I collected this chart of glazes for my glaze workshop. All these =
glazes contain zinc, which may affect chrome greens. Those which =
include a color in the name were "finalized" by the originator around a =
colorant. Where that colorant is a flux in itself--as copper is--the =
untinted glaze may prove too fluid on some clays.

These glazes may not work on all bodies. Test on at least three c.6 =
bodies and over white and dark slip.

I have given attribution where I could. No idea where some of these =
originated.

The Jann glazes were given me by Jann Welch, now of Bakersville, NC.



And thank you, Mel, for posting the whole Megillah
