How expensive is bronze casting?
The process, from the creation of the mould to the casting until the patinating and finishing touches, requires several labourers. Bronze sculptures also take months to get done depending on how complicated and large it is. So if you want one made, be ready to spend around $10,000 to $100,000.
Is cold cast bronze valuable?
Casting a cold cast sculpture is faster and less expensive than casting bronze. It is also much lighter and is still relatively strong, as it can be reinforced with an internal steel structure.
How can you tell if a cast is bronze?
If it flakes or scratches off easily, it’s probably a painted on patina-substitute. Scratching the patina also shows the surface of the metal underneath. Real bronze has a golden gleam; cold-cast bronze and iron don’t have that look. You can also compare a suspect figure with pieces you know are bronze.
How long does it take to cast bronze?
As you will learn, the high cost of a bronze sculpture is due to the many hours of hands-on-labor involved. Once the clay sculpture is completed by the artist, the entire process in the foundry takes from six weeks to four months to produce a single bronze.
Is cast Iron stronger than bronze?
Iron is not much harder than bronze. Bronze and tin are relatively easy to extract from ore, whereas iron ore requires a much more energy intensive and complicated process to smelt. Bronze can be easily melted in a pot over a fire while working iron requires a specialized furnace.
Can you break bronze?
High tin bronzes, or bronzes with a higher tin percentage, are easily stronger the iron and even some steels. Too much tin, however, can cause bronze to be too brittle and/or have casting problems, which is why the liberty bell has a crack in it.
What does cast bronze mean?
You may have heard bronze referred to as solid bronze sculpture, foundry cast bronze sculpture or hot cast bronze sculpture. All these are accurate, as they refer to metal that is melted at extremely high temperatures and then poured into a mould.
Why are bronze sculptures so expensive?
Creating bronze sculpture is very expensive. Foundry charges alone can be more than half the value of a finished artwork. Much of an artist’s expense goes into many of the steps before the artwork ever makes it to the foundry. Making copies can spread this cost out.
