I have been presented with a job to fire decals on commercial tiles in
quantity using standard electric studio kilns. I believe I am going to
run into a problem of even heating in a decal fireing. Do you have any
suggestions as to the best way to achieve maximum quantity with
efficiency? Any help you can send my way will be appreciated.

I have fired both home made decals and commercial made decals on commercial
tiles for many years. I have not had any problems to date. By even heating,
what do you mean? Too much refractory mass vs. ceramic pieces? Hence,
uneven kiln temps? I might suggest that you use commercial tile setters to
reduce the refractory mass of shelves and posts, or use a kiln with a
controller so that ytou can build a soak time into your firing profile to
maintain an even chamber temperature, which is difficult to achieve at
lower cones, especiall cone 017, the recommended cone for most decals. BTW,
most China paints do have a fairly brad firing range. You might wish to
test your decals before firing larger quantities.
Good Luck.

I've been firing decals on tile for a short while, but I have discovered
that a 500 degree an hour rise in temp. programmed into the kiln's computer
makes for a smoother, glossier surface than a slower rise in temp. I use
tile setters and stack 'em double in the kiln right up to the top. Works
fine.
