I want to make a vase on the lathe, and I also want it to hold water. I don;t know what finish to use because I don't know what would last. I know water on bare wood like that would cause warping or mold, something. What can I do to 'water-proof' a wood vase?

Also I do not have a specific wood that I am thinking of using.

    I would think you'd want to use a heavy film finish, like a "bartop" finish or epoxy/CPES. Also worth thinking about is finishing the inside differently than the outside if you don't like the "plastic" look of a heavy film. – SaSSafraS1232 Sep 7 '17 at 17:23
  • @Graphus I don't mean to have duplicated any other question, I did not notcie them when I was looking. And thanks for the resources! Looking at the one answer you have wrote, oil-based polyurethane would work? – Ljk2000 Sep 7 '17 at 18:43
  • If you apply it thickly enough yes, it's waterproof. But no guarantees how long it'll hold up so if you want a long service life consider other options. – Graphus Sep 8 '17 at 5:41
