Tempered Glass Laser Cleaning Settings

When laser cleaning tempered glass, we've found it behaves quite differently from standard annealed glass, which handles heat more evenly without the built-in stresses. Tempered glass's surface compression makes it incredibly strong against impacts in applications like automotive windshields or architectural panels, but that same tension inside means it can shatter completely if heat builds unevenly during cleaning. This sets it apart, so we approach it by using gentle, controlled passes to distribute energy without triggering those stresses—think starting slow to let the laser clear contaminants like oils or residues from electronics manufacturing without risking fractures. Its low heat spreading ability helps absorb the beam effectively for quick surface restoration, especially in delicate spots like medical devices or solar panels, but you must watch for hot spots that could propagate cracks. In our experience, this targeted method brings back clarity and shine reliably across marine or cultural heritage uses, preserving the material's durability. Just remember, always test on a small area first to avoid sudden breakage from overlooked thermal buildup.
