A brazier is a container for burning coals or charcoal; it’s used as a heat source for cooking, metalwork, or warming a room. In modern heraldry, it’s also called a “fire-chest”, and is shown as an iron box containing flames [Franklyn 50; Parker 257]; but no heraldic examples of this charge have been yet cited from period armory. As an artifact, the brazier was commonly depicted as a bowl filled with flames; and this is how the brazier is drawn in Society heraldry. (It’s often blazoned “flammant” or “enflamed”, even though it wouldn’t be a brazier without the flames.) The illustration is taken from Jost Amman’s Book of Trades, 1568 . For related charges, see lamp, torch (cresset). See also beacon.
