I think no matter what you're going to have to do some tuning once it's fired. I guess the big question is whether you just need it to be in tune with itself from note to note, or if you need it to be in tune with A440. If just with itself, then if it's in tune when leather hard it should be in tune when fired. If you need it tuned to A440 you'll definitely have to do some work after firing. Just remember that you won't be able to add clay to bring it into tune. You'll only be able to remove clay by drilling or grinding. But cone 6 clay is not that easy to drill or grind. Wet drilling or grinding is best, so the piece doesn't overheat and crack.

I have found that the same hold time doesn't always give the same results at all cones. 15 minutes won't always give one more cone. It could also be that cone 5 or cone 6 is not calibrated.

I've had 11 TS wheels in my studio for 9 years, and the switching thing has never been an issue. I can't imagine there's never been a time when the direction wasn't switched with the power on.

Any dark clay will darken the glazes. You'll have to either find glazes that work well with dark clay or switch to a white body. As for application, brush on 3 coats in alternating directions.

A highly polished surface will dull when it is fired.
