studio safety: kiln placement / wiring

updated sat 31 aug 96


MARK JOYCE on tue 6 aug 96

Mentors -- I have recently purchased a used electric kiln which I
plan to put in one of the corners of my in-progress-studio. The
studiospace is the last 16 feet of our 15'x50' "in-line" garage. (No, I didn't
build it, it came with the house.) The kiln came with a venting hood
so for now I'll plan to use that also.

My questions:
1. How far from the walls would you recommend that the kiln be
minimally placed. The walls are currently open wood studs on the
inside with particle cedar siding over particle board sheeting on the
outside. Which brings me to my second question.
2. What kind of interior heat resistant wall covering would you recommend for th
corner in which the kiln is placed?
3. The kiln had been directly wired to a switch box on the wall. What
are the pros and cons of direct wiring vs putting a plug between the
kiln and the switch box. I'm going to need to have an electrician
bring electricity to the garage anyway so the wiring can be planned
from scratch. I'm already considering having a small separate breaker
box installed out there to provide some separate circuits for the
power tools.
4. While we're on the subject of electrical power, most of the
studios I've worked in had their outlets or strips "bench high" on
the wall, as one might expect. I have seen some studios where the
outlets have been placed overhead instead. I'd be interested in
hearing some of the pro/cons experiences you may have had with the
overhead alternative.

I hope the ensuing responses will be useful to many of you!

Good morning Mark

A minimum of a foot (Remember your floor should be heat reisistant
as well). Use "cement board" as heat resistance and have it placed on
spacers so that it does not itself touch any wood. There is special
fire treated white wall but cement board (about 1/4" thick) is not too
expensive, although it is a pain to cut tot he right size (get your
hardware company to cut it for you). It last forever and will not
burn at all.

Direct wire with a breaker for the kiln switch.
