Silicon Bronze Ingot for Bronze sculpture. (Ingot weights are plus or minus 2.5% as all ingots are different sizes) This is now the preferred bronze for sculpture due to it's easy flowing properties. Clean ingots will not require flux but when old pouring cups, and runners/risers are melted which may contain investment flux may be necessary.

Bronze casting methods have been used for thousands of years across different continents to create objects in bronze. Bronze is a relatively easy metal to cast, given its chemical properties, and is a relatively inexpensive material. This guide will walk you through precisely what bronze casting is, a brief history, and how to get started.

Bronze casting is the process of pouring molten bronze into a hollow mold to create a positive bronze sculpture or object. Methods of bronze casting, like lost wax, ceramic shell, and sand casting are used to produce bronze sculptures, instruments, medals, tools, plaques, and more.

Bronze is the most popular metal to use for casting sculptures because of its versatility and ease of casting. When casting bronze, the material expands just before it sets, helping bring even the most minor details to life. It also constricts as it cools, making removing the finished cast from the mold easier. Because bronze is copper-based, it has a lower melting point than most metals. Beyond sculptures, bronze is also an excellent material for casting musical instruments, weapons, medals, industrial parts, and more. It also resists corrosion, making it a long-lasting option for sculptures and more.

The first known bronze sculpture dates back to 2500 BCE. Other early bronze objects, including cast weapons and tools, were found throughout modern-day India, Africa, China, Greece, and more. Bronze sculptures were one way great civilizations of their time tracked history, practiced ritual, and honored nobility.

Bronze casting processes have been around for thousands of years and are widely used for creating sculptures, instruments, parts, weapons, tools, and more. It is a versatile process that utilizes different types of molds and materials depending on the project you would like to cast. The following is an overview of the different bronze casting processes and methods.

Lost wax casting is used to create a one-of-a-kind, detailed metal object by building a mold around a sacrificial wax model. After the mold investment is set, the wax is melted out and forms a cavity where the bronze flows in. When the bronze cools and solidifies, the artist can remove it from the original mold.

Sand casting uses resin-bonded sand to construct a mold that the bronze will be cast into. When the mold is cured and the pattern is removed, you can flow molten bronze into the hollow area. Once it cools, the result is a single cast metal object.

Sculpting large-scale bronze pieces often begins with the artist studying the sculpture on a small scale by making smaller mock models of the larger project. When the time comes to make the final mold for the large-scale sculpture, the artist must keep in mind structural support and logistics. The final model may be sculpted in clay, plaster, or wax. For very large pieces such as life-size sculptures, they may be cast in pieces then welded together before the finishing process.

Chasing is removing seams and repairing imperfections on the wax model before casting. Because bronze is a detail-oriented casting metal, every tiny mark will show. It is much easier to eliminate these marks through chasing in wax than in the cooled bronze object. Chasing tools used include heated soldering irons, heat guns, and texturing tools such as dental or miscellaneous hand tools.

The Crucible offers a wide variety of classes teaching bronze casting and metalworking techniques. Whether you want to learn the fundamentals of casting or something more advanced, The Crucible has you covered. We offer bronze casting classes in both our Foundry and Jewelry Departments. Our Foundry offers students an opportunity to create their own sand molds and ceramic shell molds. We offer a fully-equipped wax room where you can also shape and detail your patterns for lost wax casting. In our Jewelry department, you can make your own unique small pendants, rings, and more to be cast in bronze. Our jewelry classes allow you to learn the full metal casting process from creating a wax pattern to pouring molten metal, then finishing your piece.

Ceramic shell is a mold material used in the lost wax casting method. Learn basic wax-working techniques and explore basic metal finishing in this fascinating course. You will create a wax sculpture and build ceramic shell molds, transforming your original wax piece into bronze.

This class is for people with metal casting experience who have completed waxes to cast. We can also accommodate 3-D printed PLA (best unpigmented). Students will prepare their patterns, gate them, build the ceramic shell mold, cast in bronze, destroy the mold, and remove the gates.

Bell Casting introduces participants to bell design and the lost wax foundry technique. In this class, you can design, cast, and finish a bronze bell approximately six inches in diameter. This entry-level class provides a foundation for further exploration in this versatile foundry approach.

Overall, bronze is an excellent sculpting metal because it is easy to work with and allows details to show through. In addition, it is a hard metal that is not brittle or prone to breakage when worked. After casting, bronze begins to contract in the mold, making it easier to separate from the mold once it has thoroughly cooled. Bronze is also incredibly versatile for the finishing and patina stage. Patinas can be applied to give a bronze object the appearance of silver or gold.

It is best to start bronze casting with a professional instructor in an established casting studio. Bronze casting can involve more advanced equipment that can be costly to set up. The safest and least expensive way to start is in a public class. Once you have experience and a strong understanding of the process and tools involved, you can explore setting up a studio at home.

The melting point of bronze varies depending on the exact alloy composition. Most bronze alloys contain about 90% copper. The remaining 10% may be a mix of tin, aluminum, nickel, or zinc. The average melting point of bronze is between 1790-1900 degrees Fahrenheit. Molten bronze stops flowing when it hits colder temperatures, which can occur when molten bronze is poured into a room-temperature mold. Therefore, it is essential to preheat ceramic shells and casting molds to approximately 1100 degrees Fahrenheit in a kiln before pouring.

The casting process has been used for thousands of years for making sculpture, jewelry, tools and more. Here at PMC Supplies, we specialize in offering tools for both melting down precious and non-precious metals and pouring them into a mold. We carry graphite, steel, and cast iron molds to mention a few. These molds are offered in a variety of shapes and sizes to accommodate your specific needs. We also carry a full line of melting furnaces, crucibles, and torches for the initial melting process; as well as handling tools and safety gear for handling your metals during the casting process. Whether you are out mining for your own gold, have scrap jewelry you want to melt down, or simply practice metalworking as a hobby, we have the tools you need to cast your metals from start to finish!

Metal casting can be a lucrative hobby when dealing with precious metals. With the proper tools and equipment you can begin melting down your own gold, silver, and copper materials into bars or other forms for resale. We also carry all the necessary accessories and chemicals in order to refine your precious metals to an even more purified state, allowing you to get top dollar for your material.

An inexpensive casting method where a sand and clay mixture is used as the vessel in which to pour your molten metal. The sand/clay mixture is often contained in a metal flask or mold in order to be able to compact the material to a dense state for optimal pouring results. Due to its malleable texture, sand casting can be used to replicate intricate objects by pressing the object into the sand to leave a negative impression of the design that is then filled with your molten metal. You can also carve patterns or designs directly into the compacted sand. The mold is filled with the molten material which will then cool and harden. Once the metal has solidified, the mold can be hammered in order to crack the sand and expose the metal object.

This casting method can be used with aluminum, bronze, cast iron, steel, and magnesium alloys and is best for casting metals with intricate detail or complex designs. This casting method will require molten metal, a metal die, wax, ceramic slurry, furnace, and a machine for grinding, cutting, or blasting.

We offer a variety of Melting Furnaces and choosing the right one will depend on how much material you are looking to process at one time, the area where you plan on doing most of your melting, your budget, and of course your experience level.

Graphite is an ideal material for metal casting as it can withstand extremely high temperatures. Metals will release with ease and you will not require the use of a releasing agent or lubricating spray. We also offer customized engraved and custom shaped graphite ingot molds upon request. Graphite molds will start to deteriorate over time and after repeated use. Most customers find they can use a graphite mold between 30 to 60 pours before they need to be replaced. *The exact number of uses will vary.

We highly recommend doing research and educating yourself before beginning a casting or refining project. There are many crucial steps, processes and safety measures you will need to be familiar with before successfully carrying out your project. If you are brand new to casting, or are somewhat experienced but are looking to expand your knowledge base, we offer a number of books that specialize in casting and refining. 041b061a72
