Frosted glass
From Wikipedia, the free encyclopedia
Frosted glass is produced by the acid etching of clear sheet glass, or sand-blasting. It has the effect of rendering the glass translucent, obscuring the view while still passing light.
Applications:
- To obtain visual privacy while admitting light.
- Decorative patterns may be imposed upon otherwise plain glass by using wax or other resist to retain transparent areas.
- To distribute light uniformly in a photographic contact printer.
