Lynne,
As a full time dental technician, we are the people who make the crowns for
the dentists, I can say with certainty that those "ovens they fire porcelain
in" are anything but cheap! Unless you consider $5000 for a chamber that is
less than 4x4 inches, of course they fire under vaccuum. Sorry to
dissapoint you, but your best bet is a small test kiln from a pottery
supplier.

ps. those little kilns usually have a top temperature of 2000 degrees F, as
most dental porcelains are vitrified at 1800 degrees F
