I'm new to lampworking and have an annealing kiln ordered. In her article
in Lapidary Journal on setting up a beadmaking studio, Cousette Copeland
says, "If you use vermiculite, you must kiln anneal your beads within 9
days". I have a bunch of beads here that are several weeks and months
old. Should I pitch them? What's magic about 9 days? From the
explanations about annealing that I read, I don't see why they couldn't
be annealed at any time if they are not cracked. Please enlighten me.
