Recipes
Plaster
- 1 Liter of Mold
- 1 Kilo of Dry #1 Pottery Plaster
- 0.7 Liters (kilos) of Water
- slake 3 minutes
- stir 5 minutes
Slip
- 1.75 specific gravity
- too much deflocculant = gels quickly
- Just right = gels eventually, like hours
- OK - never gels but very liquidy
- recipe 1
- 40 fl oz thick oatmeal clay
- 12 ml sodium silicate solution
- 1/4 tsp soda ash (dissolved in water)
- barium carbonate to capture salts
- sodium ash to dissolve lignite (small)
- filter to remove large lignite
