It is not a bacterial illness, but the consequence of a chemical interaction with the chlorides, which generally happens as a result of seawater contamination of the bronze item or burial in particular types of soil containing chloride ions. If the afflicted artifact is not addressed, it may be completely destroyed. However, this danger applies only to intact specimens. Bronze that has rusted can be treated in the same way as iron.
Like iron, bronze will oxidize if exposed to air and water conditions for several months to years. This natural process is called "bronzing". In general, bronzed objects are not considered damaged because of their appearance- rather they are considered to be an important part of history that should be preserved for future generations to see.
If you believe your item exhibits signs of damage caused by moisture or acidity, such as corrosion or peeling paint, contact a conservator immediately so that appropriate action can be taken to save the object.
Bronze illness is characterized by active corrosion, which means that your bronze object is not protected and is constantly corroding. This can do significant harm to your bronze object. Bronze illness is more common in locations with high humidity, salts in the air, or ammonia pollution. These factors all promote water oxidation, which leads to corrosion.
The two main types of bronzes are silver-tin and copper-zinc. Both types are very reactive when exposed to air and both need to be cared for regularly. However, tin bronzes are more susceptible to damage from acids and zinc to oxygen in the air. On the other hand, copper objects tend to wear faster but they are less likely to oxidize.
Other elements can also affect the durability of your bronze object. For example, iron oxide stains on your bronze object's surface can hide any etchings or marks that may exist. Also, heavy metals such as lead or mercury can leach into the bronze and cause it to deteriorate over time.
Finally, sunlight can fade your bronze object's color over time. Regularly apply a clear coat or polish to protect its appearance.
Bronze disease is a kind of corrosion that damages bronze objects. It appears as a powdered green residue on the metal's surface or as a warty or waxy layer on the surface of an item. To the untrained eye, it may just look like a natural patina. The residue is actually oxidized iron and copper compounds.
People often get bronze disease when they clean their bronzes with chemicals such as acid cleaners or salt water washdowns. The acids and salts in these products can cause parts of the object to lose their protective coating of oxide layers. This allows other elements to react with the metal beneath, causing it to corrode. At this point, the only thing protecting the metal is its original color. When you wipe off the powder, it drops onto your floor or clothing because it's mostly iron and copper.
If you think your item has bronze disease, call us for advice about how to treat it. We can help you determine what type of bronze it is and give you recommendations about how to preserve the piece. Bronze disease can be removed from some items if done properly. Others should be discarded instead.
The best way to prevent bronze disease is by not cleaning your bronzes with chemicals. Only use warm water with a little bit of soap to wash them. Make sure to rinse them well and dry them completely before displaying or storing them.
The response is referred to as "bronze illness" because it forms a green powder on the surface of bronze objects that resembles a fungus. This corrosion is similar to rust on iron. This corrosion is induced by a series of circular reactions involving the chlorides of a copper alloy and water. The chloride ions are produced by chemical compounds in sweat that dissolve into liquid form when heated to produce steam. The resulting acid reacts with copper to create more soluble chloride salts.
Bronze objects should not be exposed to direct sunlight or any source of heat or humidity such as a radiator. They should also not be immersed in water because this will cause damage to the metal itself.
If you own a business that uses brass, then make sure that you clean all surfaces that come in contact with it regularly. Use a brass brush to remove any dirt or oil that may have accumulated. If there are areas that don't get cleaned regularly, such as door knobs and light switches, then these items should be replaced periodically so that other parts of your business aren't being damaged by unclean equipment.
Brass is a term used to describe an alloy of zinc and copper. It is usually used for pipes and kettles because it has good heat-resistant properties. But like any other metal, it can become corroded if it isn't treated properly. Corrosion can be caused by acids from natural sources or chemicals from industrial processes.
