Testing a china clay sample
Testing a china clay sample. China clay (or kaolin) is a material often extracted from quarries and requires quality testing for industrial uses. In this case, she is likely performing a test to measure the physical properties of the clay, such as its compressive strength, particle size, or density. The machine she is operating might be assessing how the clay performs under pressure or other stresses, which is critical for applications in ceramics, paper production, and other industries. This kind of testing ensures that the extracted clay meets the necessary standards for its intended use.
