The only tables I have available are wood but I'm wondering if I
use a heat-resistant pad and some tiles if I would have enough
insulation to keep from torching the wood table.
Brian, no kiln on the market today should get hot enough on the
bottom (or elsewhere on the outside) to burn a table. Nonetheless,
people usually put heat-proof material on the surface, since hot
objects may get dropped or set down on the table. Ordinary bricks
are fine, or my personal favorite, cement board (sold for under a
tile floor, at the home center).
