Unit 1: Pinching

The physical properties of clay, including plasticity, moisture content, and clay “memory,” and how these properties respond to hand pressure.
The structural anatomy of a ceramic vessel (base, body, rim, and foot) and how each part contributes to stability and function.

How intentional control of thickness, compression, and form affects durability, firing success, and craftsmanship.

The historical and cultural significance of pinch-built ceramics, including their use in Indigenous and traditional practices.

Vocabulary specific to pinch construction, including plasticity, pinch method, leather hard, rim, body, and foot.

Use the pinch method to construct a functional ceramic vessel with intentional and consistent wall thickness.

Apply controlled finger pressure and rotational movement to shape the base, walls, and rim while maintaining structural integrity.

Monitor clay moisture and adjust technique to prevent cracking, warping, or collapse.

Evaluate and refine their work during the building process using tactile and visual feedback.

Participate in peer critique using appropriate ceramic terminology and reflective language.

Revise work based on feedback and self-assessment to improve form, stability, and craftsmanship.

• Completed Pinch-Built Vessel: Students will produce a structurally sound, functional pinch-built ceramic form that demonstrates even wall thickness, stable construction, and intentional design.

• Formative Assessment: Ongoing teacher observation using tactile checks (e.g., wall thickness and compression), questioning, and informal critique.

• Summative Assessment: A rubric-based evaluation assessing craftsmanship, consistency of thickness, structural stability, and successful execution of the pinch method.

• Reflection: A written or verbal reflection in which students explain how their manipulation of clay affected the final form and identify challenges and problem-solving strategies used during the process.
