A bronze sculpture, often simply called ‘a bronze’, is a three-dimensional piece of art made by pouring molten bronze into a mould, before leaving it to solidify. Bronze is an alloy of copper and tin, made by heating the two metals together and allowing them to cool.

What is cast bronze made of?
Bronze is an alloy that is traditionally made up of copper and the metal tin. The ratio between copper and tin varies from one metal to another, however, recently, one can only be considered bronze if it’s made up of 88% copper and 12% tin. Liquid bronze is created by melting copper and tin and mixing them.
What is inside bronze?
Bronze is a metal alloy that primarily contains copper and 12% tin. Other elements—such as aluminum, arsenic, manganese, phosphorus, and silicon—are also added to yield different properties. These mixtures form some of the common bronze alloys, including: Leaded bronze.
What is cast bronze resin?
COLD CAST BRONZE Also referred to as bronze resin, this technique involves blending bronze powder with polyester resin to produce a material which is applied to the interior of the silicone mould. Subsequent applications of this will produce a shell into which an armature (wire frame) can be constructed.
Are bronze statues solid or hollow?
Small statues were directly sculptured in wax, so that when it is invested (covered) with clay and the wax melts, the interior is completely hollow, so the bronze statuette is solid.
How are bronze sculptures made?
A bronze sculpture, often simply called ‘a bronze’, is a three-dimensional piece of art made by pouring molten bronze into a mould, before leaving it to solidify. Bronze sculpture is made via a process known as casting: pouring molten metal into a mould and leaving it to solidify.
What is casting in sculpture?
Casting: Sculptures that are cast are made from a material that is melted down—usually a metal—that is then poured into a mold. Casting is an additive process. Modeling: Modeled sculptures are created when a soft or malleable material (such as clay) is built up (sometimes over an armature) and shaped to create a form.
How do you cast bronze sculptures?
The Process of Bronze Casting
- Once the sculpture is complete, it is then divided into sections.
- A flexible rubber mold is made from the artist’s original clay.
- Molten wax is then poured into the rubber mold, producing a casting of the original 3D.
Does bronze contain zinc?
There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin. Commercial bronze (90% copper and 10% zinc ) and architectural bronze (57% copper, 3% lead, 40% zinc) are more properly regarded as brass alloys because they contain zinc as the main alloying ingredient.
How can you tell if a sculpture is bronze?
One simple test is to apply a magnet to the artwork and see if it sticks there. Iron is highly magnetic, and you’ll feel the pull in the magnet. If you set a magnet on bronze, it’ll fall off. Also, watch for patches of corrosion, because bronze doesn’t rust.
What is the difference between cast bronze and bronze?
Bronze Resin sculpture also known as “cold cast bronze” or bonded bronze, is made of real bronze powder, mixed with polyester, epoxy or another resin and poured into a rubber reusable mould. Casting a cold cast sculpture is faster and less expensive than casting bronze.
What is alloy of bronze?
bronze, alloy traditionally composed of copper and tin. Some modern bronzes contain no tin at all, substituting other metals such as aluminum, manganese, and even zinc.
Does bronze turn green?
Bronze is an alloy that contains copper, which can oxidize when combined with moisture, creating patina. This reaction creates that green tint of copper carbonate on your skin after wearing a piece for awhile. This discoloration happens most often with rings, due to the close proximity of skin to the bronze.
