Failures are failures. What to say more… important is it to learn from them.
The most recent ones are as follows.
The below nice agateware shaving bell changed its geometry in firing. My hypothesis is thatthe root causes are:
- Too high temperature for mixed body (simple porcelain would have survived)
- Not symmetric stand which supported them from inside in the kiln shelve
The following one is very similiar. Both pieces do not fit each other anymore. Will have to be used separately.
The box below suffers again from high firing of mixed body with wrong support in the kiln – the lid is badly deformated. After bisque it was a perfect fit.
This nice box cannot be opened. The glaze made both parts sticking each other, hopefully not for ever.
