Ultra Clear Glass is well know as super clear glass, super white glass, low iron glass whose light transmittance reaches 91% or above.
Frosted Glass Pieces
Frosted glass is produced by the sandblasting or acid etching of clear sheet glass. This creates a pitted surface on one side of the glass pane and has the effect of rendering the glass translucent by scattering the light which passes through, thus blurring images while still transmitting light.
