Yes, that's what I've done in the past.  Works fine for, oh, say, an
6" disk of 16 ga. or smaller.  To make a 10" pan  (say), you need a
14" or 15" disk.  For a shallow 36" diameter bowl, somewhere around
36" disk.  I found getting the bigger disks hot enough to anneal was
slow and tedious.  Before I do another one, I'll try to think up a
trick -- ad hoc furnace, batt tent, something -- to make it easier.
