Hi :) I was wondering whether anyone has used their pottery kiln for
various glass procedures. I understand from a kiln manufacturer that this
is possible though results may not be as predictable as with a glass kiln.
Thanks for any answers.
Cheers from Nova Scotia,

Judy..i have used my pottery kiln for glass...for years. They only problem i
had..was dont use the same shelves for glass that you do for pottery.. Clay
seems to leave them a little rough.. And of course... use alumina based shelf
wash.. nothing silica as it will stick.. The cool down has not been a
problem. The kiln cools slowly enough to handle the glass. so when you cut
it off. flash cool it for about 10 seconds.. close the lid and don't open it
again..let it get complete cool before you look inside.

Judy - I've used the electric pottery kiln (it's a Skutt) for both glass
fusing and slumping. It works fine - I like to peek to tell when the glass
is at the stage of fuse that I want, so I'm limited to using the top
(visible) shelf unless I want to risk whatever happens underneath. The kiln
manual has a suggested program for glass firings which, of course, you can
modify to suit your glass and design. I use a kiln wash on the shelves that
is made for glass fusing - it's bluish and turns white when fired so you can
tell if you've got fresh wash on the shelf. Hope this helps. Feel free to
contact me offlist.

Judy,
This is entirely possible. I assume you mean slumped or cold glass. the only
trick is to learn to fire the kiln to the temperatures you need and then
hold it there for annealing. The only other difficulty if using gas or other
fuel is to maintain a neutral to oxidising atmosphere. an electric kiln
should present less problems except for setting it to hold temperature and
then fire down for the annealing process.

I have used a small electric kiln for slumping and fusing glass. What makes
life less complicated is a good controller, lots of ramps are needed for all
that annealing.
