Fusing with Jewelers Cast

Accidents sometimes make the best discoveries. J.B. discovered this process one afternoon during a demonstration in casting with Jewelers Cast. He was in a hurry and instead of removing the silver model he had pressed into the cast, he left it in and heated his plate right over the model. Later as he was cleaning up, he removed the plate from the cast and saw that the model had fused to the plate he was working with. He liked this so much that it has become one of his most interesting and unique specialties in jewelry making. He found that pieces of shaped metal or wire bent into interesting shapes could be positioned precisely in the Jewelers Cast to form a pattern or figure. This technique could also be used for fusing the bezels of multiple stones all in one shot. This eliminated the need for tedious soldering. Fusing with Jewelers Cast requires all the same supplies needed for casting with Jewelers Cast.

Step One

Follow the same basic instructions for casting with Jewelers Cast. When the cast has reached the evaporated state, tap your metal pieces into the cast in reverse arrangement that you would like them to appear on the finished piece. We've achieved best results when the metal pieces are pressed just deep enough so that their surface is slightly above the surface of the sand. This will ensure that they contact the molten metal to fuse properly. It is also possible to press and remove a model as you did in casting with Jewelers Cast. You may also choose to give the surface area of the Jewelers Cast a texture using a rough object or spatula.

Step Two

Follow steps five through seven of the instructions for casting with Jewelers Cast. J.B.'s method of prepairing a piece of plate prior to casting, works best when fusing. If you use your torch to harden the surface be careful not to melt your metal pieces enough to disfigure them.
