spall - n., a chip, fragment, or flake of stone or ore, esp. one with at least one thin edge. v. tr., to break off chips or fragments, break up into chips or fragments. v. int., to chip or crumble.
One dictionary gives the sample usage "a truck bearing a mound of blue spalls," which is a vivid image. Can also be used in masonry to mean to reduce a rock to an approximately level surface by hammering. In use from at least Middle English, spalle -- origin subject to debate, but some connect it to Middle Low German spalden, to split.
