Chia-Chen Hsieh spent twenty-seven years at the front of a classroom, teaching Taiwanese schoolchildren to draw. Then she went back to being a beginner. She took her place as an apprentice to Jung-lieh Lee, one of the masters Taiwan designates a national living treasure, and started splitting bamboo — at an age when most careers are being wound down rather than restarted. Her own studio opened in 2015. This year a single object made in it put her among the thirty finalists of the LOEWE Craft Prize, chosen from more than five thousand entries across 133 countries.

A sphere nobody built

The work is called Rhythm in Grid. A cube seventy centimetres on every side holds thousands of bamboo strips, each split to something close to the thinness of hair, treated, dyed, finished with urushi lacquer. They are curved and layered and suspended inside the frame — and out of that grid a sphere appears, rippling, as though the cube were water someone had just touched.

The sphere is the part worth pausing on, because nobody made it. There is no ball in there, no armature, no carved form. It is what happens when a few thousand individual tensions are set correctly against one another: a shape that exists only as the sum of other decisions. Trade press called the piece bamboo craft reframed as spatial drawing, which is right, though it undersells the arithmetic. Every strip must be wrong by nothing, or the ripple flattens.

The lacquer sets the tempo

Urushi is the collaborator that cannot be hurried. The lacquer cures on its own schedule, in its own humidity, and no amount of ambition shortens it — a discipline familiar from the kiln that ignores its ceramicist and from the year Hervé Sabin lets a plank sit before calling it finished. Craft at this level is largely a series of negotiations with things that do not care about deadlines. A former schoolteacher, one suspects, comes to that arrangement better prepared than most.

Both ends of the transmission

What makes her story unusual is not the late start — Jane Yang-D'Haene came to clay after three careers, and this shortlist is full of people who arrived by side doors. It is that Hsieh has now occupied both ends of the same relationship. For nearly three decades she was the one transmitting; then she chose, deliberately, to be the one receiving; and now she teaches again, in residencies, in creative hubs, in her own workshop.

Living-treasure systems exist because certain knowledge lives only in hands and dies with them if nobody sits alongside. What such systems cannot legislate is the willingness to sit down — to be, at fifty-something, the least skilled person in the room. Hsieh volunteered. The cube full of trembling bamboo is what that decision looks like when it has had a decade to mature: a grid, given enough patience, learning to ripple.
