What grade does Muyu Stone belong to

Muyu stone belongs to the high-end health stone category, mainly used as a raw material for tea sets, handicrafts, and health equipment. Its value is determined by texture, texture, and processing technology, and high-quality wooden fish and stone products have both collection and practical functions.

Muyu stone is a natural mineral mainly composed of limonite and clay minerals, named after its striking sound resembling that of a wooden fish. Traditional Chinese medicine believes that its nature is warm and sweet, and it belongs to the spleen and stomach meridians. In traditional usage, it is often made into tea or wine utensils, and is believed to regulate human functions through the precipitation of trace elements. High end wooden fish stone products need to meet three conditions: delicate and impurity free stone, crisp and long-lasting knocking sound, and exquisite carving craftsmanship. This type of raw material is mostly produced in Shandong, Henan and other regions, with cloud and water wave patterns being the best textures. Teapots made from this material have good breathability and can soften water quality. Mid range wooden, fish, and stone products are commonly used in daily health equipment such as tea cups, bracelets, etc. The stone is relatively uniform but the texture is ordinary, still retaining basic health benefits. Low end products may have rough stones, obvious impurities, or artificial staining, resulting in lower practical value. It should be noted that some inferior products may be replicated with resin, and their authenticity can be determined by observing natural stone patterns, testing water absorption, and tapping sounds.

It is recommended to regularly wipe and maintain wooden fish and stone tools with a soft cloth to avoid exposure to direct sunlight or sudden cold and heat. Soak in tea for several hours before initial use to activate minerals. Long term use may worsen symptoms for those with weak and cold constitution. It is recommended to balance with warm and warm ingredients such as red dates and goji berries. When choosing, prioritize natural raw stone products with testing reports to avoid excessive pursuit of low-priced products.
