Oh well to be expected really, the pots were mostly overfired, well all mine were, Tina used beefier stronger clay. Some had melted completely some just gave way.
The trouble we had with gauging the temperature certainly was the reason for the over fire. I am going back to firing at earthenware now, but have not ruled out another stoneware firing at some time in the future.
On reflection, there were a few that were worth keeping and I have gained a lot of knowledge. whether I will be able to use that knowledge to avoid the problems in the future, is another matter. Keep smiling through, like you know you ought to do.
