Focus: (Two definitions to write down).

Grog:  Crushed fired clay that is added to wet clay to reduce shrinkage.  It is what gives the clay a sandy or rough feel.

Wedging:  Working the clay in a way that creates a more even clay and eliminates air pockets.  If you do not eliminates air pockets, you will create a pot that could blow up in the kiln and also destroy other student's work.  We use a technique called the "Ram's Head Spiral."
Objectives for today:
1. Continue to recycle clay, as needed.
2. Continue to wedge clay, as needed.
3. Make practice pinch pots.
4. Go over Pinch Pot Unit.
Closure:  When can you not recycle clay?
