Transparent Glass Gongbei Tea Server | High-End Tea Ware | Handmade "Stubborn Stone" Gaiwan 100ml

Crafted in Boshan, Zibo, Shandong, the birthplace of Chinese glassmaking, this piece hails from a region with a thousand-year history of glass artistry. It inherits the ancient Boshan glass-making techniques and holds national Geographical Indication certification. Historically known as "medicinal jade," glass was once exclusively used by royalty in ancient China. Boshan glass is recognized as an international intangible cultural heritage. This vessel offers multiple values, serving for daily tea brewing, desk display, aesthetic appreciation, and as a collectible. Craftsmanship Introduction: Each piece is entirely handmade, employing traditional Ming and Qing dynasty wax-lost casting and hand-blowing techniques. Over forty meticulous steps are completed by hand, culminating in its tempering within a 1400°c high-temperature kiln. During the firing process, the body naturally develops a fine, dense bubble texture reminiscent of crystalline formations. The unique pattern distribution of each piece is a gift of nature, making every item one-of-a-kind. Material Description: Locally sourced natural mineral powders from Boshan are melted at high temperatures to create a dense, high-silica body. It possesses a substantial, reassuring weight and emits a clear, resonant sound when gently tapped. The lead-free, safe formula has passed authoritative testing for food-contact materials, ensuring peace of mind for daily tea brewing. The colors are integrated into the glass body itself, not applied to the surface, ensuring they remain vibrant and unfading over time, becoming more refined with each use. Important Purchase Information: * This work is handcrafted by artisans, not mass-produced by machines. The distribution of bubbles and textural details will vary slightly in each piece. * Due to the nature of handmade glass firing, minor imperfections such as tiny pinholes, natural dark spots, subtle lines, or slight polishing marks may occur. These are inherent characteristics of traditional handmade craftsmanship and are not considered flaws, nor do they affect normal use. They are simply the unique marks of the object's life. Gentle Reminder: Handmade glass products are not highly heat-resistant materials. Please avoid drastic temperature changes during use and do not pour boiling water directly onto the vessel.
