Clayarters,

Ok, the next question...is there any hope of using glass (besides glaze)
on the outside of ceramics without too much breaking, cracking and
general disorder? What I'm trying to do is 2 things:

--using broken bottle glass on the outside flat rim of some plates, where
the glass, if it melted in place without thinning and spreading.

--using this same glass on the outside of pots to be pitfired and
wrapping them to the pots using aluminum foil. I figure the glass will
melt and run to some extent, but I'm wondering if it will even STAY on
the pot. Is there a point in glass melting where it kind of gets gooey
but not watery?

I've heard a little about how the expansion of glass and ceramics as they
dry is very different and that's why they cannot stay together all the
way to room temperatures. Can someone clarify this for me and give any
advise on these projects? Thanks...
