I use a variety of kilns:
My main workhorse is Ray Scott ‘Sayvit’ propane gas kiln, which I fire to cone 10 (about 1300°C) with a ‘reduction’ atmosphere. I also have a smaller gas kiln of a similar design.
I have two Raku kilns, one large (made from a converted oil drum) and a smaller version which was made by Ray Scott (when he ran Fordham Thermal Ceramics).
I have a small electric kiln, which I use occasionally for glaze tests.
A wood kiln will be under construction when I get a chance!.
