Slowly things are coming together - still looking for user friendly forum.
I've narrowed the glaze search down to this one (I think, um, er, maybe)

Frit vs Ghastley Borate, don't frits cost more? Frogpond has my head
spinning now with talk of leaching - I'm now soaking some of my plates in a vat of
vinegar - so let's see how the store bought glazes perform.

frit, oxides, borate (can you really use 20 Mule Team borax?) sounds
complicated but the pieces are falling into some sort of shape - flux, silica, Kona,
so many names and yet so many mean the same thing - confused! Jonathan
