These are examples of prototypes of dog charms still in the wax phase of lost wax casting. The dog face has hidden connections for use as a charm or link. The pug is two sided and will have a jump ring added to it. The next step in this stage is burnout in a kiln and then metal is cast into the mold left behind when the wax disappears. This type of model would be an original prototype for reproduction for a jewelry line.
