I obtained some stones that although beautiful, are soft and have a
high amount of grit so I’ve been advised against polishing them. When
I said I wanted to make pendants from them (probably with wire
wrapping), the proprietor where I got the stones from recommended
coating them with polyurethane so the stones wouldn’t wear down as
someone wore them.
My questions to you are:
Is there a specific type of polyurethane you would recommend for
Is there a specific number of coats I should apply?
Is there a specific method of application I should use? If yes,
please describe it.
Thank you so much for your time.
