*Manufacturing

Glass is harder to scratch. Acrylic sheets can be supplied with a scratch-resistant coating (hardcoating) which provides extra protection. While scratch-resistant acrylic are not nearly as scratch-resistant as glass. Small scratches in acrylic can be polished. Scratched glass most be replaced.

*Light transmittance
Glass has 90% light transmission, for acrylic it is 92%.

*Gloss
Acrylic provides a softer reflection of light. Station glass and acrylic opposite each other and one is seldom in doubt about what is what. Acrylic with glass look is acrylic added a bit of color so that it even more looks like glass.
