What is Cold-Cast Bronze?
Know Your Bronze
When people see the word 'bronze' in the description of a statue or figurine, most automatically think bronze metal. But this is not necessarily the case.
There are 2 types of bronze; Cold-cast Bronze and Hot-cast Bronze. These terms are not interchangeable. They are both completely different.
Cold-cast bronze, also known as bonded bronze, is a mixture of resin and bronze metal powder. Sculptures made of cold-cast bronze are created by pouring the resin/bronze mixture directly into a mould.
Hot-cast bronze refers to metal that is melted at extremely high temperatures and then poured into a mould. The lost wax method of casting is a highly skilled, complex, time and labour intensive process. This, combined with the cost of the raw material (copper and tin), is why hot-cast bronze is much more expensive than cold-cast bronze.
