The difference between real bronze and cold-cast or bonded-bronze
Foundry bronze is the traditional method of casting bronze using molten metal that is melted at an extremely high temperature and poured into a mould.
The same techniques of casting have survived many centuries and have changed very little. This method is called the lost wax process and is a highly skilled, labour intensive process.
Cold-cast bronze or bonded bronze is a resin that has bronze powder added to give the appearance of bronze.
The casting process is much simpler and faster and therefore less expensive.
