Acid-etched glass refers to annealed glass that has been treated with hydrofluoric acid to give its surface a frosted look. Entire sheets of glass can be acid-etched or small sections can be treated to add specific designs.

Acid-etching is seen as a great alternative to sandblasting because the finished surface is smoother to the touch and easier to maintain. The glass can also better withstand stress and stay smudge-free longer. Because of its durability, acid-etched glass can be cut into any shape or size and then tempered.
