I just bought a kiln on craigs list. It has something melted on the bottom, it looks like a seriously over fired piece. Porcelain maybe?? It is covering half the bottom. What to do? Any suggestions? I got it for 75 bucks so if I need to buy a new bottom that would work money wise.
Thanks,
Andrea

Clean the crude off by chipping or grinding then Flip your floor over and put the bad side down rebuild kiln on to new bottom side. This will give you a new life on the floor-when you melt the next stuff then get a new floor-until then happy firing.

Flip the floor over so the good side is up. If there are any chunks of the melted gunk keeping the floor from sitting level on the stand, then try to chisel them off. Or you can lay a coil of clay all the way around the stand as a leveling ring.

I will give it a shot.
Thanks so much,

I always put some 1" posts on the floor, and a shelf on top of that. It stays in place, until I need to vacuum the kiln. I find the bottom heats more evenly with that air space under the first shelf.
