To make polymer clay more malleable, the most fundamental method is conditioning it, primarily through warmth and physical manipulation.
Conditioning is the process of working the clay to soften it and make it pliable enough for sculpting and shaping without cracking or crumbling. This is especially important for older or harder clay.
Manual Conditioning Techniques
The warmth and natural oils from your hands are key tools in softening polymer clay. Here's how to effectively condition clay manually, incorporating the steps mentioned in the reference:
- Prepare the Clay: Start by cutting a piece of clay into a small slab. This makes it easier to handle and begin the conditioning process.
- Begin Kneading: Take the small slab and begin to knead it with your hands. Think of this like kneading dough.
- Utilize Hand Warmth and Oil: As you knead, the clay will start to soften. This is thanks to the natural oil and warmth transferred from your hands to the clay.
- Continue Working the Clay: Once the clay has softened slightly, you can roll the clay into a ball or knead it further.
- Assess and Repeat: Continue rolling and kneading until the clay is smooth, pliable, and holds its shape without cracking when bent. If it's still stiff, repeat the process with the same piece or cut it into even smaller pieces to work more easily.
- Tip: If your hands are cold, you can warm them up slightly before starting.
Why Conditioning Matters
Properly conditioned polymer clay is essential for successful projects. It helps prevent:
- Cracking: Unconditioned clay is prone to cracking during sculpting and especially during baking.
- Brittleness: Malleable clay is less likely to be brittle after baking.
- Difficulty in Blending: Soft, conditioned clay blends colors and seams much more smoothly.
Conditioning not only makes the clay easier to work with but also improves its strength and durability after baking. It's a necessary first step for almost any polymer clay project.
