Slumping temps are lower

Home Forums Glass Fusing General Fusing Discussion fire polishing Slumping temps are lower


Slumping temps are lower than traditional fire polishing temps. However, depending upon to what degree (as in how smooth, not how hot ;)) you coldworked, the edges may look fine with just a slump.

I have found that starting with a 120 grit diamond pad (on a lap), moving to 400, and then slumping, provides a nice edge. I slump at fairly low temps — no higher than 1220 in my particular kilns (and quite often I skip to anneal before that). Obviously, that depends upon the size/shape you are slumping.
