In ceramics, a strip of clay added around the outside surface of a pot before firing for decoration or handling. The cordon(s) may be decorated in some way, for example with fingertip or stick impressions. On wheel-turned pots, cordons may be created by pushing the clay out in a narrow ring from inside, achieving a similar effect. In metalworking, a cordon is formed in much the same way as for a wheel-turned pot, that is, by the repoussé technique.
