Mokume Gane is the Japanese term for "woodgrained metal". It is also the name of a technique used in polymer clay.
These Mokume Gane pieces are a work in progress. Not finished yet. These have been cured and sanded with 9 different varying grits of wet/dry sand paper then buffed with old denim.
Now I am going to add a clay edging around them. Once finished they will be used in a project I am finishing today
