Dear Friends,
Here are our best glazes from the past 20 years and since being forced
to
drop chrome and Barium from our chemicals. We did substitute a chrome
Mason stain in a teal glaze.There are 14 with some bases listing
suggested colorants for variation. They look like stoneware to me. We
reduced at ^09-04 (about an hour) and again at ^6 tile the kilns even
out or for another hour. If trying for good coppers reds, keep the
atmosphere just slightly in reduction all the way. Lately I was throwing
wood sticks in as the kiln cooled for several hours after reaching
twmperature. My imagination or not, the reds looked great. -a clayart suggestion

I second that. Thanks for taking the time to post these glazes. We will
have a great time trying some of them out in our little gas kiln.
