Microscopic surface analysis and contamination details

Before Treatment

When we examine ebony's contaminated surface up close, grime layers coat every crevice and dull the natural sheen. Dust particles cluster in uneven patches, making the texture look rough and clogged. Scratches from wear hide beneath this buildup, obscuring the wood's fine details.

After Treatment

After laser treatment, we've found the surface gleams smoothly with no residue left behind. The clean texture reveals sharp grain lines that run evenly through the material. Polished areas now shine uniformly, bringing back

FAQs for laser cleaning Ebony

Common questions and expert answers about laser cleaning this material
How do I prevent burning ebony during laser cleaning?
You must start with lower power settings to gently remove surface dirt without overheating the dense wood. Ebony's hardness helps it withstand the process, but its low heat tolerance means you should use short pulses that clear buildup quickly. Keep the laser moving steadily across the surface to avoid hot spots. In my experience, this approach restores the natural finish beautifully. Watch out for prolonged exposure, as it can char the material and ruin your work.
What's the best practice for cleaning old dirt off ebony artifacts?
Make sure you test the laser on a small hidden area first to see how the ebony responds. The wood's tight grain absorbs energy evenly, so a focused beam works well to lift grime without scratching. You'll want to follow up with a soft cloth to polish away any residue left behind. This method preserves the ebony's deep color and smooth texture effectively.
