Cone 6: Oyster is a variegated cream/brown glaze that exhibits gray/purple undertones and breaks brown.
Cone 10: Color changes to a variegated brown/cream. Increased movement.
TIP: If your kiln fires cool the glaze finish can be brown. If your kiln fires hotter you can get an iridescent finish. Re-fire the piece if you don’t desire the brown finish you get when it is fired cool. This glaze has a gloss finish. If you like Green Tea and Capri Blue combos, then try oyster because these three glazes are in the same glaze family.
