How long would it take to bisque fire three mugs?Does it fire to stoneware?How long would a glaze firing take?Many thanks

Hi,

There are so many factors that affect the length of a firing that it is hard to say. Below is an example but it is very much a guide.

If you were to do a bisque firing with a 4 hour preheat, Cone 04, Slow speed, no hold at top temp and an average size load, it would take approximately 15 hours and 20 minutes. The kiln would then take several more hours to cool down, but 3 mugs is the most you can fit into this kiln so it may take a bit longer.

In terms of a glaze firing, this has even more factors that affect the firing speed, but below is another example.

If you were to do an Earthenware glaze firing without a preheat to Cone 06, Medium speed, 0.00 Hold at top temp, and an average size load, it would take approximately 7 hours and 10 minutes. The kiln would then take several more hours to cool down.

We have this kiln in our studio and use it for test firings, and have taken it to stoneware temperatures multiple times. However, this will affect the element life and will probably void your warranty so it is down to you whether you decide to fire the kiln this high.
