An older electric kiln, about 26 inches across and 24 inches deep inside, that has seen relatively little use. I built its ramp/soak controller, and a welded steel base on casters that lets me move it around the shop. It fired the clay bowl my daughter and I made in the Home Eng series.

The kiln on its welded base, with its controller beside it.
