I'm wanting to start experimenting with casting glass in my ceramic
kilns. I'm also considering upgrading to a larger kiln for going "into"
an art making business. I have a small, wide Skutt I think would be
suitable for glass firing, though it is a ceramic kiln. Apparently,
glass controllers are much cheaper than ceramic controllers and I don't
really know the difference other than that. I imagine you can use a
ceramic controller for glass but can you use it the other way around?
I'm considering buying a large Skutt, (27" wide, 27" deep approx.), with
ceramic controller, but I doubt that I'll be doing so much glass as to
warrent the use of the full kiln. If I put a glass controller on the
smaller kiln will I be able to use that controller for ceramics as well?
Thanks,

The difference between controllers designed for ceramics and those
designed for glass is that the ceramic version includes Cone-Fire mode.
The glass version does not. The other mode, Ramp-Hold, is used on both
types of controllers.
Also, more and more glass controllers are 3-key instead of 12-key. The
3-key controller is less expensive than the 12-key and contains fewer
features. But they both use the same Ramp-Hold mode.
Some glass controllers also contain programs specifically designed for
fusing and slumping glass. These are simply Ramp-Hold profiles that you
could also enter yourself into the controller. I prefer to enter my own
glass firing profiles, because glass fusing and slumping temperatures
vary from brand, color, and batch of glass.
So essentially, glass and ceramic controllers are the same thing. One
simply has Cone-Fire, and the other does not. The hardware is the same.
In fact, the Cone-Fire mode is usually loaded inside the memory chip on
the glass kiln. It has been programmed not to appear, since Cone-Fire
would add confusion to the glass fusing process.
