Ley-Glass Annealing Banks
AE-408Era: ember-ageTech tier: 2
Veilspire’s cliffside annealing galleries pace ley through sand and iron so storm glass cools without shattering—and Syndicate assay reads the curve like a signature.
Banks along the rack\n\nVeilspire’s cliff racks do not only grow storm glass—they teach it patience. After a pane leaves the brine and the first ley kiss has set its grain, guild teams wheel it into annealing banks: long stone galleries where heat is not fire alone but a paced ley current run through iron rails and sand beds.\n\nEach bank is a row of sealed bays. A master temper listens through a horn of smoked quartz while apprentices adjust clockwork dampers that throttle how much ambient surge may enter from the city’s roofline lattice. The goal is cruelly simple: cool the glass slowly enough that its inner weather does not crack its skin, yet fast enough that Syndicate assay windows stay profitable.\n\n## Why Syndicate clerks care\n\nIron Syndicate assay marks treat annealing curves like handwriting. A bank that runs “hot-nosed” or “salt-shy” leaves signatures in the glass that orrery makers reject, and mirror laboratories read as gossip about a season’s ley budget. Temper masters therefore keep duplicate dampers—one set honest, one set polite.\n\n## Hazards\n\nWhen ley-tides spike, a bank can sing. The song is beautiful and expensive: panes may take on unintended harmonics that later ring false in binding sigils or answer storm glass out of season. The city fines careless banks in glass tithes and, in worse seasons, in silence.
