Just click on the photo to enlarge it and see the details.
The cutter and owner of the oven told me that he had been babysitting his young daughter at his place of business, and when he got ready to leave, someone stopped him to talk while he was walking out. His daughter was behind him, and was eye level with the dial on the oven, which she must have turned to the right, up to well over 700 °C, and so the blue-green tourmalines he had cut were cooked from Saturday afternoon until Monday morning.
Note that the stones were cut and polished before heating, just like the ones in the photo that were not over cooked. Another dealer told me that if the stones are not polished before heating, in which case the surface is not smooth, then during heating the stones can acquire a coating that cannot be polished out.

Wow...it's painful to see that, but it's also a bit fascinating to see the transition.
ReplyDeleteThe owner of the oven sure was taking it well -- I was surprised.
