Hi Audrey (and other Satin Matt glaze admirers),
Below are some recipes that I have for Cone 6 Oxidation Satin Matt glazes.
A caveat: I have yet to test them, so be sure and mix small test batches
first.
If you intend to use the glazes strictly for nonfunctional/sculptural ware,
then skip the following sentence: If you intend to use any of these glazes
on functional ware that will be coming into contact with food or drink then
you need to find out if the glaze formulation itself falls within safe limits
for cone 6 satin matt glazes and then have the glazed ware tested by a lab
(Alfred University) for oxide leaching to be sure that it is safe for use
with food or drink.
So, without further ado, I bring you the Satin Matt Glaze Parade:
Clear Satin Matt/^6 OX
James Chappell, The Potter's Complete Book of Clay and Glazes

Before adding water, add 2% bentonite and 1% V-Gum Cer
to the glaze batch and dry-mix the ingredients thoroughly.
This will help keep the glaze in suspension as it likes to
sink down to a dry hard mass.

That's all she wrote for now.
If you test any of these glazes please share your results with us (good or
bad) and, if good, then post the recipes and results on the ClayArt Glaze
Database to complete the circle of sharing.
I hope you find at least one, if not more, glazes that perform well on your
clay body and in your kiln.
Happy Testing!

Hi, I have been searching for cone 6 satin glazes and have even checked the
clayart archives and have not been able to find recipes. If anyone has
reliable satin glazes, I would appreciate posting them on clayart. Thanks ASC
