Tempering a length of piano wire over a small flame always leaves a dark blue scale if the heat isn't drawn off in time. Rolled tight around a three-millimeter mandrel, it keeps just enough spring memory to push an escape lever back without fatiguing the pivot. I scratched the turn count across the corner of an old invoice. The room stays warm tonight—twenty-two degrees—so the wire cools slowly, settling into an even, predictable temper.
