A mold used to form at least one branch for use in lost wax cast molding, the mold comprising:
- a. a first mold half with an interior surface having a design cavity carved therein, the design cavity configured to form the at least one branch, the design cavity having a first shape;
- b. a second mold half with an interior surface having a central recess disposed therein, the central recess having a second shape, with a first plurality of spaced apart holes disposed therein, wherein the first plurality of holes are aligned with the design cavity of the first mold half;
- and
- c. a brass insert configured for placement within the central recess of the second mold half, the brass insert having a second plurality of spaced apart holes that are configured to align with the first plurality of spaced apart holes of the central recess when the brass insert is placed within the central recess;
- wherein the first shape of the design cavity of the first mold half is different than the second shape of the central recess of the second mold half.
