You won't be using the cones any more.

While that's good advice, it's not as though it's not possible to use cones, especially for something (relatively) simple like slumping a single layer of glass. I've successfully slumped by putting an 018 cone in the kilnsitter, turning the power on high, and walking away. There's enough thermal mass in the kiln, and the glass is thin enough, that it seems to cool down slowly enough to anneal reasonably well.

On the other hand, I only did the one project before I built a digital controller for the beast (setpoint only, for the moment, but for now that's enough.)

I second what these guys said; you *can* use cones but you probably won't want to. An analog pyrometer and infinite control switch are inexpensive and can be effectively used to manually control your temperatures, but you'll be much happier with a digital controller, which you can build yourself as Ron did or purchase from a supplier such as

A basic fusing book like "Contemporary Warm Glass" by Brad Walker is another great place to start.

Good luck!

It is nice to have plenty of cheap (?) and beautifull glass. I feel pity if that machine rolled glass is not used for restauration of old windows.
