What is cold cast bronze?
Cold cast bronze is a casting method of yesteryear which is also known as bronze resin. The technique consists of mixing bronze powder with an epoxy resin then the mixture is applied to the inside of a silicone mould in several layers wherein a wire frame can be constructed. The mould is then filled with the blend of bronze powder and resin and left to set. Although not solid bronze, these sculptures truly have the appearance and feel of a solid bronze sculpture, at a much more affordable price.
What is foundry bronze (hot cast bronze)?
Also known as the lost wax method. A hollow wax image of the sculpture is created and coated in a thick ceramic coating which has to dry thoroughly. The wax is then burnt away just leaving the ceramic shell, where molten bronze is poured. When the mould is cool the ceramic is smashed away to reveal the bronze casting, which is then cleaned and patinated by heating the bronze with a blow torch and applying a variety of chemicals. Once it is cool it is then waxed and polished. This process is much more costly and time consuming thus this is reflected in the price of the product.
Care of your bronze sculpture
If you are keeping your bronze sculpture indoors, keep it clean by regularly dusting with a soft cloth. You can also apply a wax treatment once a year.
If your bronze is going to live outdoors, the care will depend on what sort of look you want to achieve. To maintain the lustrous brown finish, you will need to clean it regularly with water and a soft brush, and ensure you dry it thoroughly. Once dry you can apply a coating of wax all over. If you are looking for a weathered, ageing look, just keep the bronze free from dirt with water and a soft brush. The bronze will gradually take on a greener more weathered appearance.
