Laser Engraving Cork 

Cork is a material that is particularly well-suited for laser marking. The nature of the material allows a very good contrast to be achieved with even low powered lasers. A common method of processing cork is to cover the surface with masking tape prior to lasing. This eliminates any burning on the edges of the mark and greatly increases the quality.

It is not recommend that the laser be used for cutting cork however. The edges tend to be a little rough after processing.
