Lost wax casting is an ancient art. The technique was first employed by the early Egyptians but it was also independently discovered and used tribal artists in South America who used it to cast pre-Columbian gold. It was rediscovered by the great Renaissance goldsmith Benvenuto Cellini. While modern versions of the lost wax process employee a few differences, such as industrial vacuums to pull the molten gold down into the mold, the lost wax method as used today is really very similar to that employed by the goldsmiths of Egypt and the pre-Columbian tribes.
Rembrandt employs over 100 employees in their factory in New York. Rembrandt is a fully integrated jewelry manufacturer with a complete tool and die facility with in house designing and model making on site. Here’s how it works when Rembrandt creates a new charm: It all starts with a model created by hand in the model area by skilled artisans. They are miniature works of art created out of metal, wood or other modeling materials, using items such as photo’s and sketches as a guide. The original sculpture is then used to make a rubber or metal master mold of the charm. This master mold is used to male quantities of “waxes”.
A sculpture has to be made out of clay. This can be done, like David, by carving the piece out of the clay. Or it can be done, like pottery, where the clay built up and formed. Each sculptor creates work that is unique. The clay sculpture is sent to the foundry so that an exact replica can be made in bronze.
Over 1,000 years ago, artists in Greece, Egypt, and Rome used the lost Wax Casting method to create bronze statues. Though many famous bronze statues and fountains are located in public places like museums or parks, they can be recreated using the lost fusione metalli method. This allows homeowners to have a piece of history in their home or on their lawn at a inexpensive cost.

The next step is gating. The fiberglass and rubber molds are gently removed from the wax mold, leaving an exact wax replica of the clay sculpture. Wax rods, called gates, are attached to the sculpture. These gates will create channels in the final mold, which allows for the molten bronze to be poured into the mold.
The huge, rugged and headless ‘Yaksha’ of Handigaun is the earliest stone sculpture discovered in Nepal and dates back to the 1st century A.D. Some other early stone sculptures are ‘Sri Laxmi’and ‘Vishnu’ (both 2nd century A.D.), also unearthed in Handigaun.
So the next time you see a bronze sculpture, you can appreciate it more because you know how much work went into creating that wonderful piece of art. It took a lot of time, patience and love.
