broken glass

Just a note on my last project. Even though I let the mold dry for a long, long time it still exploded in the kiln. I learned that I should allow the kiln to heat slowly, I had the setting on fast, my bad. Oh well, I'll try again later. Right now I'm doing my broken glass experiments.
I'm breaking glass into small bits, not too small because it doesn't melt right. So I got my glass and I broke it into smallish pieces. I put the pieces into a terracotta tray I had coated with kiln wash. (another thing I wasn't sure I did right... we'll see.) But I set up the kiln with a schedule I got from Glass With a Past I know she has a better kiln than I have, but I'm trying her schedule as a way to start. I will make adjustments if it doesn't work. But here is the schedule. "300/hr to 1100 hold 10 (this stop makes sure your mold and glass are all the same temperature) 300/hr to 1650 hold 20 9999 to 1020 hold 10 (annealing stop) 200/hr to 750 then off" 
I'll try to remember to post pics when I'm done. Lets hope what I did isn't rubbish.
