Always dry your clay completely before firing. If your clay is damp the moisture will try to escape quickly during firing and the piece will break or it could explode while torch firing.
Most metal clay pieces under 15 grams will take a day to dry. You can speed up the drying by using a mug warmer—remember to turn the piece every once in a while. Or you can use a food dehydrator that has been dedicated to non-food use. With these methods it will still take a few hours to dry out.
Do not torch fire metal clay that has been formed over a core, such as a ceramic bead, wood or cork clay.
Always follow the clay manufacturer’s directions for firing. The insert that comes with the clay will explain firing temperatures and timings.
Always fire metal clay, with a torch or with a kiln, in a well-ventilated area and have a fire extinguisher handy.
Keep that clay moist and you’ll be a happy artist! Clay can be stored in a small airtight container and if you are leaving the clay in-between projects, put a small piece of damp sponge in the container. It is also handy to have a small spray bottle handy to re-moisten clay if it starts to dry out.
Keep all the bits and shavings clean. All dried bits of clay can be re-hydrated into a paste, but keep the bits free of sandpaper grit and other work-space debris.
Before you open your package of clay, have your work-space ready. If you are rolling out the clay, have a non-stick work surface ready. (This can be a sheet of glass or plastic.) Lightly coat your hands and tools with olive oil. And lastly—know what you are going to do! Don’t wait for inspiration while your clay is drying out.
