When the laser beam touches the glass surface, it heats up and the glass molecules scatter. If the glass cannot cool down, the potholes generated by heating will become larger and larger, and the final carving effect will be as bad as rotten mud, especially high-quality glass. Because the glass does not have a fixed melting point, we need to disperse heat to dissipate or reduce the heat reaching the glass, so that the glass can avoid cracking.
1. Use laser masking tape
2. Wet tissue (should be laid flat without bubbles, otherwise there may be problems with the carving at the bubbles)
3. Wet paper
4. Detergent
These four materials are commonly used and easily obtainable in daily life. After laser processing, the adhesive tape will leave mucus, and we can use wind oil essence.
Use a magic eraser, cloth, or towel to clean.
Attention: It is wrapped around the laser contact surface, and the inside of the package is completely useless
