I've also experimented with fusing glass bits and scraps into clay with
maskmaking and pottery with good results. Just remember that the glass
will melt at a lowere temperature than the clay will mature. You might
want to do several test firings before firing student works. Keep a
firing log for yourself, so you know what to expect.
With glass fusing I generally bring the kiln temperature up gradually
and back down slowly as well. Most glass will begin to slump at about
1300 F. The higher your temperature, the more the glass will melt or
fuse together. In a workshop years ago with Henry Halem, of Kent State
University/ glass professor, I was told that you can determine the
annealing point of the glass as 50 degrees below its slumping point.
You need to hold the temperature of the kiln at the annealing point of
your glass when bring it back down. I usually anneal the glass for at
least an hour...more if the glass is thicker, larger or more dense
proportionately. Hope this helps.
