Ceramics and Clay Concepts

This video tutorial covers the basics of ceramics, including its definition and how it relates to clay. It explains hand building techniques such as pinching, slab, and coil methods. The video also discusses welding clay pieces together using the score, slip, and smear method. Additionally, it covers recycling and wedging clay to improve workability and prevent air bubbles. Finally, it provides tips on preventing explosions in the kiln by managing air pockets and moisture levels.

What is the main difference between ceramics and clay?

• Ceramics are only used for sculptures.

• Clay is stronger than ceramics.

• Ceramics are dried and heated clay.

• Ceramics are made from metal.
