Bronze sculpture is made via a process known as casting: pouring molten metal into a mould and leaving it to solidify. Casting is a very different technique to the chiselling and carving associated with marble sculpture, or the modelling associated with ceramics, but is used to achieve the same effects as both.
How do you make a bronze sculpture step by step?
Making a Bronze Sculpture STEP 1: Make an original sculpture. STEP 2: Make a wax copy of the original sculpture. STEP 3: Make a mold for the bronze using the wax copy. STEP 4: Make the bronze. STEP 5: Patina and mount the bronze.
What are the three steps in making a bronze sculpture?
How Bronze Sculpture Awards Are Produced Step 1: Create a Model. Step 2: Create a Mold. Step 3: Create a Wax Replica. Step 4: Prepare the Wax Replica for Casting (Spruing) Step 5: Coat the Wax with a Ceramic Shell (Investment) Step 6: Burn Out the Wax (Burnout) Step 7: Pour the Bronze (Pouring).
What sculpture technique is used to make bronze sculptures?
Bronze statues come to life differently than marble statues. Instead of carving a block or marble, the bronze artist uses the lost-wax technique to make a series of molds, and then pours melted bronze into the final mold to create the sculpture. This method has been around since 4500 BCE.
How much does it cost to make a bronze statue of yourself?
Now, if you want a bronze sculpture made of yourself. I would expect at a minimum $40,000+. More if you want a known artist to make it. And more if you want it to be a perfect likeness.
How can you tell if a sculpture is bronze?
It is possible to make a test to distinguish bronze from regulus, in fact, if you discretely scratch a part of the statue with a metallic object and a yellowish tint appears, the object is made of bronze. However, if by doing so a colour verging on white appears, it is likely made of regulus.
Can you cast bronze at home?
Knowing little about casting, is it possible to melt and cast bronze in a home shop? Absolutely. It melts at temperatures below 2,000° F, so it is easily melted by a propane or natural gas fired crucible furnace. The furnace is a fun project to build, and can be accomplished without expending a fortune.
What is the process of bronze casting?
The ceramic mold is put into an autoclave (Kiln that produces extremely high temperatures), which bakes the ceramic and burns out the wax, leaving a hollow cavity in its place. The ceramic mold is then filled with molten bronze (bronze is an alloy of 85% copper, 5% lead, 5% tin and 5% zinc).
What can bronze be used for?
Bronze is used in the construction of sculptures, musical instruments and medals, and in industrial applications such as bushings and bearings, where its low metal on metal friction is an advantage. Bronze also has nautical applications because of its resistance to corrosion.
What clay is used for sculptures?
Coarse clay is a better choice for hand-building and sculpting as the clay holds its shape better and reduces shrinkage, reducing cracking or warping. For wheel throwing, coarse or grainy clay can cause hand abrasion, so ultra-fine or no-grain clay is the best option. A fine smooth clay also gives a more matte finish.
Are bronze statues valuable?
Well, most bronze statues cost anywhere between a few thousand dollars for smaller statues and well over tens of thousands for larger and more intricate statues.

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. 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.
How can you tell real bronze from fake?
How to Check: Check the metal’s color by scratching the patina, real bronze has a reddish-gold color. But, since there are variations in the portion of the elements of the alloy, colors do vary from yellowish to onyx. But if the color is too blackish, or matted you should be alarmed.

Step 4: Making the 2nd Half of the Mold. Step 5: Adding Sand to the Flask. Step 6: Ramming the Sand. Step 7: Screed the Mold. Step 8: Separate the Mold.
How long does it take to make a bronze statue?
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.
