What is cold cast?

Some of the sculptures at Park Gallery are cold cast, but what exactly is that?  Are they bronze or aren't they?  Why is there a big difference in price?  Find out a little more about the process.

Cold casting, also known as bonded bronze or bonded metal, is a versatile and cost-effective process used to create metal-like sculptures, figurines, and other decorative objects. Unlike traditional metal casting methods that require high temperatures to melt and pour molten metal, cold casting involves combining metal powders (e.g., bronze, copper, aluminium) with a resin or polymer binder.

The process begins with preparing the mould for the desired object. The mould can be made of various materials such as silicone, rubber, or plaster. The metal powders are carefully mixed with the binder to create a slurry or paste. The proportions of metal powders to binder can be adjusted to achieve the desired level of metal content in the final product.

Next, the metal-infused mixture is poured into the mould and allowed to set. The curing process usually takes several hours to harden the material into a solid form. Once cured, the object is carefully removed from the mould, revealing a solid sculpture with the appearance and weight of metal.

Cold casting offers several advantages over traditional metal casting methods. Firstly, it is more cost-effective since it does not require the use of expensive furnaces and complex casting processes. Secondly, it allows for more intricate and detailed designs to be reproduced faithfully in the final piece. Additionally, the objects produced through cold casting are lighter in weight than solid metal sculptures, making them easier to handle and transport.

However, it is important to note that cold cast objects are not as durable or strong as solid metal sculptures. They are susceptible to breakage and may require additional care during handling and display. Nevertheless, cold casting remains a popular choice among artists and craftsmen due to its accessibility, versatility, and ability to create metal-like creations without the need for extreme heat.
