    Engraving oyster shell (esp. pearl oyster) with a fiber?

    Has anyone tried engraving oyster shell (esp. pearl oyster) with a fiber? They engrave nicely with my CO2 lasers but a friend (who wants to engrave shells among other things) is trying to decide between CO2 and fiber.
    Longtai 460 with 100 watt EFR, mostly for fun. More power is good!! And a shop with enough wood working tools to make a lot of sawdust. Ex-owner of Shenhui 460-80 and engraving business with 45 watt Epilog Mini18.

    I've never tried it but the general rule of thumb I've always heard was if it's organic, the fiber doesn't like it. I'm sure there are exceptions to that, like what frequency your fiber is capable of but it's worked pretty well for me. In general, wood, paper, stone, etc, don't really do well with the fiber so I'd assume it would fall into that category and CO2 would work better.
