| GLOSSARY BB cont. BACK RING
WEIGHT
The amount of momentum (rock delivery force) needed to deliver a rock to a point near the
back 12' ring/line and centerline (backline).
BACKLINE
The furthest rock "out of play" line situated 6' from the hack and which is
perpendicular to the centerline at the back 12' line.
BIO-MECHANICS as related to curling
The study of body motion in the game of curling.
BITER
A stone that is touching the 12' circle and if it is actually 6' from the center of the
rings as measured by the "biter" stick (after the end is over), can be a
potential point. Note: The biter stick can be used to measure IF a 3 guard rule rock is
"biting." This measurement may be needed to determine if the opposing team can
hit it out.
BLANK END
An end of curling play in which no points where scored.
BLANKING AN END deliberately
In a normal game not "skins", the strategy of a team with last rock to
remove all rocks in scoring play to maintain the current delivery rotation (last rock) in
the next end.
BON SPIEL
A curling competition consisting of one or more "events" each with several games
involved.
BRIER
Canadian Mens Curling Championship currently sponsored by NOKIA.
BRUSH
An ice sweeping tool used to clean and smooth the ice in the path of the rock and as a
"crutch " in the delivery sequence (by some). It may be manufactured with a
metal, fiberglass, plastic or wooden handle with a brush head made with horsehair, pig
hair, wool, nylon or various other synthetic cloths. A metal handle is COLD to the touch
and requires the curler to wear gloves - not recommended.
BRUSHING
Unlike sweeping, brushing is referred to as scrubbing the ice surface in a stones
path or intended path to crush large frost crystals into tiny frost crystals that act like water (NOT MAKE WATER) to improve lubrication enabling the
rock to travel further. Contrary to the UBC-Northern physics professor statements
on The Discovery Chanel program.
BRUSHING
THE HANDLE
Brushing the 5" running surface path of the rock ONLY in preference to wasting energy
by "brushing the rock," the 11-1/2" air space path of the rock.
