Types of frosted glass:
Acid etched glass allows for complex, intricate patterns to be etched into the surface while leaving other areas transparent.
Sandblasted glass has a uniform opaque appearance, due to the even roughening of clear sheet glass. This process allows the window to still admit light while blurring visibility.
Adhesive vinyl decals can be used to create any combination of full-color and clear glass images surrounded by opaque vinyl, mimicking the frosted glass effect without permanently altering the surface.
