How to drill seaglass

Hi Rhona - there are several keys to drilling without cracking the
glass:-

  1. keep the glass cool by keeping it under water;

  2. use a diamond drill bit (other types will barely scratch the
    surface);

  3. drill slowly - I use the traditional bow drill, although one can
    use an electric one;

  4. make sure the back of the glass is supported (for example on a
    small block of wood) so when the hole is drilled through it doesn’t
    chip on the reverse. Even better, drill half way then reverse & meet
    it the other way.

Hope that all makes sense. Works on enamels too!
