Cork Clay 120g  

For making cores for hollow core silver pieces.

Model the cork clay, allow to dry overnight or dry in the oven, then cover with rolled out sheets of Art Clay Silver or extruded lines from a syringe.

Burns away in the kiln to leave the hollow core.

Only use with kiln firing.

Once open wrap in double layers of clingfilm and store in a ziplock bag at room temperature and it will keep for a long time.
