In Finland the kuksamakers boil them in saltwater, that takes the tension out of the wood. Otherwise the kuksa might crack when filled with hot liquid. And they are not supposed to be coated with anything.
And a kuksa shall never be washed or even rinsed after use.

I read about this saltwater boiling but didn't fancy tea or coffee tasting of salt for months after. I watched a YT video in which the guy wrapped his kuksa in paper, really tight like a mummy. Then put it in a shoe box, more paper into the box and then let it dry. I did that and apart from a few very small cracks it really worked!!!
 
The idea in the salt treatment is to get some salt into the wood, salt is hygroscopic so it keeps the wood moist and not cracking. There are other possibilities like keeping it in acetone or MEK for a few weeks. Or treating it with very strong acetic acid.
