Definition of 'Bonded Bronze'
A mixture of bronze power and resin that is used in sculpture making. In bonded bronze sculpturing, the mixture is poured directly into a mold without the use of the more traditional wax casting process that uses molten metal (referred to as hot cast). Bonded bronze is also called cold cast bronze.
Investopedia explains 'Bonded Bronze'
Bronze, which is primarily composed of copper, can be an expensive material to work with as copper prices increase with world demand. The bonded bronze technique helps reduce the cost of a sculpture by bypassing more expensive steps, but also produces a sculpture that is less durable.
Bonded bronze is a relatively new technique, as it uses materials that were not available to many artists who created bronze statues in previous centuries. Collectors tend to consider bonded bronze sculptures to be less valuable than traditional cast bronze.
