====== Acrylic glass ======
[[Watch]] glass

Acrylic glass (also //Plexiglas, synthetic glass//) consists of polymethyl methacrylate (PMMA) and with its 3-4 [[Mohs]] is less scratch-resistant, but quite unbreakable. Scratches can be polished out with a special acrylic polishing paste. From this material extremely arched (domed) watch glasses can be produced quite easily.
