How Do You Attach Dry Air Dry Clay Together?

To attach dry air dry clay together, you need to create a strong bond by scoring, applying slip, and firmly pressing the pieces together.

Here's a detailed breakdown of the process:

The Scoring and Slipping Method

This is the standard technique for joining any clay pieces, including air dry clay, to ensure a secure and lasting connection.

1. Prepare the Surfaces:

   • Identify the areas on both clay pieces that you want to join.
   • Make sure the areas are clean and free of any dust or debris.

2. Score the Surfaces:

   • Use a sharp tool (needle tool, knife, or even a fork) to create a cross-hatched pattern on both surfaces. This roughens the surface and provides more surface area for the slip to adhere to. Scoring should be deep enough to create texture but not so deep as to weaken the clay.

3. Apply Slip:

   • Slip is essentially clay glue. You can make slip by mixing small pieces of the same air dry clay with water until it reaches a creamy, paint-like consistency (similar to heavy cream).
   • Apply a generous layer of slip to both scored surfaces. Make sure the slip gets into all the grooves created by scoring.

4. Join and Press:

   • Press the two clay pieces firmly together. Wiggle them slightly to ensure the slip creates a strong bond.
   • Remove any excess slip that squeezes out from the joint.

5. Reinforce the Joint:

   • Add a coil of fresh, moist air dry clay along the joint.
   • Smooth the coil into both pieces using your fingers or a tool. This provides extra support and helps blend the connection.

6. Allow to Dry Slowly:

   • Cover the joined area with plastic wrap or a damp cloth to slow the drying process. This prevents cracking and warping.
   • Gradually expose the joined piece to air over several hours.

Why This Method Works

• Scoring: Increases surface area for better adhesion.
• Slip: Acts as a bonding agent, filling in gaps and creating a strong link.
• Pressure: Ensures close contact between the clay pieces and slip.
• Slow Drying: Prevents uneven shrinkage, which can lead to cracks.

Important Considerations:

• Clay Consistency: The drier the clay, the more challenging it is to join. It's best to join clay pieces when they are still slightly moist.
• Slip Consistency: The slip should be creamy, not too watery or too thick. Adjust the water/clay ratio accordingly.
• Drying Time: Air dry clay shrinks as it dries. Allow sufficient time for the pieces to fully dry before painting or sealing.
• Air Pockets: Avoid trapping air pockets in the joined area, as they can cause cracking during drying.
