No, placing glass in the freezer will not create the frosted effect you're thinking of. While glass can develop condensation or a "foggy" look when chilled in the freezer, this is a temporary result of moisture in the air condensing on the cold surface, not actual frosting. Key Differences: Freezer Effect: When glass is placed in the freezer, it will become cold, and moisture from the air will create a frosty or foggy appearance. However, this effect disappears once the glass warms up, and the moisture evaporates. Frosting/Etching: True frosting or etching is a permanent alteration of the glass surface using a chemical etching cream, sandblasting, or frosted spray paint. These methods physically change the texture of the glass, creating a long-lasting frosted look. So while you might get a temporary frosty look in the freezer, for a permanent effect, you'll need to use proper frosting techniques like etching or spraying.
