Notes
- Fine Detail
- Strikingly precise
- wears away quickly - like in fewer than a dozen castings. (GPT says 30 - 50 castings)
- This supports the 3 step mold:
- 3D Print (costly, time consuming, high precision, master)
- Silicone or Urethane mold (cheaper, rubbery / durable)
- Plaster mold (good for 20 shots, cheap)
- You could hit a rhythm of creating a new plaster mold every day, with 20 active molds at a time and a 24 hour pull cycle.
- Porosity of the bisque is critical for underglaze adhesion.
- Fire on the low end of cone 06 - 04?
- Don't get the surface dirty.

Recipes
Plaster
- 1 Liter of Mold
- 1 Kilo of Dry #1 Pottery Plaster
- 0.7 Liters (kilos) of Water
- slake 3 minutes
- stir
- For 5 minutes?
- until uniform, as little as possible?
Slip
- 1.75 specific gravity
- Have tried as low as 1.7, which I like. Update: maybe a bit too thin, though I do like the slight castings it produces.
- 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 a tablespoon of water)
- barium carbonate to capture salts
- sodium ash to dissolve lignite (small)
- filter to remove large lignite
