Recommended Posts

hi everybody, 

i'm a ceramic designer from michigan currently living in the netherlands.

I would like to adapt one of Val Cushing's earthenware recipes to materials I can access in Europe.

I think I have access to most of the chemicals expect for the Frit. Also I was wondering if there was an equivalent to EPK in Europe.

E.P.K. (Plastic Kaolin) --- 10

Grolleg China Clay --- 20

Ball Clay --- 10

(Ferro) Frit # 3124 - 10

Talc - 10

Wollastonite - 10 

Molochite - 30 

+ 2% Bentonite

 

From what I gather so far the Molochite is pretty expensive from where I'm ordering it (Keramikos.nl)

I am struggling trying to understand why molochite is even in this low fire recipe. Molochite is a calcined, high temp grolleg. (Cone10-12)

It's a sculpture body, so they want it toothy. Val Cushing knew his stuff. I would trust his recipes to work.

Maybe there are other reasons as well, but I know one reason is to maintain the whiteness of the body

Neil: the body is rather obvious in application. 10% would be tooth, 30% would be dentures. 

Clore: you are approaching it in the right way: comparing chemistry to the closest chemistry. Perhaps ask your local supplier if they have a product anywhere related to a finer mesh grog. Molochite is sold 120-200-325 mesh. The recipe does not state which mesh, although in the States 200 is the most widely available.
