The techniques used for jewelry casting
Jewelry casting, also called lost wax casting, only certain jewelry makers are capable of doing, but it’s still good to at least be familiar with the technique so you know what to do if you ever get the opportunity to do it. Jewelry casting is essentially the method by which a wax design is created into molds, typically made of copper or tin-based alloys, and then partially filled with melted silver or gold to create a personalized piece of handmade jewelry. In fact, if you have any knowledge at all about making jewelry yourself, you’ve probably done this once or twice even if you’re an inexperienced jeweler. The techniques used for jewelry casting aren’t too complicated, and anyone can do it successfully with a little practice.
The basic idea behind the casting is quite simple: melted wax (usually soy or vegetable oil) is poured into a mold, and the resulting jewelry design is added to the mold to form a final product. Molds for jewelry can be reused thousands of times before finally being destroyed; they’re made of durable materials such as solid plastic (polyethylene), stainless steel, and cast iron. The equipment required to carry out the process is minimal: a blow torch to melt the wax, and a stainless steel or copper wire cutter to remove the original mold (the molds are often referred to as “dental floss mold”), and then a brass screw or plastic nut can be screwed back into place to hold the new mold in place. As long as the alloy isn’t corrosive, it shouldn’t affect the stability of the final jewelry – all it needs is a quick buffing to get it ready for its first use.
There are two ways to perform this process, traditional casting and direct casting
Direct casting involves melting the wax model in a kiln and pouring it into the mold, while traditional casting uses a mold that contains the wax. To make the latter technique possible, the wax has to come from an organic material and is allowed to cool without any cooling pockets within it – by doing this, it prevents air bubbles from forming, which would otherwise cause the melting process to slow down considerably. Depending on how much detail you want to add to your sculpture, you’ll need either a kiln or a mould exclusively for sculpting. Casting, on the other hand, is a process of dipping the melt into molten metals and cooling it without having to wait for it to come out of the mold – the end result is a piece of jewelry or a decorative sculpture that looks just like it’s made out of precious stones.
Casting can be performed in a variety of different forms, depending on the end product you’re looking for and the material you’re using. It’s commonly used in the creation of acrylic art beads, clay models, and figurines, and also in making temporary tattoos and hair accessories. It’s important to remember though, that the best results are achieved with casted pieces that have a high degree of detail and coloration – a piece of cast wax, for example, will look completely different once it’s dipped and cooled in an autoclave. So if you’re planning on investing in a professional tool, you may wish to consider investing in a professional wax mold, instead.
Casting can be a very enjoyable hobby
If you’re working on an original model, you can actually prepare your own mold. To do this, you’ll need some equipment that can be found at any good toy store, but you’ll also need some special equipment for melting the wax, such as a double boiler, a microwave, a blow dryer, a kiln to heat the clay, a kiln lid, and a non-toxic primer. First of all, make sure you’ve located a good place with plenty of room to pour all the melted wax into. Once this has been done, it’s time to heat the clay till it’s nearly liquid, then pour it into your mold, and then cool it. Wait until the clay is totally cool before you’re ready to remove it from the mold.
Especially if you’re doing it for yourself, because it’s really easy to learn the basics and get going on your own. However, if you’re interested in spending money on a completed product, you should definitely consider investing in a professional tool. There are a few different types of molds, including molded terracotta clay models, which are made by injection molding, and fiberglass, which are made by cold roll forming. One important thing to remember when you’re casting is to use lots of lead-free modeling clay. This will prevent you from ingesting any lead that might be present during the molds themselves.
