What type of glaze do i use to preserve acorns for jewelry?

Question

I want to put a coating of glaze on a acorn pendant what type should i use?

Answer 1

Dip them in Resin ;)))

Answer 2

You can use any type of polyurethene but I recommend the marine finish that they use on boat decks and rails.  It's more expensive but it doesn't yellow and it stays on well.
