Hi Leslie,

I regularly use a glaze at cone 8 over coloured slips which is matt but
lets the coloured slips show through. This is in oxidation over a buff
stoneware glaze. In case this sounds what you are after and interesting
to you, I give the recipe below, which I have translated from the UK
sourced materials that I use, into North American materials. Actually
the difference is very small.

David Hewitt-
Thank-you, thank-you, thank-you! I just opened the kiln and I am
thrilled, first try, with your matt clear. Not only that, it single fired
beautifully over both porcelain and stoneware (miller #55)
I also recieved two other recipes which I will try. I noted your e-mail
that yours was similar to tony's.
