Description
Clay Properties
| Property | Value |
|---|---|
| Bisque Temperature | Cone 06, 998 °C |
| Bisque Porosity | 18–20 % |
| Glaze Temperature | Cone 6, 1223 °C, 30 min hold |
| Total Shrinkage | 12–14 % |
| Final Porosity | 2–4 % |
Note: These properties may vary if fired at different temperatures. Clay properties can also differ slightly between hand-built and wheel-thrown pieces.
Hand-Building (Fired @ Cone 6, 1223 °C, 30 min hold)
| Property | Value |
|---|---|
| Dry Shrinkage | 3–4 % |
| Fired Shrinkage | 8–9 % |
| Final Shrinkage | 12–13 % |
| Absorption | 3–4 % |
Wheel-Throwing (Fired @ Cone 6, 1223 °C, 30 min hold)
| Property | Value |
|---|---|
| Dry Shrinkage | 4–5 % |
| Fired Shrinkage | 8–9 % |
| Final Shrinkage | 13–14 % |
| Absorption | 3–4 % |
Additional Information
Dry Shrinkage: Reduction from manufacturing stage to bone-dry stage.
Firing Shrinkage: Reduction from bone-dry stage to final fired stage (Cone 6).
Absorption: Also called the porosity of the clay body.
Tip: Wheel-thrown pieces may vary in drying and shrinkage depending on water content used.
