Product Overview
This is made of natural Whole stone. Carved from dark basalt.
The special conditions and firm structural characteristics formed by the uniform structure, hard texture, compressive strength, etc. of the black store make it have the following unique properties:
1. Good wear resistance, higher than cast iron.
2. The coefficient of thermal expansion is small, and it is not easy to deform. It is similar to steel and is very slightly affected by temperature.
3. It is non-conductive and non-magnetic.
4. The chemical properties of black stone are stable, not easy to weather, and resistant to acid, alkali and corrosive gases. Its chemical properties are proportional to the content of silica, and its service life can reach about 200 years.
Due to the above physical properties, the product made of black stone is easy to clean and is not affected by weather, temperature and humidity, so it lasts for a long time. This teapot is handcrafted in China and is perfect for brewing a quality cup of tea.
