Ron,
I am retired but loved my former technical work, so please do not take my comments the wrong way. You may get more questions than you expect and I am not trying to be difficult, but you have made comments that make me almost want to go to work again. But not quite.
Who is Mike Blue and what is his background? I can PM him but he might take such a query, out of the blue, the wrong way. I do not want to offend anyone.
What's an 'ites class'? Does Howard Clark do materials science? What did he use to see reduced grain structures? That usually takes an electron microscope.
My apologies sir, you have stirred my curiosity and just tell me to go away and I will!
Cheers, Steve
