Thanks to efforts of various members, we have a kiln!
It is apparently a Gallenkamp Muffle Furnace exact type: unknown.
Please be careful hacking this as there may be asbestos inside of it. The asbestos should be internal (i.e. only a risk if you open up the back etc) but please be careful and wear a mask (asbestos safe) until confirmed one way or another.
The kiln has been used several times now. The door is a bit broken, it will still insulate enough to get hot, but it is hard to open and close. I attempted to cement it back together with fire cement, but the bricks really need to be taken off and replaced with new ones. Getting them off seems difficult! - Luke
Plug it in, jam a stick in the back to hold the valve open, put stuff inside.
The kiln is working, though the thermostat is not functional, so when you're using it, you have to switch it on and off, as you are the thermostat. Abby has had a new thermostat delivered, but he hasn't had time to fit it yet. If you'd like to help when he does, then we'll give a shout on the mailing list when it's happeneing.
