Microwaving the bowl blank does basically the same thing except the
source of moisture is the wood itself. The purpose of both is exposure
to moist heat which causes the rupture of cell walls thus allowing
moisture from the wood to escape, and evaproate at a faster, and more
even rate thus lessening the chance of warpage, and/or cracking.

How long would one nuke a, say, 12" bowl?
