Several readers have asked what happens to the wax model after I carve it.

Once the wax model is approved, the model is sprued onto a rubber base. The sprue will act as a channel for the metal to flow into. The model, once attached to the rubber base is placed within a crucible and investment (like plaster) is poured into the form. It is air dried then placed in an heated kiln for several hours until all of the wax burns away. The metal is melted then poured into the cavity inside the plaster.

Once the metal is cooled the investment is broken away and the cast item is ready to be finished. In the following pictures you will see the model without the sprue.

Next step is to finish and set the gemstones. See our next post.
