The casting metal, is heated until liquefied. The mold is secured to one end of the centrifuge, and a small vessel with a funnel is attached to a hole. The centrifuge creates the best results in casting because the centrifugal force pushes the liquidized metal into the deepest crevices of the mold. A centrifuge is a mechanical device that spins incredibly quickly around one axis. While it is possible to simply pour molten metal into the mold, metal smiths could use a jewelry making technique known as a centrifuge. The extreme heat melts the original wax model, leaving a cavity inside of the investment mold that’s ready for metal.Īfter the loss wax mold has cooled, it is time to cast it in metal. The kiln is run at 1300 degrees Fahrenheit for up to twelve hours, until the mold has completely hardened. Once the investment mold is completely dry, it is cleaned and placed inside a kiln. In the casting process, air bubbles will become tiny metal welts on the final piece, so removing them early on in the process is critical in creating a flawless final product. The filled flask is again put into a vacuum chamber to remove any newly formed air bubbles. The plaster mixture is poured into the flask, covering the wax mold. If a vacuum chamber is not available, the mixture can be left to rest for 10 to 20 minutes for similar results. A fine grain plaster is mixed for the investment mold, and the mixture is placed in a vacuum chamber to remove any air bubbles. Once the wax model is complete, a metal cylinder, referred to as a flask, is attached to the base of the mold, surrounding the wax model. This can result in intricate designs that are near perfect due to the precision of computer design software.

As technology advances, some designers are opting to design their jewelry with CAD software and 3D print their models in casting wax. In this jewelry making techniques the casting process can translate the most minute details into metal, and hard wax is ideal for sculpting intricate models. There are a view techniques that can be used when casting including 3D wax printing, inserting the mold into a vacuum chamber, and utilizing a centrifuge for the molten metal. In this jewelry making technique, a model of the piece is carved from a hard carving wax and is then used to create a plaster mold for the metal to be poured into. Traditionally, cast metal jewelry is made using the lost wax casting method. Below, the experts at MKM Jewelry break down some of the most common jewelry making processes. From lost wax casting and glass fusing to bead weaving and clay jewelry, jewelers use a wide array of techniques to bring their visions to life. However, it is serious and should be done only with the proper safety measures in place.If you know the right jewelry making techniques, anything is possible in jewelry design.
Metalworking is fun and can lead to several opportunities. To get started, consider watching some tutorials, as this will help you visualize what you’re doing before you begin.
#Jewlery casting plaster how to#
This is a basic overview of the steps for how to cast jewelry. Once the metal is fully cooled, you can use a chisel or screwdriver and a hammer to break away the plaster and reveal your metal piece. Be sure that you have the proper safety gear to avoid potentially serious burns. Once you’ve poured your melted metal into your plaster cast, let it cool. This takes the acquisition of mismatched supplies out of the equation, making smelting easy and preparing you for any project. We recommend using one of the Cast Master Elite propane smelting furnaces to ensure you have everything you need to heat your metal safely. Place your plaster mold on a sturdy, flat, and heat-resistant surface and heat your metal. You don’t want the temperature to greatly differ as you pour in your metal. This process will also take excess moisture out of the plaster. Then, place the pan in the oven to allow the wax to melt, leaving behind only the plaster mold.
Place the plaster mold in a pan and use rocks to elevate it off the floor of the pan. Once the plaster hardens, be sure that the wax is visible on the underside of your new plaster mold. Once the wax shape is prepared and hardened, it is placed in plaster. Most jewelry is made from a wax pattern that is used to create an “invested” mold. The first step is to create a wax version of the piece you’re looking to cast. Jewelry casting uses a wax pattern that you can acquire or make yourself. Following the steps for how to cast jewelry should have you on your way to successful artisanship in no time! Wax Patterns Making such dainty pieces requires skill and concentration, but the process will leave you with beautiful products. As you begin to decide on the kind of jewelry you want to make, whether that be necklaces, bracelets, rings, or earrings, you will need to gather certain equipment and learn certain techniques.
