My kids did relief tiles last year. They built them on the drywall
squares. They finished them in one double period. I had extra drywall
to lay ontop of each tile. I put them to dry in the kiln room on
shelves that were covered with a piece of plastic the first day. I
don't mean that the pieces were tightly wrapped with plastic, just that
the fronts of the shelves were covered with plastic to prevent drafts
from drying out the front faster than the sides on the exposed edges.
After a day and a half, so much moisture was sucked into the drywall
that I was able to take off the top layer and just finish air drying
them. The only ones that had any trouble drying flat or without cracks
were the ones that were TOO WET!!! due to a few kids not following
instructions during the making of the tiles. S cracks showed up on two
like that and that is totally a water issue. I saved the drywall and
dried it out so it wouldn't mildew. I can recycle this time, but not
sure how many times I could reuse it. Space is an issue with drying
flat tiles. If you don't have some sort of rack, do one class at a
time, which is what I did.
