Leave the sitter. Digital controllers can fail, but gravity does not. Put a cone higher than you will reach in the sitter. It's there already, so why not have one more layer of fail safe.

The cone of clay to use will have to be an experiment.


You need to fire it at cone 5 or above. This is the mid fire lower range. The type of clay is up to you. Just so it matures at cone 5 or above. Low fire clay's don't cut it. Outdoor tiles are usually bedded in Thinset mortar, and then grouted with sanded tile grout. Neither of these things have anything to do with the spalling/cracking problem.

One of the bad things about a bad COE fit is that it may be close enough to not show up at first, and then start to crack as it ages, or after a few trips in and out of the fridge.
