I've glaspowder and I would like to try to use it in a glaze and give it =
I would like to get a crackle effect with it like in an high expansion =
What can I use to give it certain colors?
I've tried to mix it with a lime green stain and fired it at cone 9. =
There was not any green result.
In another glaze base I used the same green at cone 9, this gave a nice =
lime green result.
The thing is I want to get a transparent result with colors and cracks.
Anybody has suggestions?

You can purchase many diferent colors and grits of ground glass, from
powder to chunk. One very important consideration ois that all glass have
the same expansion coefficients. They are usually marked on the label.
If you want it in the bottom of a bowl, coat the base with 06 clear to
help with adhesion. Pour in the glass/design, heat to 06 then cool till
approx. 1100 degrees. Slow the cooling and spend about three hours
getting to 750. Then slow cool the rest of the way. Its not a perfect
science, but it works.
