I think you would be happier if you got a heavier cord. There are
extension cords made for airconditioners that have #12 AWG wire in them and
this will handle the load without getting warm. If you use too small a wire
it will heat up under load and reduce the voltage at the kiln by a small
These extension cords are sort of flat with 3 wires in them and the one I
have on my small test kiln is gray plastic. It works fine and my kiln is
rated 20 amps.

There's no problem with using the end of a "contractor type" extension cord.
What you do want is the male end though...not a female. ( just refer back to
basic birds and bees technology for a visual aid, if in doubt just pull
someone's pants down )
However, you should look for a minimum of 14 ga. wire, preferably 12 ga.
12 and 14 ga extensions are pricey if you only need a few feet. One of two
options are available.
#1 Buy the extension and an additional male end. After you cut off what
you need, attach the male to the remainder. Voila, a kiln cord, and a
slightly shorter extension.
or #2. Just buy 4 or 5 feet of 12 ga. cord, a male plug and make your own.
I just do option 2 all the time...lots cheaper.
As far as today's wire being better ....well, as far as I understand it,
physics hasn't changed and pure copper still conducts like it used to. I
think he was trying to sell what he had on hand......as you mentioned.
Overly cautious 20 years ago.??!!!! Well, take it with a grain of salt,
not everyone working in a hardware store is a rocket scientist.
