ghosted
adj.— «The marshals got to the ground floor, where the fire had been hottest and raged the longest. Every step of the stairwell and each railing and inch of banister was alligatored. Parts of the wall were “ghosted,” fire parlance for places where fire burns so strong that it erases its own soot, leaving raw, bleached patches of brick.» —“Working Backward and Seeking Reasons in the Ashes” by Cara Buckley New York Times Mar. 10, 2007.
