You can use V pendant inserts for making pendants, and grooved cabochon mandrels inserts which make fabulous bases for wire wrapping, though can be used with simple round cord around the outside, as well. Buy more handles and inserts as you need them! The handle is a 1/4" diameter tube of stainless steel. Different inserts can be placed in the top, then lock them in place with a screw. You can put the whole thing in the kiln for annealing. Handle length of 10". This handle arrives alone, for customers who already have several inserts, and would like to make more then one option per session. You can not buy multiple handles to use the same inserts in a torch session, as the inserts need to stay with the glass piece throughout the kiln process.
