brocade crown

Brocade is the name of a large gold chrysanthemum with characteristic stars that droop before they burn out. Brocade shells differ from willow shells in that they have a large and symmetrical burst. Brocade stars are often based on charcoal streamer type stars with added metals, for example ferrotitanium

Another name for brocade shells is Crown Chrysanthemum, though that definition can include other streamer effects such as silver.
