1. Stages of clay Plastic Leather hard Bone dry Bisque Glaze Greenware
Glazeware

2. Plastic/Working Clay –
Clay that is in a workable form.
It can be formed and retain its shape.

3. Leather Hard – The stage where the clay is soft enough
to carve or cut yet hard enough to stand
on its own or support itself.
Two pieces can be joined together.(Slip and Score)

4. This is the most fragile stage of clay.
Bone Dry –
This is the most fragile stage of clay.
All or most of the water has evaporated .
It looks and feels dry. – no cold to touch

5. Unfired pottery; still being cleaned
Greenware – Unfired pottery; still being cleaned or sanded. Clay is fragile at this stage, but not as fragile as bone dry.
Greenware –
Unfired pottery; still being cleaned
or sanded. Clay is fragile at this stage,
but not as fragile as bone dry.

6. Bisqueware –
Unglazed clay that
has gone through the
First Firing!!
By bisque firing,
the clay
becomes stronger.

7. Pottery that has been coated with a glaze and refired
Glazeware –
Pottery that has been coated with a glaze and refired

8. Clay Construction – Slip and Score
How do you join to pieces of clay?
Slip/Liquid Clay – Score-
Clay + water = Slip Cross Hatching
Used as a glue Marks made where
to join clay Clay will touch

9. Clay Maintenance – Wedging
remove air bubbles, achieve uniform consistency,
and to line up the particles of clay

10. Additive – When you add material to a sculpture to build up the form Subtractive- When you subtract material from the sculpture to build up the form

11. Main construction methods
Main construction methods Pinch- made with the pinching of fingers and thumb . Coil- gently rolling clay back and forth to create coils and using those coils to build up a form. This process is great for large asymmetrical forms . Slab- Using a slab roller or guide sticks to form slabs and cut and join with other stiffened slabs to create the form. Best for tall straight cylinders

12. Pinch Pots

13. Coil Pots

14. Slab Pots

15. Kiln- Furnace in which Clay is fired The First firing of a clay object is called the Bisque firing. The second Firing of a clay object is called the Glaze firing.

16. Glaze- Liquid suspension of material that melts in the kiln and produces a glasslike surface provides Beauty, Strength, and Waterproofs the piece Brushed on at the Bisque stage

17. Glaze Before kiln----- -------After Kiln
