CeraCast, QuickCast & Jesmonite are eco-friendly safe alternatives to resin, plaster and concrete.
CeraCast is a high-end moulding solution which yields final products with ceramic qualities, uses and strength. It does not require oven baking in its setting process, unlike ceramics. The product is safe and non-toxic. CeraCast is a combination of the purest and highest quality aggregates combined with a natural binder system used since the late 1800s by dentists for tooth fillings. It is also used for manufacturing of billiard balls, surrogate material for ivory, concrete in construction where higher strength and more resilience is required.
