I finally bought a proper annealing kiln and it saved my last batch

Spent about $1200 on a Paragon SC2 last month after cracking too many pieces from cooling them too fast. Ran a set of six drinking glasses through it last night at 960 degrees, held for an hour, and they all came out perfect this morning. Anyone have tips on programming a slower cool down for thicker marbles?

Honestly, "cracking too many pieces" is my default setting before I got my kiln. Tbh I once tried to anneal a paperweight in my kitchen oven and it sounded like a gunshot when it went. For thicker marbles, I just add a few extra slow cool steps on the controller, like dropping 50 degrees every 30 minutes until I'm under 800.

Nah, that gunshot sound is totally real, I've heard it happen before lol.

Remember that oven gunshot sound? I still flinch thinking about it. Your slow cool method sounds way smarter than my old kitchen experiments. Glad you found a system that works.

Seriously, a gunshot sound from an oven? Sounds like you're either exaggerating or you were making a bomb, not glass. I get that stuff cracks, but that's a bit dramatic. Maybe your oven just has bad vibes.
