Our process

When you, the artist, bring in your sculpture we look carefully at the complexities of the piece and then decide how to create the mold. Sometimes this requires separating the piece to cast it into sections, however with new advances in mold making technologies we are able to create very complex molds, which enable us to keep your original intact.

 We work closely with our artists throughout the process and will discuss your specific needs for finish and patina. Artists are welcome to be involved as much as they like while their work is being created. Many of our clients stop by to add final detail to the wax before it is invested, as well as to inspect the metal casting before the patina is applied. Image 
 After the mold is finished we create a hollow wax replica of the original. Into the mold we pour molten wax in layers. When the wax cools it is removed and our staff of artists remove the seam lines and repair any discrepancies.

Once the piece is reworked to your standards it is “gated and sprued” with wax rods that are attached to the piece and fed to a wax cup. These rods will eventually provide cavities in the ceramic shell mold and these channels will allow molten bronze to flow into the piece.

The sprued and gated duplicate is repeatedly dipped in a liquid ceramic slurry until a suitable thickness is built up around the wax producing the shell mold.

When the shell is completely dry and hard it is put into a furnace and the wax duplicate is melted out. At this point the ceramic shell mold is ready to receive the molten bronze.

 “Pour Day” is sometimes referred to as a carefully choreographed dance. Every aspect of the pour is meant to promote the safety of our staff and the quality of our product.

We source the finest silicon bronze available so we can deliver the best surface quality and detail to your work.

The ceramic shell mold is heated until glowing red-hot, and then pulled into the “pit” where the bronze is carefully poured at temperatures of approximately 2,000 degrees.
