Firing Temperature: Δ6

Source/Alternate names: Donna Kat

Source/Alternate names: similar oxides to Yellow Brown Opal and Brown Opal

Notes: Donna Kat: This glaze can run - test to see what works for you. Over Toby/Randy Red it gives a caramel gold colour. It does really
lovely things over Floating blue and Raspberry as well as with other glazes. It fits Standard Ceramic clay 112 (same as 225) and
everything else that has come from there as far as I know (the studio has gone through quite a number of different clays and has not
had a problem with it).
