Is plaster of Paris OK to use for a glass molding material (e.g. slumping
base.) Are there any special temperatures to be aware of etc??
Any hints also please?

I use a 50-50 mix of Hydrocal (plaster) and 200 mesh silica flour (brand
name I use is Silco-sil). Works well for casting, although there are
better (and more expensive) materials.

i can add to your discussion a bit, as i have done PoP molds with glass...
the material is fine, but you need to add silica (i hope i remember that co
rrectly) in order to keep it togehter under higher temps. plaster is great, very flexible...
good luck
