Advice needed. I sanded the tops of these kiln dried rounds and then coated both sides with shellac. Most of them split a few days later.
The untouched rounds have been stable.
How can I make these smooth and shiny and keep them intact?

I'm going to experiment a bit.
While you're at it, maybe plane or scrape a couple of rounds, too. If sanding marks and raised grain really do increase the exposed area, getting rid of them will reduce it.
I would think someone out there has already done the experiments, but I didn't find anything with a quick look.
Also, if you're not committed to shellac, there are coatings that are less permeable to water vapour.
