It doesn’t require great skill for you to produce your version of medallions of custom coins that are created with gold or silver materials. Even if you don’t work in a mint, it is still possible for you to make your own coins with the help of metal clay and earthenware clay. With this, you will be able to customize your coins for various purposes, like keepsakes, film props, or jewelry.
To begin with, you may want to make a paper drawing as your guide for your design. You may create this from your computer or simply draw it by hand. Once done with the design, you can then print it. Whether done by hand or through the computer, make sure that you include the outline you’ve made. To ensure the outline is correctly drawn, you may use any similarly sized coin or the basic circle tool found in most image editors.
After you’re done with the design for your custom coins, cut it out while providing enough space beyond the outline. Using earthenware clay, create the mold you’ll be using for the coin. Just pull a chunk of clay as small as the ping pong ball so you can begin molding. First, try flattening an edge against any smooth surface and put your coin design on top of the area. With a nut pick, you can then make the image’s shallow impression in your clay through pressing and then tracing the paper. Make sure you’ve included the outline. By using a needle or toothpick, you may be able to design number and letters.
After doing the molding and tracing, the next thing to do is to wait for the clay to dry up. This would normally take about two hours and the clay will then be dry and very hard. You can then try coating the mold you’ve created with cooking oil. Make sure that you’ll only coat it very thinly. The main purpose of this is to prevent your custom coins from being stuck into the mold.
The next step is hand-conditioning a metal clay piece. You can begin to soften it by working it with your hands. If you feel that the clay is beginning to crumble or dry up, simply add some water. If you’re still working on the clay, just continue adding water so the clay will not dry out.
You can then create a disc from your metal clay. Start rolling your clay until it becomes a ball and try pressing it against the smooth surface you’ve been working on. Let one side flatten and do the other by simply flipping it.
Push one surface of your disc against the earthenware mold and press over the disc’s back side very gently. You can easily do this using your thumb. This way, the impression could be made on all parts.
Afterwards, pull the coin out from your mold and cut out the excess clay from its edges with the help of your scissors. If you want, you may create ridges around the coin’s edge by rolling it against the bristle sides of a fine-toothed comb. If you are to hang your custom coins, you can create a hole by using a needle or toothpick. Allow the coin to fully dry up. This may take the same amount of time you’d wait out earthenware clay to dry up. You can then fire the metal clay and brush it based on manufacturer instructions. As a precautionary measure, you should strictly follow every instruction of the manufacturer and do not overlook safety warnings, particularly when you’re about to use fire for the custom coins.
