How to Knead Kato Polyclay?

Kneading Kato Polyclay, often referred to as conditioning, is crucial for making it pliable, smooth, and ready for your creative projects. The process typically involves an initial softening phase followed by a refining phase to achieve the perfect consistency.

Why Condition Kato Polyclay?

Kato Polyclay, especially when fresh or cool, can be quite firm. Conditioning warms the clay, distributes its plasticizers evenly, and makes it flexible enough to prevent cracking during sculpting and to ensure it cures properly. Properly conditioned clay is easier to work with, holds detail better, and yields a stronger final product.

Initial Softening: Breaking Down Stiff Clay

For particularly stiff or fresh Kato Polyclay, starting with a powerful method can significantly reduce the effort required for full conditioning.

1. Mallet and Bag Method:

   • Place the desired amount of Kato Polyclay into a sturdy, resealable plastic bag.
   • Using a mallet or a rubber hammer, repeatedly hit the clay firmly. Aim for even strikes across the clay piece.
   • After several good bashes, you'll notice the clay starts to soften considerably, making it much easier to handle for the next steps. This method is highly effective for quickly breaking down hard clay.

2. Using a Neverknead:

   • The Neverknead is a specialized tool designed to quickly condition polymer clay.
   • Follow the manufacturer's instructions for loading and operating the device. It applies significant pressure to warm and soften the clay efficiently, preparing it for further conditioning.

Refining the Conditioning: Achieving Perfect Pliability

Once the clay has been initially softened, you can complete the conditioning process to achieve a smooth, workable consistency.

1. Pasta Machine:

   • A dedicated pasta machine is one of the most efficient tools for conditioning polymer clay.
   • Start with the widest setting on your pasta machine.
   • Flatten the softened clay by hand slightly and feed it through the machine.
   • Fold the clay and feed it through again. Repeat this process, gradually decreasing the thickness setting, until the clay is smooth, pliable, and free of cracks or crumbs. You'll know it's ready when it can be folded and passed through without tearing.

2. Acrylic Roller or Brayer:

   • If you don't have a pasta machine, an acrylic roller or brayer can also be used.
   • On a clean, non-porous surface, flatten the softened clay with your roller, pressing firmly and evenly.
   • Fold the clay, rotate it, and continue rolling. This manual process takes more time and effort than using a pasta machine but is effective.
   • Ensure you maintain even pressure to avoid thinning out one part of the clay more than another.

Tips for Efficient Conditioning

• Warmth Helps: Work in a warm environment, or gently warm the clay slightly (e.g., hold it in your hands, place it near a warm-not hot-surface, or use a mug warmer on a very low setting) before conditioning.
• Small Portions: If working with a large block of clay, cut it into smaller, more manageable portions to condition them one at a time.
• Patience is Key: Conditioning can take a few minutes, especially for very firm clay. Don't rush the process; thorough conditioning leads to better results.
• Cleanliness: Always ensure your hands, work surface, and tools are clean to prevent lint or debris from embedding into your clay.

By following these steps, you can effectively knead and condition your Kato Polyclay, preparing it for beautiful and durable creations.
