There are two commonly used solvents for welding acrylic (PMMA) that
I am aware of: chloroform and methylene chloride. So far I have only
used chloroform (with a bit of acrylic dissolved for a filler. The
crazing that accompanies the use of solvents appears to have something
to do with the stress that the material is under. I have found that
MOST sheet doesn't craze but that most pipe does.
