Polymer clay is a type of modeling clay based on the synthetic polymer polyvinyl chloride (PVC). Unlike traditional, earthen clays that require a high-temperature kiln to cure, polymer clay hardens at much lower temperatures.

Here are key components that give polymer clay its unique properties:

  • PVC provides the plasticity, allowing the clay to be easily shaped and molded.
  • Plasticizers make the clay soft and workable; without them, the PVC would be too hard to manipulate.
  • Pigments are added to the base material to create a wide range of colors.
  • Fillers, such as kaolin clay or mica, can be introduced to give the clay body and reduce cost.

Once baked, the plasticizers in the polymer clay react, solidifying the material into a hardened, durable form. It’s this transformation that makes polymer clay a versatile medium for crafters and artists.

Conditioning Polymer Clay

Before you can mold polymer clay into your desired shapes, it’s crucial to condition it to improve its workability and prevent any potential brittleness after baking. Think of conditioning like kneading dough; it makes the clay pliable and easier to work with. Here’s how you can do it effectively:

  • Start by warming the clay in your hands to help soften it. As the material heats up from the warmth of your hands, it becomes more malleable.
  • Flatten the clay into sheets and then fold and roll it repeatedly. If you’re conditioning by hand, use a smooth, flat surface and a rolling pin or brayer. This process aligns the polymer particles, which ensures even baking and strength.
  • If the clay is particularly stiff, you can use a pasta machine set to a medium setting for a consistent thickness. Pass the clay through several times, folding it between each pass. Adjust the thickness gradually to prevent any tearing.
  • If you find the clay too hard, certain brands offer clay softeners or plasticizers that can be mixed in to ease the conditioning process.

Remember, the clay should never feel crumbly or stick to your fingers excessively. Once it’s smooth, flexible, and holds its shape without cracking, it’s ready for crafting.

By Hand

Conditioning is crucial to make polymer clay malleable and ready for work. Begin by warming it in your hands, then press and fold the clay repeatedly. If it’s particularly stiff, try flattening it with the palm of your hand on a clean surface. As it becomes more pliable, roll it into a ball and then into a snake shape, fold it in half, and repeat. This process ensures an even texture and eliminates air bubbles, which can cause issues during baking. Remember, the warmth from your hands combined with systematic kneading are the keys to successful conditioning.

Using a Pasta Machine

For a uniformly conditioned polymer clay, a pasta machine is an invaluable tool. Set the machine to its widest setting to begin, and pass the clay through several times. Each pass warms the clay and improves its pliability.

After each pass, fold the clay and feed it fold-side first into the rollers to prevent air pockets. As the clay softens, you may gradually reduce the thickness setting until you achieve a consistent, smooth sheet. Remember to clean the rollers with a baby wipe or paper towel in between colors to avoid transferring hues.

Additionally, it’s worth noting to never use a pasta machine for clay that’s also used for food to prevent cross-contamination.

Baking Polymer Clay

To ensure your polymer clay creation hardens correctly, follow these essential baking tips:

  • Always check the manufacturer’s instructions for the recommended temperature and bake time as it varies by brand.
  • Preheat your oven to maintain a consistent temperature.
  • Use an oven thermometer to ensure accuracy, as some ovens can be off by 10–25 degrees.
  • Lay your piece on parchment paper or a ceramic tile to avoid direct contact with the oven rack which can cause uneven heating.
  • For thicker pieces, consider tenting with aluminum foil to protect against scorching.
  • Baking times typically range from 15–30 minutes per 1/4 inch (6mm) of thickness.
  • After baking, allow your creation to cool slowly to room temperature to prevent cracking from thermal shock.

Temperature Guidelines

To achieve the best results when baking your creations, always refer to the manufacturer’s instructions on the packaging, as different brands and types may have specific requirements. Generally, the optimal temperature range lies between 215-300°F (102-149°C). The clay should be placed in a preheated oven to ensure even heating.

Use an oven thermometer to check the accuracy of your oven’s temperature settings, as fluctuations can lead to under or over-baked pieces. For consistent baking, place pieces on a ceramic tile or oven-proof glass surface.

Items thinner than 1/4 inch typically bake well within 15-30 minutes, while thicker pieces may require up to an hour or more. Avoid opening the oven door frequently, as sudden temperature changes can affect the baking process.

Remember, polymer clay does not harden until cooled, so allow your items to cool slowly once the baking cycle is complete. Rushing the cooling process, for instance by placing hot items directly onto a cold surface, can lead to cracking or warping.

Timing for Different Thicknesses

To achieve the best results when baking polymer clay, you must adjust the time based on the thickness of your project. Thin pieces, such as petals or earrings, might only need 10-15 minutes, while thicker items, like large beads or figurines, usually require at least 30 minutes.

For every quarter inch of thickness, it’s a good rule of thumb to bake for 30 minutes. Always check the manufacturer’s recommendations as they can vary by brand and product line. Remember that multiple thin layers or parts can be added and baked in stages to ensure thorough curing without burning.

It’s also crucial to use an oven thermometer to ensure your oven is at the correct temperature, since fluctuations can affect how the clay cures.

Storing Polymer Clay

To maintain the quality of polymer clay, proper storage is essential. Keep the clay in a cool, dark place to prevent premature hardening. It’s advised to place it in tightly sealed plastic bags or containers to protect it from dust and dirt. Some clays can leach out their plasticizer, which might stick to certain materials, so it’s good practice to wrap the clay in wax paper before storing.

Avoid contact with polystyrene or PVC, as these materials can react with the clay. Organize different colors separately to prevent them from transferring colors onto each other. Remember, while it’s durable, polymer clay can get somewhat brittle if compressed for too long, so avoid piling heavy objects on top of it.

Health and Safety Precautions

Working with polymer clay is generally considered safe if basic precautions are followed. Ensure adequate ventilation in your workspace, especially when baking the clay, to avoid inhaling any fumes. Wearing a mask can provide additional protection.

Always follow the manufacturer’s recommended baking temperatures to minimize the release of potentially harmful compounds. If the clay is overheated, it can release irritating gases. It’s advisable to use an oven thermometer to monitor the temperature accurately.
