Hi Mark – Sorry to hear

[Anonymous]

Hi Mark –

Sorry to hear about the frustration.  Have you tried the schedules here:

They are very conservative — but a good place to start.

It is normal for different kilns to require different schedules — they all read temperature a little differently (even across the same models from the same manufacturers sometimes).

The “peanut brittle” sounds like you are saying it broke up.  If it broke on the way down (you’ll know because broken edges will be sharp) here are the possible causes:

– incompatible glass (sounds like that isn’t likely)

– it stuck to the shelf

– improper annealing (doesn’t sound like that kind of break)

– thermal shock

Any chance you can post a photo?
