What is the function of calipers in a workshop?

Calipers are precision instruments used primarily for measuring the dimensions of objects. In a workshop, they provide accurate measurements of various materials, including the thickness, diameter, or length of items being worked on. They are particularly useful for tasks that require fine measurements, such as checking the gauge of materials, ensuring part compatibility, or maintaining consistency in thickness for art projects or construction.

The other options involve different tools or processes that do not align with the primary function of calipers. For example, cutting fine details into clay typically requires tools like knives or sculpting tools. Mixing clay with water is a task done by hands or specific mixers, while applying patterns onto clay might use tools such as stamps or rollers designed for texture and detail work. Each of these activities serves a distinct purpose that calipers do not directly facilitate.
