Need help finding a chart or on heat treating sapphires.
Does anyone know of a website or other location where I could find
this info?
Thanks, Wally
Dear Wally
Ted Themelis’ book “The Heat Treatment of Ruby and Sapphire” is
maybe what you are looking for:
Also check out the article:
“Heat Treating Sapphires from The Anakie district, Australia.”
Last, make sure to pay a visit to Richard Huges’ website
