There has been a few questions asked about what temperature I fire my pots at. Very importantly to me is the fact that where I live it gets quite cold in the winter and as such I need my pots to be resistant to frost. It is not unusual for temperatures to get down to minus nine degrees Celsius and at those temperatures pots that have not been fired to a sufficient temperature crack, in fact they may only last one season outside.
Now I have set the background, the pots are fired to 1220 degrees give or take a couple of degrees and although it has only been a short period of time there have been no issues so far. A couple more of the more traditional pots that I have made.
