Covered with a thin layer of ice crystals, or having a translucent, textured surface treatment.
From Old English 'frost' + '-ed' suffix. The word evolved from describing natural ice formation to artificial treatments that create similar visual effects, particularly in glassmaking and food decoration.
Frosted glass represents humanity's attempt to harness one of winter's most beautiful phenomena and make it permanent. The technique transforms transparency into mystery, allowing light through while maintaining privacy - it's democracy for windows, giving everyone the benefits without the full exposure.
