So far this year you have used many tools to work with clay.
To make pinch pots.
To make slabs.
To make coils.
- RIB TOOLS
- SPONGES
- RIBBON TOOLS
- MODELING TOOLS
- WIRE TOOLS
- NEEDLE TOOLS
- POTTER'S KNIFE
- WAREBOARDS
- GUIDE STICKS
- ROLLING PINS
As the clay heats up, the trapped moisture expands and needs somewhere to go. It will push clay out of it's way, blowing up the art. That's why Ms. Land waits at least 2 weeks before she fires something.

MOISTURE
Danny thought he had slip to join his slabs and coils, but he only had yogurt.
Dang it. This isn't Slip.

Levels of Dryness
All CLAY bodies contain some crystalline silica which can scar your lung tissue and cause irreversible loss of breathing capacity. In GLAZES, silica is the component (ingredient) that makes glass.
Uneven drying and Shrinkage will cause cracks.
When you compress clay particles they become best friends that stick together and don't split up while they're drying. Use a rib tool to compress your clay slabs before you trace out your design.

Pyrometric Cones
Temperature is measured in CONES, with low firings ranging in Cone 05 (1875°F) to high firings at Cone 14 (2552°F).
Kiln Cone Chart
Pyrometric cones are small, cone-shaped tools used to measure heatwork, or the combined effect of temperature and time, during the firing of ceramic materials. They are also known as witness cones.
When greenware is bone dry it is bisque fired. Clay particles fuse and converts to bisqueware. Once the piece is glazed and glaze fired it is glazeware.
There are various methods of firing ceramic pottery, but in schools and most ceramic studios a kiln is used.
Horno
Kiln
Este año hemos usado muchas herramientas para trabajar con arcilla.
- Herramientas esenciales:
- Rodillos y palos guía
- Cuchillo de alfarero
- Costillas
- Pasador/h. de agujero
- Esponjas
- Tablero de artículos planos
- Cortadores de alambre
- Herramientas de modelado
Puede reciclarse y reutilizarse.
El término "ceramica verde" hace referencia a objetos de arcilla que han sido moldeados pero que aún no han sido cocidos. La cerámica verde puede incluir arcilla húmeda o seca que ha sido hecha a mano o moldeada en un torno.
Greenware is a term for clay objects that have been shaped but are not yet fired. Greenware can include wet or dry clay that has been hand-built or formed on a wheel.
Greenware
Can be recycled and used again.
Ya no se puede reciclar ni remodelar.
La arcilla que ha sido cocida en bizcocho o esmaltada nunca más se puede ablandar y reutilizar en otro proyecto porque ha sufrido un cambio molecular en el horno.
Clay that has been bisque fired or glaze fired can never again be softened and reused into another project as it has undergone a molecular change in the kiln.
