Fail Number 2

Fail number 2, time to build different vessel with new clay. My kiln at cone 5 fires to cone 4 temp so logic says cone 6 should fire to cone 5 temp eh? Nope six on the dot. No worries though. I’ll make something even better 🙂

This clay, which I believe contains manganese, needs to not be over fired and needs a loooong bisque to burn off any gasses and other things that can cause bloating. Which I did. A 13 hour slow bisque to cone 05. But in the end it blistered anyways because of over firing.
