It works on bisque as well as on greenware - use a bit thinner on bisque than on greenware.<br />Can add more Co to get darker - depends on the thickness of application and on your covering glaze.Newfoundout Potterhttps://www.blogger.com/profile/06962914877696149188noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-12473932094484726832011-12-20T12:02:13.276-05:002011-12-20T12:02:13.276-05:00I use gerstly borate and frit with my stain or col...I use gerstly borate and frit with my stain or colorant... (I work in majolica) I add glycerin to get a brushablity that is more like ink on paper. That was tip from Linda Arbuckle that has worked well over the years. What temp do you fire at? Depending on the glaze I find that blues in particular run under clear glazes above low temp. It can be lush if planned on.smartcathttps://www.blogger.com/profile/15430370214403895826noreply@blogger.comtag:blogger.com,1999:blog-6638497050839732163.post-91837089102065688292011-12-20T11:25:40.739-05:002011-12-20T11:25:40.739-05:00Kawai Blue
