Abstract
A curling broom includes an elongate shaft having opposed first and second ends, the first end being graspable by a sweeper and being attached to a broom head attachment plate located at the second end. A curling broom head is attached to the broom head receptacle for sweeping an ice surface. The broom head includes a base section, a reflective constituent selected to reflect infrared radiation which can be a layer secured to a bottom surface of the base section, or the top of the woven fabric or both or a reflective powder incorporated into a foam pad attached to the base section, (or the foam pad being metalized), or an outer surface of an outer fabric layer being metalized and secured to the base section. Infrared radiation generated by sweeping the ice is reflected by the reflective layer back towards the ice surface for further heating the ice surface.
