Lori, The only problem with using a ceramic kiln is you can
not set it to reach a certain temp and hold it there as is
necessary for the PMC. The ceramic kiln cuts off when it reaches
the temp set, a PMC kiln holds it for a specificed time and then
cools down. Hope this helps....... Nancy Johnson Nancy's Fancies
Howdy Nancy and others, If someone wants an 'intermediate' approach
to this issue, a Robertshaw (or other?) 'infinite switch' can be
assembeld into a few other parts one may have laying around for
about $40. Or hire an electrician to make one one for maybe twice
that (?). Or, I think a nice unit can be purchased from Paragon.
They will only work with smaller kilns, though a 220 versiaon may be
available. With some experimentation, this device will cycle on and
off and a duty cycle can be found which will maintain fairly good
stability. It works quite well on my wife's lampwork bead annealer.
