Cobalt and Sun-Tail Hummingbird — Vermicular Reactive Stained-Glass

A 35×25cm die-cut suncatcher designed from Vincent Wisbey's own vermicular reactive cobalt glass — the dramatic milky-white vein patterns running through the deep blue aren't printed graphics. They're authentic worm-line striations formed during firing when copper carbonate and silver nitrate naturally react against each other in the kiln cooling cycle (Latin: vermiculus, "little worm"). Every sheet is one-of-one chemistry. Final 53 from Vincent's Edwardian rope-shed workshop on the Great Ouse quay in King's Lynn before he closes end of July 2026 to move in with his brother Gerald after his MND diagnosis.
