Casting Acrylic

Was I missing something ?-- I thought the problem was casting the
acrylic as an end product not a pattern. Small acrylic items may be
vacuum diebubbled but larger pieces are pressurized in an autoclave
to collapse the bubbles. I know very little about this but if you can
find a copy of:

"Sculpture : Technique, Form , Content " by Arthur Williams
(1995) isbn 87192-277-0 In print I think

You will find a little on page 273. Pages 268-272 cover
Polyester which you may be calling “acrylic”. Some help but not
much.
