Am now in posession of the final glaze ingredient, Dolomite……and a boot full of various other bags, sacks and jars from Desmond….and still another trip is required. Swapped it for a couple of flapjacks….seemed a fair deal!
All this glaze mixing makes me wish I had paid more interest in Chemistry…..I didn’t know at the time that I would actually have a use for it!
Dolomite, which seems to crop up a lot in glaze recipes is a sedimentary carbonate rock and a mineral, both composed of calcium magnesium carbonate and found in crystals.
Dolomite is used in glazes as a flux, which means it lowers the melting point of the glass formers in the glaze.
