Using horticultural glass for tests

I'm cutting up horticultural glass, to try and mimic a bigger piece ... so I can see if there's a lot of bubbles, and also how long the kiln schedule takes.

I've been warned that this cheaper glass won't behave exactly like my art glass, but it should show I'm going in the right direction!

Results when it's ready ... this nee Pro-Fuser kiln is really efficient, so it takes a while to cool down!
