Pinch Pot technique is described as:

• A. Working with clay without a pottery wheel
• B. Using the potter's wheel to throw clay objects
• C. Creating a pot by starting with a ball, inserting the thumb, and pressing the sides
• D. Assembling pieces of found objects into sculpture

Answer: (C)

Pinch pot is a hand-building method in ceramics where you form a pot by starting with a ball of clay, inserting your thumb into the center to create a hollow, and then gently pinching the walls to shape and thin them. This step-by-step pinching and rotating the clay produces the vessel without using a pottery wheel. It’s distinct from wheel throwing, which relies on a spinning wheel to shape clay, and from assembling found objects into sculpture, which isn’t about forming a hollow vessel. So the description that matches is starting with a ball, inserting the thumb, and pressing the sides.
