Attached is a glaze I sent out recently to Clayart. Now that people are
talking about melting points of materials, here is a glaze that you
alter dramatically by leaving out the flint. The glaze with flint is a
wonderful smooth cone 10 glaze that I use on the inside and outside of
pots. If you leave out the flint you will get a beautiful orange
white stoney mat glaze. The dolomite in the glaze helps develop the
orange. This version was used a lot by Ken Ferguson in the 50's and
'60's. It is more orange when used medium thin and becomes to flat if
used overly heavy. It is best on a stoneware body with a little iron in
the clay. No, it doesn't require tin to make the color an burnt orange.

Even when leaving out nearly 19% flint the glaze still melts at cone
10. =3D20

23.6 Epk I usually replace 5% of the Epk with calcined Epk because of
the wet dry shrinkage.
