Some of my students are working on a white earthenware tile project, and =
have
been trying to come up with a formula for a alkaline copper blue glaze that
matures at cone 06. It needs to not shift or run, as they wish to decorating=
on
top of it. We have several alkaline frits in our store room all ferro. =

31953270. We also have Lithium. (I use to have a formula for a nice =
copper
blue using lithium, but can not find it.)
Also, does anyone have a formula for tube lining. Can casting slip be used =
for
this? Thanks in advance Ron
