Why are bronze statues so expensive?
Creating bronze sculpture is very expensive. Foundry charges alone can be more than half the value of a finished artwork. This does not even include the initial investment by the artist in both time and materials. Much of an artist’s expense goes into many of the steps before the artwork ever makes it to the foundry.

Does bronze last forever?
#1 – Bronze Headstone Material Some cemeteries require you to purchase a flat bronze marker. Bronze markers are made in a foundry using an alloy made up of 80% copper + 20% metal that lasts for a very long time. It is thought that today’s bronze memorials, which are much better quality, will last virtually forever.
How can you tell if it’s brass or bronze?
Perhaps the best way to distinguish between brass and bronze is through their color. Brass usually has a muted yellow shade, much like dull gold, which makes it a good material for furniture and fixtures. Bronze, on the other hand, looks almost always a reddish brown.
Is Bronze hard to machine?
A metal that is more difficult to machine is given a rating below 100%, which is the case with both bronze and brass. There are some alloys developed specifically for machining (e.g. brass alloy C360), but most copper alloys are too ductile to machine. Both bronze and brass come in many shapes, sizes, and compositions.
Does bronze turn green?
All bronze is an alloy, or a mixture of metals comprised of mainly copper mixed with other metals, usually tin and zinc. Bronze will oxidize when exposed to air, developing a patina coating. A brown, black, red or blue to green coating on bronze is a sign of normal, harmless corrosion.
Is Bronze bad for your skin?
Because of the copper content in bronze, sometimes wearing bronze can cause your skin to turn green where it touches the metal. This occurs when the metal reacts with your sweat and body oils, creating copper chelates which is absorbed by your skin. This green staining is not harmful to the skin, nor is it permanent.
What happens when bronze gets wet?

How can I tell if my bronze is antique?
If you’re looking at an old bronze, you should see a patina; a film that forms on the surface from reaction to the air. 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.
How long does bronze jewelry last?
Bronze and brass are durable, easy to clean, and will last for decades with proper care. They are great options for beautiful and affordable jewelry. One thing to keep in mind, the copper content of these metals can oxidize in combination with skin oils, creating a greenish layer of copper carbonate on skin.
How long does it take bronze to Patina?
Today, many foundries actually acid-etch the metal, to give the effect of antique verdigris. How long does it take for bronze to get verd? In direct sun, un-maintained and exposed to the weather�. more than of 5-10 years and slightly shorter on the beach with salt water spray.
How do you age bronze quickly?
Mix an aging solution using equal parts lemon juice, household bleach and distilled vinegar. Add 1 tablespoon of salt for every 6 ounces of solution you make, as an abrasive. For example, if you mix 4 ounces each of the three liquids, making 12 ounces total, add 2 tablespoons of salt.
Does Bronze scratch easily?
The development of patina is a natural process in all bronzes. Bronze is a combination of copper and tin, and it was the first metal alloy used extensively in human civilization. Bronze patina is hard and can’t be scratched off easily, and forms a stable surface layer that resists further oxidation.
