While not the most durable of charms, a wax amulet is probably the easiest to make, especially with the tools available. A charm made from wax or clay would also be one of the easiest to break if something goes awry. Simply snap it in the hand or under your heel or throw it into a fire.
Wax Charms
Chunks of wax come in a variety of colors, so it’s easy to work color magic into the creation of your charm. The wax chunk may be carved and sanded down just like wood, though it is much softer and easier to mold. Paints designed for candles are available at most crafting stores. These are basically liquid waxes, which may be applied to your wax as you wish. The nozzle makes directing the “paint” in various patterns easier than using a brush. It also allows you to write out spells in whatever magical language you prefer, while giving your charm a bas-relief quality. Or if you would rather inscribe, there are a variety of tools available to carve your words into the surface of the wax.
If you would prefer not to do any carving at all, you can use a mold instead. Melt your wax and pour it into the mold. Depending upon the thickness, leave it to cool for a day or more before removing it from the mold. Use your candle paints to decorate it with whatever charms you feel will express your intent.
Clay Charms
If anything, clay charms are easier to make than wax ones. Shaping you charm would certainly be easier, no carving or sanding required. You can use the same tools to inscribe on clay as you would with wax. The only difference is adding color. For anything beyond the basics, you’ll need access to a kiln.
Hints and Cheats for the thrifty crafter
Dental probes and knives make good wax tools. Your local dentist, dental hygienist, or dental school can supply you with used tools for free. If they don't first sterilize them for you, the procedure is to soak them in laundry bleach for twenty minutes and follow by baking in your oven at the lowest temperature for about half an hour or so.You might also try using the picks that come with a nut cracker.
The wax is so soft it can be carved with almost anything, even if the tool is not hardened steel. Tools can be fashioned from nails, coat hanger wire, and old files.
If you choose not to carve your charm, you can use a round plastic lid from a coffee can or other container as your mold. If you have any trouble getting the wax disk to pop out of your mold, just soak it in some warm water first.
