ROFL! That happened to me when I was working for an asshole about a
decade ago. I was designing with Philips (now NXP) mcs51 processors,
and he was convinced that I had no idea of what I was talking about. He
called Philips behind my back, and asked them a bunch of questions.
They told him they knew a guy local to him that was really good with
those processors, and would likely help him out on a consulting basis.
They then gave him my phone number. ;) Boy was he pissed.
But about glass plate holography...On a list I run, a few people are
doing a type of holography involving gelatin, DCG holograpy.
(DiChromated Gelatin) Some of the guys are doing some pretty impressive
work. They're using glass plates, coating them themselves.

Does anybody
still do the very early photographic glass plates?
about 35 years ago, a friend of mine was doing sandbox holography. She
went in to Alpha Photo in Oakland, which was one of the few real
professional supply houses, where she bought her supplies. They had
different glass plates than she was used to using (dimensional stability
was too critical for film), so she asked about their suitability for
holography. The clerk said, "Don't know. But we have a customer who is
really expert about that, and I'll find out!"
When she got home, there was a message on her answering machine.
"Hello, this is Mike from Alpha Photo. We have a customer who wants to
know about glass plates for holography, . . . "
