- The main decision to make concerns the array of classifications of metal clay you will use: lump, syringe, slip or paper. What distinguishes these formulas is primarily how long they need to be fired (double-check with the manufacturer) and the ratio of metal to organic material.

Currently, most consumer clays are low temperature with a low percentage of metal particles. This means that using a kiln is not a necessity unless the clay requires a temperature starts at 1,600 degrees F (871 degrees C) to turn into metal. If you have cost-effectiveness concerns that are preventing you from getting access to a kiln, which can run from $100 to $800, consider the varied other mediums a kiln requires.
A hot pot is a cheaper option that follows the same principles of the kiln, but you will also need a heating fuel. If your clay requires a torch, torches need a ceramic tile to hold your clay as you fire it up. - To prepare the clay, you can start by laying down graph paper. This will help you line up the clay and cut evenly. On top of that, place a clear plastic or otherwise clean square. Cards from a playing deck can be invaluable when rolling clay if you book-end the clay with an equal number of cards. You will need a roller to spread and lay down the clay. The best tool for cutting is something like a utility knife or dental tool, if available. Optional but helpful is a smoother for edges of the clay, sold at ceramic stores, but a small paintbrush will do the trick.
- Since clay is sticky, a small amount of olive oil on your hands and roller will reduce this. Metal mesh can be used to dry clay before going into the kiln or being heated. Clay may get a bit dry during your project, so a few drops of water will keep you moving along. You'll undoubtedly end up with extra or cut-off clay. Put it in a jar with some water to keep the clay together for your next project.
