The bar is a thin, horizontal stripe across the centre of the shield, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). It is also possible to place decorative edges along bars, typically these are smaller than those found on the major ordinaries like the fess and pale, but have the same design and share the same meanings. An line drawn indented, i.e. in a saw-tooth pattern might be taken for dancettee, but in this case the individual “teeth” are much smaller. An early author, Guilllim seeks to associate this decoration with fire A Display of Heraldry, J. Guillim, Blome, London, 1679, P39, and one can see the resemblance to flames.
