Here's another link to the origins of large acrylic
castings.
This is a more detailed story than my last post on
Bruce Beasley.
It is truly impressive when you look at the scale
of what he was doing
& the complex nature of it.
There's even a photo of the autoclave with North
West Native American
art on it.
This next link is a paper by Stachiw to the navy
outlining the benefits
& problems encountered with casting
domes.
