Lost Wax Casting History from Ancient Times to the European Renaissance

Lost wax casting, or investment casting, is an ancient technique used to cast sculptures and other items. Direct and indirect lost wax casting are the two most prevalent methods used throughout history. 

Both methods use a wax model of the finished product, which is usually cast in bronze, brass, or gold. 

These methods will be explained in more detail below, but the main purpose of this article is to provide an overview of the fascinating and long history of lost wax casting across several continents and cultures. 

From ancient origins in the Middle East to the revival of casting in the Renaissance period of Europe, lost wax casting is an art technique that is well worth understanding and appreciating. 

Early Origins of Lost Wax Casting 

The earliest examples of lost wax casting were found at the Varna burial site in modern Bulgaria and date to 6,500 years ago. The artifacts include beads, bracelets, and other small items. 

Larger artifacts like crowns, statues, and temple items have been uncovered in Mesopotamia and Israel. Ancient civilizations in the Middle East discovered new ways to cast metal items, and lost wax casting was a common technique. 

Some of the earliest lost wax casting artifacts from this region date to 3700 BC. 

While Mesopotamia and the surrounding areas are recognized for their sophisticated metal artifacts, ancient cultures in other parts of the world also employed lost wax casting methods. 

The Dunaverney and Little Thetford flesh hooks are ancient tools that were crafted using lost wax casting. They were found in Ireland and England, respectively, and date to approximately 1000 BC. 

Evidence of lost wax casting in China and Japan appears around 200 BC. China may have adopted lost wax casting techniques even earlier than this. 

Lost Wax Casting of Greece & Rome

The cultures most commonly associated with lost wax casting are ancient Greece and Rome. Bronze statues from these cultures are some of the most admired works of art in history. 

They were achieved using direct and indirect lost wax casting methods. Direct lost wax casting was the simpler of the two and was the first method used. 

Around 500 BC, Greek artists crafted bronze statues using the direct method. This required creating a model of the final statue out of wax. A mold was placed around the wax and fired, which melted the wax. Molten bronze was poured inside the mold and allowed to harden. 

The resulting product was a solid-metal statue. While a great level of detail could be achieved with the direct method, it required a large amount of metal. Another drawback was that the wax model was lost during firing, meaning only one statue could be made per model. 

To resolve these issues, the Greeks utilized the indirect lost wax casting method for most of their later sculptures. This process created hollow statues and models could be reused again and again. 

The indirect method involved coating a clay model with wax, then covering that layer with more clay. The whole piece was heated to remove the wax between the clay layers. Molten metal was poured into the cavity left behind and once cooled, was broken to reveal the finished statue.

Utilizing both direct and indirect lost wax casting methods, the ancient Greeks were able to craft incredible statues of gods, heroes, politicians, philosophers, and athletes. 

Over the 1,000 year period of lost wax casting in Greece, artists perfected the use of bronze. This metal had a lower melting point than other options, which allowed molds to fill properly. 

Once a piece was cast, artists applied finishing touches like eyes made of glass, bone, or stone. 

Unfortunately, many statues were melted down and recycled, meaning few ancient examples survive today. 

The Romans replicated many Greek bronze statues using marble. 

Lost Wax Casting in Africa  

Lost wax casting appeared in Nigeria, Togo, Benin, and surrounding areas in the 9th century. The people groups in this area of Western Africa excelled at crafting realistic bronze sculptures such as the Tada Figure. 

This statue dates to the 13th or 14th century and was found on the Niger River bank. It is hollow-cast. 

Many African examples of lost wax casting use brass rather than bronze. Artists crafted their finished works using multiple castings. 

Lost Wax Casting of the Renaissance

The European Renaissance period is partially defined by a renewed interest in classical antiquities. The study of Greek and Roman art led Renaissance artists to experiment with lost wax casting methods.

Artists achieved complex bronzes using the direct casting method but soon discovered all the old drawbacks of the simple process. 

Indirect casting was either reinvented or revived during the European Renaissance. Evidence of lost wax casting from the 1400s suggests that the methods were only revived, but it is also possible that a complete reinvention was required to achieve the level of detail found in Greek sculpture. 

While items made by lost wax casting were popular across Europe, Florence was the center of casting during the Renaissance. Artists studied classic art and reproduced statues from ancient times. 

Smaller sculptures called “small bronzes” were popular among the wealthy and scholars. These items showed an individual’s social status and declared their sophistication and interest in the classics. 

Small bronzes could take many forms but the most popular were small figurines, inkwells, and candleholders. Although called small bronzes, many of these items were made of brass. 

While Renaissance artists commonly reproduced classic statues or drew on Greek mythology as their subjects, contemporary people were also used as subjects. 

Wealthy individuals, royalty, and politicians commissioned statues and busts cast from bronze. 

Lost wax casting continued to thrive in Europe through the 18th century. Casting went out of fashion as the industrial revolution swept across Europe.
