Experience of OEM glass customization factory: the patterns, characters and LOGO on the glass are customized with decals, and then after baking and cooling in a high-temperature furnace, the patterns are fixed on it, which is generally difficult to fall off, so it is difficult to scrape with a knife. Erase method: 1. If it is baked at low temperature, it is easy to remove; 2. If it is baked at high temperature, remove it with strong acid or alkali.
