Michelle -
I ran my kiln from the dryer outlet for several years, while we were living
in a townhouse and didn't have any other alternative. We had wires run from
the dryer outlet to another outlet in the bedroom I was using as a studio,
with the connection at the dryer outlet, but another outlet in the bedroom
in case I needed to disconnect the kiln quickly. I had a cone 10 Estrin,
which Larry Estrin rewired down to cone 6, so that the amperage would be
within the right range for the existing wiring. And the kiln had an
envirovent, with the outlet end of the vent duct in a frame which let me
wedge it between the window frame and the open window, but take it down when
not in use. (Townhouse rules did not allow altering the exterior of the
house, even for things like extra vents, and anyway we knew we weren't going
to be there for long.) I had an electronic controller which let me fire
overnight, so I didn't have to swelter and choke while working. The only
major differences to normal kiln operation were that it fired more slowly -
typically about 12 hours for a bisque, 14 to 16 for a glaze firing - took
ages to get up over the last few hundred degrees. And of course the limit
to cone 6. Although I could soak at 6 to get an effective cone 8. Didn't
try pushing it any higher.
