Hot Cast Bronze Process
All of our bronze sculptures are genuine bronze metal made using the hot cast method.
The difference between the hot cast and the cold cast method
It’s actually very simple.
Hot cast is metal and cold cast is resin.
With Hot cast sculptures (like all of ours) the sculpture is actually made of molten metal. Cold cast bronze is made from a polyester resin blended with bronze powder for colouring so they are not actually bronze at all and should not be allowed to be called bronze as this causes the consumer considerable confusion.
Of course cold cast bronze sculptures are plastic based and far cheaper to produce but they are not bronze. All of our bronze statues are real bronze and as we supply direct from the manufacturer we offer exceptional prices that are often similar in price to the vastly inferior cold cast method.
The hot cast method of bronze sculpting
Bronze does not occur naturally, it is in fact a combination of copper and tin. It combines to create a very hard and long lasting material that has been used as far back as 3000BC. The methods used today to create a genuine bronze sculpture remain much the same as it did then!
Bronze sculpting is known as the lost wax method. It is a many stage process that is labour intensive and time consuming. That is also why bronze sculptures are usually far more expensive than the cold cast resin substitutes.
The original sculpture is made from a hard material, this could be wax, clay or even plastic.
A mould is made of rubber that exactly replicates the original sculpture so duplicates can be made.
Moulten wax is then poured into the mould to form an exact wax copy of the sculpture and this can then be hand finished to remove any imperfections
The wax copy is then coated with ceramic.
This takes several days and many layers are added and then kiln fired to harden.
This process also melts the wax and that is why it is called the lost wax process. What you have then is a ceramic mould that the molten bronze can now be added to.
The molten bronze is poured into the cavity and allowed to set.
When fully set the outer ceramic shell is broken to reveal the bronze sculpture. The bronze sculpture is then hand finished by sanding, sand blasting and polishing to reveal an exact copy of the original.
Finally a patina finish is created by using chemicals and then heated to bring colour and shading to the sculpture.
All of this is completed by hand
There are no machines used in this process, just the keen eye of the bronze craftsmen.
Finally it is ready to grace your home and with a little care and attention will last several lifetimes.
