I must say I have fired hundreds of loads in my 6 different kilns. All electric various sizes but my favorite way to fire is pressing the numbers on the electronic controller and pushing the start button. Then I go home and go to bed.
I'm just being a smarty pants. The stuff with the horse hair is very nice and I don't know of any other way to create that effect. I have only one question. How does the horse feel about it?
When firing Mother of Pearl overglaze on a piece that will also get a gold overlay, you can fire them at the same time as long as they don't touch eachother.
The MFR states that they need to be fired separately but it's not the case.
Also, on the overlays... Less is more.
To keep from powdering the Mother of Pearl, use a very thin coat. It fires between 020 and 018, as does a gold overlay.
