Sourced from Handan’s glass quarter
Sandry Law spends most of his procurement cycle in Yunnan, but when tea.glass needed a larger fairness pitcher, he went north — to Handan, Hebei, a city with a two-century tradition of borosilicate glass work. The workshop he found is run by a third-generation blower who supplies lab equipment to Beijing universities and, increasingly, the tea trade.
The Handan 300ml was born from a problem: most 200ml gōng dào bēi force the pour-er to angle too sharply, spilling the last few drops. The solution was not just more volume, but a spout geometry that empties the belly completely at a natural 45‑degree tilt. Sandry and the blower spent a week testing prototypes — adjusting the neck height, the loop handle’s attachment points, and the base thickness so the pitcher wouldn’t tip when half-empty.
What emerged is a piece that feels almost invisible in use. The glass is thin enough to transmit heat without scorching fingers, thick enough to survive a knuckle tap without ringing. Every Handan pitcher goes through a 12‑hour annealing cycle, which is why there are no stress fractures near the handle joint.
This is not a factory item. It is made in runs of 40, signed by the blower on the box, and each one is inspected by Sandry herself before it leaves the Kunming warehouse. She considers it the quiet workhorse of any multi‑cup gongfu table.
