To successfully attach wet clay to bone dry clay, you must score both surfaces and use slip. The process allows for a secure bond, preventing the wet clay from simply falling off the dry clay.
Steps for Attaching Wet Clay to Bone Dry Clay
Here's a breakdown of how to securely join these two clay states, incorporating information from the reference video:
- Scoring:
- Begin by using a scoring tool to make shallow, crisscrossed lines on the surface of both the wet clay piece and the bone dry clay where they will connect. These lines provide texture for the slip to adhere to. The video highlights scoring the handle of the wet clay and the attachment spot on the dry clay.
- Slip Application:
- Apply a generous amount of slip (a creamy mixture of clay and water) to both scored surfaces. The slip acts as a glue, creating a strong bond.
- Joining:
- Press the wet clay firmly onto the bone dry clay, ensuring the scored areas are well-matched.
- Blending:
- Once the pieces are joined, blend the wet clay into the dry clay to create a seamless connection using a tool or your fingers. This will also help prevent future cracking.
Why These Steps Are Necessary
- Bone Dry Clay's Nature: Bone dry clay is extremely absorbent due to the lack of moisture and will quickly dry out the wet clay if not properly prepared. Scoring allows for a better mechanical grip, and slip provides the necessary moisture for the two pieces to join.
- Preventing Cracking: The slow drying process caused by this method is essential for preventing cracking. Rapid drying can lead to the wet clay contracting too quickly, which pulls away from the dry clay.
- Achieving a Strong Bond: Properly scoring and applying slip creates an interface between the wet and dry clay, creating a more robust structure.
By following these steps, you will effectively join wet clay to bone dry clay, allowing for a secure and lasting bond.
