The uneven edges or lines left on glass after laser engraving can dramatically alter the final appearance.
You can, however, take certain actions to make the glass look better and smoother.
Firstly, gently sand away the rough parts using a piece of fine-grit sandpaper.
After that, you can gently buff the glass to a smooth finish with a polishing product and a soft cloth. You can use a glass polishing machine to achieve a more polished look.
You may increase the beauty of your glass engraving with a smooth and polished finish if you use the correct tools and procedures.
