Terracotta Settings

When laser cleaning terracotta, watch out for its porous nature right from the start—it can trap heat unevenly and lead to cracks if you're not careful. I've seen this happen when folks push too hard too soon, so begin by testing a small area with gentle pulses to gauge how the surface responds. This material tends to absorb laser energy moderately well, which helps remove dirt and grime without much effort, but its low heat spreading means you should keep dwell times short to avoid localized overheating. Move to a multi-pass approach next, starting low on power and building up only as needed. Terracotta's relative fragility compared to denser stones calls for wider scan overlaps, ensuring even coverage without stressing the structure. What sets it apart is that baked-clay makeup, so it cleans up beautifully for heritage pieces but demands you pause between passes to let it cool. Avoid high speeds early on; slower ones prevent surface pitting. In my experience, this setup preserves the earthy texture while stripping away years of buildup safely.
