Red flame clay – Gemica Impasti
20-339 from lathe.
20-340 half plaster press press.
20-341 iron mold press.
APPLICATION
Suitable for lathe processing, plaster or iron moulds. The very low thermal expansion makes this clay resistant to direct exposure to the kitchen flame, and is also suitable for making objects for the kitchen oven, or in any case subject to thermal shock. Due to its physical characteristics, the surface of the enamel will always be subject to craquelè.
