Had my first bash at working with Jet today. The pieces of Jet over 180 million year old were sourced from local beaches along the Yorkshire coast. An interesting workshop. A very different material to work with than my usual ceramic or plaster, will definitely be trying it again. The brooch I made today was a little cruder than I had intended, ran out of time, might try to finish it at a later date when I have the necessary polishing materials to hand.
