I have a nice cream/white glaze that is glossy but I am trying for a tan
creamy glossy cone 6 glaze/ I thought about testing the variety of oatmeal
glazes out there and found Pike's Oatmeal recipe. Has anyone used it on
brown stonewware clay? Is it more tan than grey tan? and glossy? The SiO=
is 2.850 and the Ratio is 11.15 between Silicia and Aulimina so should be
I thought about Annie's Tan as well but the ratio there is 16.80 (Si:Al)
With the Al being .189 which looks to be too low so I rules it out for
Any thoughts would be appreciated to give me a direction to test.

Eric -- Sorry, I don't know.=3DA0 Michael
Bailey also wrote "Oriental Glazes"
(worth the time and cost, even if you
don't do flame firing, I believe), is=3DA0=3D20
one of the contributors to Murfitt's=3D20
compilation "The Glaze Book" (ditto)
and sometimes writes for Ceramics Review.
We have very vague naming conventions
for glazes, as you know, and it's sometimes
hard to keep track of sourcing.=3DA0 I try to
be accurate, but I end up with glaze
buckets marked things like "Lili Krakowski's --
Tony Yeh's Iron Red/Adapted."=3DA0 I'm not
sure that helps ....
