Wax has been utilized in sculpture making for thousands of years. It's a versatile and accessible material, and it's useful in a variety of sculpture techniques, including modeling, casting, and as part of the lost-wax casting process.
Wax is often used for direct modeling of sculptures. Beeswax is commonly used, often mixed with other substances to make it harder or more workable. The wax can be molded when warm and firm up as it cools, allowing for fine detail and texture. Because of its flexibility and ease of use, wax is excellent for capturing intricate details and creating small, delicate forms.
Wax is often used in casting, especially in the lost-wax casting or cire-perdue technique. This method is commonly used for casting metal sculptures, especially bronze. The process involves several steps:
- Modeling: The artist creates an original model of the sculpture in wax.
- Molding: The wax model is then coated in a heat-resistant material, such as clay or plaster, which is allowed to dry. This creates a mold of the sculpture.
- Burning Out: The mold is heated, which melts the wax, leaving a hollow space in the shape of the original sculpture. The wax is "lost," giving the process its name.
- Casting: Molten metal is then poured into the mold, filling the space left by the melted wax.
- Breaking the Mold: Once the metal has cooled and hardened, the mold is broken away, revealing the finished sculpture.
Wax in the History of Sculpture
One of the earliest known uses of wax in sculpture is in the form of beeswax used for casting bronze items in ancient civilizations, including in Egypt and the Near East, over 5000 years ago.
In the Middle Ages, wax was commonly used to make death masks and effigies of notable individuals. During the Renaissance, artists like Leonardo da Vinci and Michelangelo used wax models as part of their sculptural process.
Some artists make sculptures entirely out of wax. These sculptures can be extraordinarily detailed and lifelike. Wax museums, like Madame Tussauds, display wax figures of famous individuals.
Wax sculptures require specific conservation conditions. They are sensitive to heat and light, which can cause the wax to soften, deform, or fade. Therefore, wax sculptures must be stored and displayed in cool, low-light conditions.
In conclusion, wax has a long history and significant role in sculpture making. Its versatility, accessibility, and capacity for fine detail make it an ideal medium for both direct sculpting and casting processes.
