I was asked a couple times recently for a guide on my clay substrate. I have copied the emails I sent on those, along with a few pics. Want to thank Matt, Brent, Jason, Ed, and others, for all the info they were so willing to share on clay substrates. Here is what I came up with.
My clay supplier is Mile Hi Ceramics, INC. 77 Lipan 303-825-4570
You are looking for RedArt and Bentonite.
Clay Recipe
3 Quarts RedArt powdered clay
1/2 Quart Sodium Bentonite powdered clay
1/2 Quart Calcium Bentonite powdered clay
1 Quart Brown Peat OR Coco Fiber (ground up like dirt)
1/2 Quart Fine Aragonite Sand
1/4 to 1/2 cup Calcium Carbonate
2 TBSP Sugar
2 TBSP Corn Starch
Mix all ingredients except sugar and corn starch in a 5 gallon bucket. Dry mix it. Boil Sugar and Corn Starch into water. Use water to hydrate mix. I use about 3/4 of a 2 quart container. Mix like crazy. I use a drill and a paint stirrer from WalMart. The better ones don't work as they get bogged down in the thick mix, get the cheapy with the red plastic stirrer on the end from WalMart.
Grab a handful of clay maybe about the size of a couple of golf balls. Squish clay into about 1/4 inch thick patties. Place patties onto 1/4 inch screen. I made a screen box out of four, 20" 2x4's with the screen nailed to the top.
