Which hand building method is NOT used when working with clay?

The blowing method is not used in traditional clay hand building techniques. Hand building involves shaping clay using manual methods that utilize the hands or simple tools to create objects. The coil method, pinch pots, and slab building are all foundational hand building techniques.

In the coil method, long rolls or "coils" of clay are stacked and joined to form walls or shapes, allowing for the creation of various forms such as pots or sculptures. The pinch pot technique involves using the fingers to pinch and shape a lump of clay into a hollow vessel, emphasizing tactile manipulation. Slab building involves rolling out sheets of clay and joining them together to form structures, which can be shaped into boxes, tiles, or other geometric forms.

In contrast, blowing is not a recognized method in hand building with clay. Instead, it might refer to techniques used in glassblowing or ballooning, where air is used to create shapes, which is fundamentally different from the direct manipulation of clay that characterizes hand building methods. Thus, it stands out as the only option not aligned with clay hand building practices.
