The Liuzhou amber bench
In a narrow lane off the Liujiang river, a one-bench shophouse works on Yufeng Road. It is one of the last glass workshops in Liuzhou that insists on laboratory-grade borosilicate — the kind that can handle a sudden flood of boiling water without a crack. The idea for an amber run came out of that laboratory past — beakers from this bench still turn up in a Liuzhou lab — and after a few visits and rounds of tea, a tinted variant was worked into the regular gaiwan runs.
The amber tint comes from a pinch of iron oxide mixed into the melt: no lead, no cadmium, just a whisper of mineral warmth. Each gaiwan is blown into the workshop’s usual two-part wooden mould, then the lip is fire-polished by hand. The result is a rim so thin it almost disappears against the lower lip. The base is stamped with a small fired crane mark before the glass cools slowly.
This tint was selected after a long afternoon testing heat tolerance, lip comfort, and how the amber performed against different liquors. Because it takes longer at the bench than the clear gaiwans, the amber run makes up only a handful of the twelve pieces in any given month — most of what the bench blows stays clear. This is quiet, functional artistry — a tool that disappears into the tea, except for that gentle amber note reminding you where it came from.
