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
  • Have tried as low as 1.7, which I like.
  • Have tried as high as 1.85, which is too thick for me.
  • Seems to effect the thickness of the casting - more so than does the dwell time before pouring off.
• 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
