How to Cast a Sculpture in Bronze
I Want to Cast My Sculpture in Bronze. Where Do I Start?
You make the art. We help you figure out everything that comes next.
Have a sculpture you'd like to cast in bronze?
Whether you're starting with a finished clay, plaster, an existing sculpture, a small maquette, or a digital file, ART Research Enterprises can help you determine the best path from your original artwork to a finished bronze.
And you don't need to understand the foundry process before contacting us. That's our job.
Our team works directly with artists throughout the bronze casting process, from mold making and enlargement through casting, metal finishing, patina, mounting, delivery, and installation.

What Do I Need to Cast a Sculpture in Bronze?
Not as much as you might think.
If you're ready to explore casting your sculpture, a few photographs and basic dimensions are usually enough to start the conversation.
Your sculpture might currently exist as:
- a finished clay original
- a plaster or other physical pattern
- a small-scale maquette
- an existing sculpture you'd like to reproduce
- a 3D scan or digital file
- a concept that still needs development or enlargement
We'll review what you have and help determine the appropriate next steps.
Not sure whether your sculpture is ready for the foundry? Send us some photos.
How Does a Sculpture Become Bronze?
Bronze casting is a multi-stage process. At ART Research, we use the traditional lost-wax casting process along with modern digital technologies when they make sense for the artwork and the project.
The exact process varies depending on the sculpture, but a traditional bronze typically moves through these stages:
1. The Original Sculpture
Everything begins with the artist's original artwork.
This may be a finished clay, plaster, another physical material, or a digitally produced pattern.
2. Production Mold
A rubber production mold is made from the original sculpture to accurately capture the artist's surface, texture, and detail.
The mold becomes the tool used to create the wax patterns needed for bronze casting.
3. Wax Pattern
Wax is produced from the mold, creating a hollow reproduction of the original sculpture.
Our team carefully cleans, fits, and finishes the wax so the artist's original surface is maintained.
4. Gate & Vent
A system of wax gates and vents is attached to the wax pattern.
These create the pathways that allow molten bronze to enter the mold and gases to escape during casting.
5. Ceramic Shell
The prepared wax is repeatedly dipped into ceramic slurry and coated with refractory material, gradually building a strong ceramic shell around the wax.
The wax is then removed, leaving a hollow mold ready to receive molten bronze.

6. Bronze Casting
Bronze is melted and poured into the ceramic shell.
Once cooled, the shell is removed to reveal the raw bronze casting.
This is the moment the sculpture becomes bronze.

7. Metal Chasing & Assembly
The individual bronze castings are cleaned, welded together, and carefully chased.
Welds and casting seams are worked back into the surrounding surface so the completed bronze maintains the character and detail of the artist's original sculpture.
8. Patina
The bronze surface is prepared and patinated using heat and carefully applied chemicals to develop the final coloration.
Patina can range from traditional browns and greens to more complex finishes depending on the artist's vision.
The completed surface is then sealed and protected.
9. Finished Bronze
The result is a permanent bronze sculpture ready for presentation, mounting, delivery, or installation.
Original Sculpture → Mold → Wax → Ceramic Shell → Bronze → Metal Chasing → Patina → Finished Sculpture
Can You Enlarge My Sculpture Before Casting It?
Yes.
Many artists come to us with a smaller maquette that needs to be enlarged before it can be cast.
Depending on the artwork and the artist's preference, enlargement can incorporate traditional sculptural methods, 3D scanning, digital modeling, CNC processes, or digitally produced patterns.
The goal isn't simply to make the sculpture bigger. It's to preserve the character and intent of the original artwork as it changes scale.
Can You Cast a Sculpture From a Digital File?
Yes.
Digital technology has become another tool available to artists and foundries. ART Research works with digital files, 3D scanning, CAD, and digitally produced patterns when appropriate for the project.
Some sculptures may move through a primarily traditional process. Others may combine digital and traditional techniques.
We don't believe the technology should dictate the artwork. We determine the process that makes the most sense for the sculpture.
How Much Does It Cost to Cast a Sculpture in Bronze?
There isn't a single price per pound or per inch that accurately determines the cost of casting a sculpture.
Bronze casting costs depend on several factors, including:
Overall size and surface area
Complexity of the sculpture
Mold requirements
Number and complexity of cast sections
Metal finishing and assembly
Patina and surface finish
Mounting requirements
Edition size or number of castings
Delivery and installation requirements
For an initial estimate, we generally don't need elaborate drawings or specifications.
To get started, send us:
Photographs of the sculpture
Overall dimensions
Material of the original
Number of bronze castings desired
Any known mounting or installation requirements
Your anticipated schedule
If some of those details haven't been determined yet, that's okay.
We'll help you work through them.

How Long Does It Take to Cast a Sculpture in Bronze?
Bronze sculpture is made through a series of skilled, hands-on processes, and production time varies considerably based on size, complexity, foundry schedule, edition quantity, and the amount of finishing required.
Once we've reviewed your sculpture and understand the scope of the project, we'll provide a production schedule along with your estimate.
If you're working toward an exhibition, dedication, installation, or other fixed deadline, tell us about it early in the conversation.
Do I Have to Be Near the Foundry?
No.
ART Research is located in Lancaster, Pennsylvania, conveniently positioned between Philadelphia, Baltimore/Washington, DC, and New York City, but we work with artists and clients throughout the United States and world wide.
Projects can be coordinated remotely through photographs, digital files, drawings, video meetings, and approval milestones. Artists are also welcome to visit the studio and participate directly in the process.
That's part of the philosophy behind:
Where Our Studio Becomes Yours.
What Happens to My Original Sculpture?
This is something first-time foundry clients often worry about.
Before beginning mold production, we'll discuss the material and condition of your original sculpture, how it will be handled, and what the mold-making process will involve.
Different original materials require different considerations, so we evaluate each sculpture individually before production begins.
Can I Be Involved During the Casting Process?
Absolutely.
Some artists prefer to leave much of the technical production to our team, while others enjoy being closely involved in approvals, metal finishing, patina, and other stages.
Both approaches work.
Our role is to provide the technical expertise and craftsmanship necessary to translate your sculpture into bronze while respecting the artistic decisions that make the work yours.
Ready to Talk About Your Sculpture?
You don't need a formal RFQ, engineering drawings, or a complete production plan to start a conversation with us.
If you have a sculpture you're considering casting in bronze, send us a few photographs and its approximate dimensions.
We'll take a look at what you have and help you determine the next step.
Let's make it in bronze.
