Based on Scottish prehistoric cup and ring markings carved by ancient peoples in the bed rock of Argyll and other places these pieces (4) were made for an exhibition in a local museum. I haven't done a great deal of off centre turning but after a little thought and the discovery of some lead under the caravan (counter weight) I thought I would have a try The surface is a combination of blow torch, fuming and oil. After completing this I took it to photograph where I realised just how many variations you can arrange the 4 pieces to make numerous different shapes.
