Re: Heat treating Tiger Eye.
Dear Mr. Perrin,
I would agree with Bob on that ...for years, the ring I wore had a (20 x 15 rectangular cut) heat-treated red tigereye that I had in a cast iron pan on the (gas )stove top..... low heat for long time 350 sounds OK..... ..about 3 - 5 hours... the sand sounds like a sensible way to minimize thermal shock, and not open up existing micro-cracks.
Like a good burger, you have to start with a quality base ...
P.S. I have tried this with the "iron-ny" agates in Jamaica ...no change ...(maybe a more intense heat is needed ??)
