Sludge

Glass workers always keep a cup of water on their work stations. You never know when you may have to douse a fire! Seriously...not too often...but, it is a handy place to dispose of unwanted bits of hot glass and many a wonky bead dies a fast death there.

Since it had been a few weeks since I torched, my water cup had dried up! When I picked it up to refill it, I was kinda shocked at how heavy it was. My 8" tall cup was over half full of glass and graphite sludge! So I poured it out on a metal pan and took a pic:

I can see the remnants of a couple of vessels, lots of cane pulls, half beads and bunches of glass!
