Product Description

Makes a superb casting slip or the base for decorating slips. It has good translucency even at lower temperatures and fires very white. Can be combined with compatible stains and colourants.

  • Recommended firing range 1220C-1290C

GUIDELINE RECIPE FOR CASTING SLIP USING POWDERED CLAY

  • 25kg powdered clay
  • 35-87.5g* sodium silicate 120tw
  • 30g soda ash
  • 10lt water

*sodium silicate (deflocculant) addition will need to be adjusted accordingly to achieve correct fluidity. Too much deflocculant can have the reverse effect on a casting slip, causing it to thicken, so it is best to add it gradually, mixing all the while. Fine-tuning the fluidity is best achieved with sodium dispex.
