Sparks are tiny flashes of light or radiance. In early Norman heraldry, a field semy of sparks was termed “estencelé”, and was not uncommon [Brault 197]. Estencelé, or estencely, is only found as a semy field; its sparks are not used as individual charges. In mundane armory, estencely is considered negligibly different from a semy of estoiles or mullets. See also ermine spot, semy.
