Acrylic

[Mike1]

Is there a difference between *cast acrylic* and *acrylic* sheets? The person that I am buying this from only knows that they are acrylic. He bought them directly from the factory years ago and that was all he was told.
As well, has anyone tried doing litho's with coloured platic. ie: blue?
Thank you.

Cast acrylic is hardened vs the normal acrylic like Plexiglas. Dan post a test to see if it is cast or not by using a dulled bit at high speed to see if the acrylic will melt and stick to the bit.

Thanks for the reply. I will see if I will be allowed to test.
Thanks again
