Thanks to all the posters in this forum, I have a "crop" of 'tufa pots. Most of my molds came from the dollar store and Goodwill. But I wanted to make a modern-style planter and tried to make my own mold. As you can see in the pic, I used foam house insulation and a lot of duct tape. I had to destroy the inner mold to remove the planter. I used vegetable spray as a release agent. My question is; does anyone have a better idea?

I agree with Plantsforpeg - you did an amazing job and the fact you repurposed items to do it worked for me! May I ask your recipe - I am trying to come up with the best mix - I have only done this once, and even though I liked what I did, I know I didn't do it right! I only used cement and shredded paper - I would like a lighter mix.

My mixture is

1 part Portland
1 part Pearlite
1 part Peat

I think the curing is a key to getting the finished product right. I cured mine in black garbage bags for one month. Weekly, I would turn the pots. It has been very hot, humid and rainy in Florida this summer. When I would open the bags, the heat inside was approx. 110F. The first time I tried 'tufa, I couldn't help myself and added sand. I got lovely cement planters that weighed a ton! lol

I'd price them at at least $20 each. Pots like this sell for that much. Do not underprice them. they are beutiful. kb

Very imaginative and appealing liatris. Did you use the same formula for the large container? (1:1:1)

My latest go at hypertufa - for the lizard - I made a sand mould and filled the impression with mixture of shredded/chopped paper and cement - same for the mushroom.
I built up the underside of lizard with netting and glue/render to give it support. Then mosaiced the lizard with found objects: screws, chain, beer glass, studs for eyes and eyeballs of glass beading, porcelain etc. Present for my son-in-law - he wanted a lizard on a rock - seeing as we had to fly to catch up for Xmas, I had to make it light! Mushroom for my daughter! Right hand photo are the collection of mushrooms at home! Happy New Year to all!

I've made cement molds out of wood and also used styrofoam for making "inserts". I used packing tape to wrap pieces. It works good, helps keep the styrofoam from breaking and is non-stick. It also holds up pretty good so you don't have to re-wrap every time you use the mold.
You've done some nice things here.

Thank you Domehomedee! That has given me a great idea - as down the road someone has dumped a huge bag of styrofoam pieces!

You could also build something out of the foam and then cover it with concrete or tufa. I was thinking on something like an easy chair or sofa/bench. Or a block table which you could then mosaic. I found some foam pieces wrapped in a wire cage and have been thinking of things I could shape and then cover. katie

This is a lousy picture but you can still see the insets made from the styrofoam inserts.
This was my first tufa project, LOL, they've gotten smaller from here.

I had great fun - starting with chunks of styrofoam, enclosing it in a huge trash bag, putting chicken wire all around - and then starting the application of hypertufa on the outer surface. I assembled this using a wheelbarrow as the creation platform, and turned it when the uppermost surface had cured. What was the end product??? A huge boulder which now sits on the ground at the entrance to my driveway. The wheelbarrow allowed for a much easier movement. That was nearly 10 years ago. The boulder is doing just fine, and has started to attain a gentle moss covering!!!

Would love to see a photo of that? How clever of you. I have been shown by a Mosaic Artist how to prepare styrofoam with layers of mesh, wire and then it could be mosaiced - but hadn't thought of doing the hypertufa on that!

These photos are of the hypertufa big rock that I created. I will need to take a current photo sometime, so that you can see how it has "aged".

The armature began with large styrofoam pieces inserted into black plastic bag.
That was then wrapped with chicken wire, and was set in a wheel barrow.
Hypertufa was applied, allowing some curing before adding more.
The wheelbarrow then made the moving of the "rock" to the final location so much easier.
