To check if a sweater is made of pure wool, you can perform a few simple tests. First, look at the care label for fiber content; pure wool will typically be labeled as 100% wool. Next, conduct a burn test: take a small fiber from the sweater, light it, and observe the smell and ash; pure wool smells like burnt hair and leaves a crispy ash. Additionally, you can examine the texture; pure wool should feel soft yet have some natural coarseness, while synthetic blends may feel smoother.
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.

By comparing the measured melting point with the known melting point of the pure metal, the level of purity can be evaluated.
