Glass Gaiwan, Premium Cooking Grade, Hardened Clear Glass 120ml

Thicker, stronger, and more durable than any alternative on the market, this glass gaiwan has been a cornerstone of our collection since our founding in 2013. In over a decade of sourcing, we have yet to find a glass gaiwan that surpasses its performance or build quality. Cooking grade glass Crafted from high-grade hardened borosilicate glass, this gaiwan is engineered for durability and exceptional thermal shock resistance. While standard glass teaware is often fragile, ours is classified as cooking-grade. It is robust enough to be used directly on an electric stovetop, offering utility that far exceeds traditional glass alternatives. Thick Glass While mass-market options typically feature a flimsy 1mm wall thickness, our gaiwan is constructed with near 3mm glass. This added mass does more than provide a premium, weighted feel in the hand; it offers improved heat retention and durability. As a result, it's suitable for preparing any kind of tea, including oolong and pu erh tea. Visual Clarity & Versatility The crystal-clear glass provides an unfiltered view of the brewing process. From the initial expansion of the dry leaves to the nuanced colors of the tea liquor, every visual detail is preserved, allowing you to monitor the steep with precision. Traditional Design, Modern Build This traditional three-piece set, comprising a cup, lid, and saucer, is designed for professional gongfu style preparation. The saucer features a precision-engineered central indentation, securely anchoring the cup for maximum stability during pours.
