It's a tradename for polymethyl methacrylate (PMMA) plastic, also known as acrylic or Plexiglass.
I tried to make Christmas presents out of it one year and failed miserably. I've still got the chunk I pried out of the bottom of the beaker three weeks after the solvent had evaporated. There's a notch in it where the magnetic stir bar was. I've got another irregular chunk with bits of wax paper in it where I couldn't pry them out of the folds. FYI, wax paper makes a terrible mould. /the more you know
