Post subject: | Re: Composite Ruby - Lead glass treated Ruby |
The question is not about the labs and others identifying LGFR/composite ruby early on, and not really about greed although it is absolutely true that greed is the gas in the engine here. I'm truly wondering why no one has seriously questioned it's title of "ruby" right from the gate 7 years ago. I think the Labs did what they were suppose to do nearly from the start, they may have been a little late in seeing the complete instability (my opinion) of the material, but other than that they were right on. The chemistry is there, (although a copious amounts of additional chemistry Pb-glass, has been added too) the basic "un-heated" inclusions are there when not hidden by the glass, the RI is there, the hardness is there in spots ![]() |
