トラブル
Doping begins at the surface nucleus.
Japanese: 失透は表面の核から始まる
Clouding (white haze) begins at a nucleus on the surface. Scratches, grease, and dust can serve as nuclei. Simply wiping the surface clean before baking greatly reduces this risk.
Clouding often develops around surface scratches, grease, or dust particles.
Wipe down the rack with alcohol before baking to keep the area around it clean.
Glass itself doesn't easily lose its transparency. What triggers this is something that gets on the surface—such as oils from your hands, dust in the air, or dust from the shelf.
You can significantly reduce this by simply wiping the surface with alcohol right before baking. Be extra thorough on humid days or after using new baking sheets.
A piece that has already become slightly cloudy may be restored by reapplying the fire polish. It's worth a try.
