In the threads about fiber paper there's been a lot of discussion about pre-firing. I al so know that folks say it's not needed with thin-fire - but many times I get scuz on the edges of pieces with thin fire underneath. Woukd prefiring prevent this? (Or will thin fire crumble under prefiring?)

If I was going to lay strips of glass at right angles to each other and the particular glass is prone to devitrification, I'd obviously use an overspray. But - must I be super careful to not get any in the "between" places or will it "Mature" there and be OB.

I would like to first fire some single sheets of regular bullseye to just round the edges before slumping them in molds, can you tell me a balol park temperature to be looking to slop the processing?
