• Knead the clay well before you start working with it. This will help smooth it out and remove any air pockets that could cause it to break. If the air pockets do not dissipate, puncture them with a pointed tool and roll them back through the rollers. This will remove any trapped air.
  • Be sure to follow the manufacturer's cooking instructions. Proper baking is crucial to the strength and durability of polymer clay. Make sure not to under or over expose it to the oven. A polymer clay can be baked for up to 45 minutes without burning, increasing the flexibility of the piece, as long as the temperature is within the range suggested by the retailer.
  • Make sure you are working with a good quality clay. When choosing a polymer clay, opt for well-known and trusted brands that offer good elasticity and strength.
