempted to order some from this website, but haven't done so yet. I tried my colorants today and I think I will like the green. I mixed in a bit of black with it to tone it down a bit. The red is really RED and so far I'm not liking it. But I may have used too much. I'll look at it in a few days and see what it's like.
Also I've read that you can use powdered tempera paint to color cement
Sorry about that! Don't know what I did wrong, but I'll figure it out later. Two experiments seemed to work well today with the rocks. I used some oil-based wood stain on some of the original rocks that I made. I had an ebony stain and a mahogany stain. I used a rag and just pressed the stain on the rock for a mottled effect, similar to doing a faux finish on a wall. The ebony worked well and darkened the mostly gray rocks. We'll see how it looks when it is fully cured and dry. Also, the mahogany did well, especially when sponged on with the black. I used the mahogany all over one of the red rocks I made yesterday to see how it would work.This rock was still pretty wet so the stain was absorbed well. Don't know how it will affect the curing process. The sponged rock with both ebony and mahogany is seen on the bottom right of the photo.
The other thing I did which I really liked was to pour water mixed with some of the green powdered colorant over one of the gray rocks that has been curing. I really like the result and this rock is seen in the photo below, on the bottom left. I had used a bucket to measure so some colorant was sticking to the side. I just rinsed the bucket out and poured the water over the rock. The water soaked in and also ran off, and bits of the colorant were left behind in a random pattern. It's very subtle. I'm not impressed with how the colors are showing on the photo. It was a very sunny day here. I'll take another one after they've been sitting for awhile.
Thanks! I'm liking the way they look, too. I checked on them today, and I still like the small one with the green speckles the best. The shiny-ness on the woodstained ones has gone away and I can't tell that it's hurt the curing process any. Give them a few more days and I'll post another photo.
John, how's it going using Trois' method of sand casting? Any luck there? I love the look of his rocks and am thinking I could adapt his method a bit so I could use my concrete rubble. Got to get it out of here!
Rootdoctor, any more info about your friend's method?
How hard would it be to make a Grotto out of cement and make it look like really ancient stone? Would be so neat- make it to where you have a small pond inside spilling out- do a blue water treatment- maybe a tiny stream or bubbler. It would look like a small cave and natural spring! Would work nice in near full shade might be able to put some darters in it if it can be made fish safe.
If you could hook the stream up right- you could put some of it in sun ... oh man yeah!
I saw some misters a while back- would make it look all mysterious and misty. OooooooooooooOOoooo!!!!
This thread is giving me too many ideas!!!
Yeah- one of y'all get right on that and post pictures for the rest of us, muhahahha.
Pixeydish, That's amazing what you are doing with the rubble. I live in an area that has NO rocks. My sister has some rocks that I've been telling her that I want to inherit. But she's younger than me so that probably won't work.
A word of caution about using paint. Be sure it is lightfast (sunfast) or it will fade. Some of the craft paints will fade in a matter of days in bright sun. I would use paint intended for exterior applications.
Funny you should post to this thread today. I just placed one of the cement rocks today along a path to the pond. I didn't make a lot of them, they are time consuming. I'll try to post a photo tomorrow. I never did try paint - wasn't sure I'd be able to make it look right. The ones I'll be using have some woodstain on them, but it's very subtle.
Has anyone tried using chunks of styrofoam as a shape for the rock,and covering it with the cement,shaping it to look natural?
and would it hold up to a winter up here without cracking?
Or would I need a mesh or chickenwire...
your rocks all looks so great!
I have not made these rocks, although I would like to try. One thing that I do know about, is Concrete Stain. Specifically, Kemiko concrete stain. Eight years ago, we stained our concrete floors in our new home, and did the work ourselves. This was an inexpensive solution to finishing and moving in, but we now LOVE THEM. Anyway...
The Kemiko is a stain. Mix with water and spray on, it absorbs into the concrete, permanantly coloring it. After 8 yrs, we have had very little fading, and it is extrememly durable! This should be a workable solution to coloring the rocks. The stain comes in numerous natural colors, and is used by spraying it on, and can be done in layers, or steps to make them look natural.
Wow, thanks Mel! If only you knew how easy they were! Time consuming, but easy as heck. I'm familiar with the Kemiko stain but I haven't been brave enough to order any. Sounds like a homeowner can handle it, though so I might do it in the future. I wonder if I could color my patio made of broken concrete chunks with it. Also I have some concrete walls I made for the garden that look like stucco. Right now they are just cement color, but I'd like to stain them. I bought some stain at Lowes for concrete but I'm not impressed. It's basically just a paint, not a stain. It sits on top of the concrete and forms a solid color rather than the more subtle efffect I'm after. What gives me pause is that with many concrete stains, you must etch old concrete with acid before staining and I don't feel confident about doing that.
Here's my biggest wall.
Thanx for the heads up Scoot,I am hoping to add to this thread with a nice Easter Island head this spring,I am planting the Bamboo for it this winter.I have an idea of doing the head the same way the stone is done.
Thanks for the niceys on my wall! It actually looks a lot better now, or at least it did at the end of the summer. I have it all planted with low growing sedums.
That flat seating area is the perfect size for my rear end. In fact, I used my own bottom to measure for that place! I wanted plenty of room to sit, as the wall is exactly the right height for me to sit on. Coincidence? I think not! LOL There's another sitting place on the other side of the wall. But I always have to kick my cat off to get to either one of them.
I simply had to jump in and say "this is the forum that pulled me in pass the knees" sure~ I've been wading around in the plant search for quite some time...dawdling on a membership but when I found 'Hypertufa and Concrete' I found I was no longer content to wallow in the shallows.
The work I've seen here (and I've just started viewing) has the artistic creativity that I've longed for.
I have a simple water feature, waterfall~stream~pond, and I love every little thing about it...however! I want some bigger rocks for naturalizing. I need reinforcement on the waterfall hill, a floating stone step for crossing the stream, (the pond liner needs replacing~oh how I'd love to follow in rootdoctors friend Bo's footsteps)...I need this forum!!
Thank you so much...I look forward to reading more and perhaps some day I will have a project to show also.
Thanks for the warm welcome goldfinch4 and Pixydish.
Just for a quick starter...yesterday I tried the homeformula 1 pt salt, 1 pt water, 2 pt flour~~~ just because they were handy. Two rollouts later I made and baked, my first castor bean leaf, SA~WeeeT... cant wait to get into playing with mock rock mixes (this just might give winter a whole new perspective)
Nice path you've made there Pixy... do you pour right into the ground? So much to learn~~~So happy to be here.
Area that needs mock rock around the sides and back of the waterfall hill.
I've been trying to get back to some concrete work but life - in the form of hurricane watches - has been getting in the way. I've made some real rock paths and they held up well in the tropical storms and my kitchen didn't flood!!!!
Saw a spread in a magazines about like I want to do on a back hill. Then read where they brought in backhoes, etc. and said oh, well. Someone even stole my pick so I'm down to shovels. My cashew nut trees are growing and will soon need to go in the ground. However, we've come this far with shovels and I can always buy another pick (on the first of next month).
MMMM! Cashew nuts! Glad to hear the hurricanes didn't flood you.
Elf, here are a few photos of how to make these stepping stones. A lot of the concrete work I do is by way of recycling broken concrete (known in these part as 'urbanite') from an old patio that was demolished before our remodel. Our concrete pile is getting smaller.
They all start out as pieces of broken concrete and a piece of hardware cloth is placed on top of them. I used bagged mortar mix which I colored with powdered concrete colorant. I used just enough water to make it workable and packable.
I use a bonding agent which can be purchased at the big box stores and looks like elmer's glue. Making sure the concrete is clean of any dirt, etc, you brush this stuff on all the surfaces, especially the vertical surfaces, then start packing the concrete in all the spaces and around the edges.
When you are finished packing, they look like this. Then I use a round edged trowel and smooth the surface until it looks like I want it to. It depends on the look you are going for. I was going for something that looks a little like water-smoothed basalt. We have a lot of that around here.
Here's a finished one. I used a tiny bit of the black powder, sprinkled randomly on the surface and smoothed it in to give it some darker patches. Now all you have to do is keep the animals off of it until it cures.
awesome Pixy...I'm all excited about projects just like yours. I've often thought "there must be ways to use old concrete" Thank you for showing me how its done. And I know where there are several piles of it just laying about too. So many things I've seen on here that I'm already dying to try out. I also like the idea of playing with the styrofoam form, I was wondering if you could piece pieces together and then shape it. I work at a health department and they are always throwing out styro boxes...could always use them for troughs ... but I want so much more.
You can definitely piece styrofoam together and then shape it. Depending on what you want to do, you could either use a wire form over it, or apply the crete directly to the foam to cover it. If you are using it as a mold, you may want to use vaseline as a mold release. There are lots of things you can use for that, other people may use something else for a release. There are many ways to use your old concrete. I built several walls with mine; filling forms with the chunks, packing/pouring fresh concrete around them, then taking the forms off and using stucco to finish the sides. You can use a lot of old concrete that way.
Good news - I found my pick!! So I'm back at work reshaping part of my arroyo, getting it ready for dragonfruit and trees and...
When I was at the dump the other week I spotted a pile of styrofaom with reenforcing wire around it, presumably left over from a construction project. I made two trips to get it all!! I think it will be great as the basis for a couch and some big chairs and the scraps can be used for rocks. The wire that's around it can be hitched together, minimizing the need for glue.
Must do more tire terracing and paths first, then I get to play some.
wow! great find katiebear...and here I am just getting started and telling all my friends "styro~~you find it, I want it"
Can't wait to see all you do with it. A couch?...really? is that for outdoors (don't mean to sound silly but is it?)
Yes, I think this will be great for outdoor furniture. With concrete over it it's too heavy to use inside unless I know that I am never going to want to move it. As it is I have to decide on a permanent location outside, I think. The foam will make it lighter than if it was all concrete and it will cut the amount of concrete needed, but it will still be heavy.
My friend Tony who works for me and I have on ongoing challange to see who can find a use for something the other considers trash. He looked at me quizzically when I happily pulled this out of my van but quickly agreed that it will be great as a base for furniture or whatever else we might want to build. Anticipation about working with this has got me working hard to finish the terraces for my dragonfruit so I can play with foam and concrete.
We made one plant cover thing (hard to describe as i'm just home from a trip to Ca.). We are starting to pour a lot of the molds which I've collected over the years. Still thinking about the foam pieces (one of my mottos is "think a lot, work a little). I'd like to make some chair forms, cover them with concrete and then either stain or mosaic them.
Still doing a lot of basic work on the house. Brought back sandbags to insulate the western walls and lower my summer electric bills. Also materials to finish brown bagging the bedroom area.My mind is active, but my knees are shot.
Will keep you posted.
We did pour a grotto in a mold I got and donated it to a fundraiser for an animal clinic. It sold for $50 so they were pleased.
Check out some of the "garden railroad" hobbyist sites. Many of them have ideas for concrete rocks, as do zoos, which might put you in touch with area artists if you don't want to try making them yourself.
Acid stains are great, as are the powdered pigments that can be found in "big box" home improvement stores with the bagged cement and mortar products. Ask a concrete contractor for ideas on where to buy from concrete accessory stores. They are expensive to buy for small projects such as rocks, as they are scaled for bigger items such as patios, driveways, etc., but maybe you could share with neighbors to keep individual costs down. If you need just a tiny bit for experimenting, a contractor or ready-mix producer might be willing to give you leftovers from their projects.
The warning about concrete poisoning should be heeded. It can be serious and debilitating. I keep diluted white vinegar in a spray bottle to neutralize any alkalis from concrete that gets onto skin or clothing accidentally. It even helps with tool cleanup.
I have had to move and may I tell you~WOW~ the plans have just started jumping! I now have slopes and sm. hills to play with. I will be needing to make some steps so it will be safer to go down, right now you can slide on the pine needles...LOL...not good!
I am wanting a small stream on one side with a creek coming from another direction, to join it before it drops into the last falls before the pond.
So much info here will be used as I need to build the pond up some, rather than digging down. I have about 6-8 inches of sod...then its all wet, natural springs, it is just to bad I cant just dig out a natural pond. But I think these will be easier to keep clean. I just bought a 17' x 12' liner, 6 cans of waterfall form sealant...have moved 2 yards of small rock (from old house w/ 2 yards to go). And have pulled the old pond liner and 5' x 50' stream liner, it's almost all here. Then, its really work time!
I am getting very excited
Now Where did rootdoctor go? I wanted to hear more from him...he and Bo do not live that far from me. I would love to see some works or get some hints.
I actually am going to make a grotto to inside a volcano next year. It will be housing for for my pump and filter system and the start of the waterfall and down a 22' long stream. And I actually have a fog machine already. Reason for the volcano is so the bio filter can get sunlight. Going to incorporate pools and planting niches along the drop for ferns and such. I plan on using the expanded metal & lath method with the 1" concrete on it as described by jwkaren in thread: http://davesgarden.com/community/forums/fp.php?pid=1356564
I'm sure it will take all of next summer to build.
Great job Pixy, rocks came out looking great and a good way to recycle concrete.
Here's picture after thyme took over the concrete pavers around the small pond.
Home Depot has glow in the dark powder in the grout section to add to grout for a really cool effect, would look good sprinkled on uncured faux rocks but really expensive, was around $36 for what I'd guess was about 1/2 oz.,... just sayin.
