Interesting project. Can you elaborate on the ceramic involved? What kind of cone temps would you need?
With kilns requiring substantial energy for a high temp firing I'd be surprised if there were one on the island. We used to do firings with diesel in college at a friends backyard kiln but we couldnt get much better than about cone 5-6(on a good firing day) and he had to change out to natural gas to do his salt firings at cone 10. Diesel was cheap back then and it isnt now.
Obviously there's no natural gas on the island. Not familiar with butane as a fuel for kilns but its probably costly as well, so that pretty much leaves electricity. Ouch.
There used to be a couple of kilns on the island - a couple of artists had them and then sold them when they moved ..... I cannot recall who bought them - too long ago. Will try to search my memory banks on this and see if after a while I can remember.
I was interested to hear the reply for this one. I had a friend/teacher who built a woodfire kiln in his yard. It got to Cone 10 and we got some really cool stuff out of that. Of course, I am in New England and we burn oak and other hardwoods here.
Way back in the day when the Maya ruled Belize and lived on Ambergris Caye, too, they used lime-plastered pit kilns, fired with charcoal and wood, and did some very cool pots and other pottery. No wheel-thrown pottery, though -- just slab and coil.
