A friend gave me several bowl blanks that she'd bought online... They
are all dipped in wax, as opposed to the ends coated...

I turned on and it was very green and wet... Cracked as I was tuning
it!

I'm considering scraping the wax off of everything but the ends, to
let it dry normally, any reason that I shouldn't??

I'm thinking that completely sealed in wax, they'll never dry, am I
wrong here?
