Made of purple clay from Yixing, China.
Yixing is well-known for the quality of their clays and how the clay can add some minerality to the water, hence improving the flavor of the tea you're making.
Another one of the benefits of drinking tea in this kind of teacup is that the clay will absorb the flavor of the tea. Over time, your seasoned teacup will begin to give flavor back, enriching, and enhancing the flavor of your tea.
