As far back as 1978-80 I worked with quartz crystal. We used Varian wafering machines, lapping machines, K.O. Lee grinders, etc. to slice, lap and round all manner of diameters and thickness of quartz wafers for use in electronics. I still remember a blank that was .077 thick (in inches) would wind up being used in a 1 Megahertz chip.
The amazing thing here, to me, is that after spending that effort to grow the crystal, it seems like somewhere near 25-30% of it is lost as granules removed during cutting (kerf, grinding, polishing, etc)

thats really cool

How much would one of these crystals cost fresh from the autoclave?
can I order custom made crystal? say like 40x1 diameter? polarized with + and - side on the sheet?
Yes, how many would you like?
Super! Thank you very much!
This is what's called "informative".
Was expecting much higher temperatures.

Just lose the music, it's out of control, anyway and sounds terrible.
