A report on Dorothy Cockrell's experimental workshop on Separation Enamels - Cirencester 1998

Jean Currie

Eight enamellers assembled for a workshop and not one of us knew what separation enamel looked like, let alone had used it previously. In fact, the lead-free separation enamel from Thompsons, which we were to use, was in reddish powder form. It had advantages over the old lead bearing separation enamel in that it contained no lead, was available in a dry powder as well as in an oil base, left no residue after firing and allowed work to be done on flat surfaces.

We were to learn that when painted or sifted onto a fired enamel surface, separation makes the surface it touches runny and pushes the surrounding enamels aside when fired.
