You can perform a microscopic purity test by using transmitted light to see if the fibers form simple shapes. For example, cashmere's fine fiber will appear as small blocks next to each other. Pure cashmere is always labeled as 100% cashmere and it is soft and slippery, but if it is part silk, it will appear shiny.

How a thermometer can be used to check the purity of a metal?
A thermometer can be used to check the purity of a metal by measuring its melting or freezing point. Impurities in a metal can alter its melting point, so a pure metal should have a specific and consistent melting point. By comparing the measured melting point with the known melting point of the pure metal, the level of purity can be evaluated.
