Are the brooms used in Curling the same as regular shop brooms

l watched a match locally live and they were, but l am sure the Olympic teams have some specially made kinds.

No, they have a fabric designed specifically for melting ice. Although in the old days, corn flaked brooms were used.

No. But way back before the sixties, curlers used a corn broom type of device that was snapped across the path of the stone. Sometimes watching curlers on TV u can see them use those antiques for delivery. But they do not sweep with them. The sweeping now is more of a scrubbing motion & the equipment is specialized

Most brooms have a swivel head & a synthetic material that rubs on the ice with enough friction to generate a little heat to smooth the ice allowing the stone to glide straighter while maintaining its speed longer. Sweeping does not speed up a stone. Other curlers use hair brushes, bristles about 2 cm to an inch long. These work on frosty ice where there is higher humidty.
Brooms with fiberglass handles run under $100. But high tech prevails with the carbon fibre run up to $200 or maybe more.

No. We'd leave debris on the ice.
