What happens if you put too much rosin on your bow?

Too much rosin will make the bow feel stickier as it moves across the strings. Excess rosin can generate a cloud of rosin dust as you play, and the sound will be harsh and scratchy.

How do I know if my bow has too much rosin?

Acoustically: you shall strike the bow across the strings as a test. If the bow does not slide easily and produces no sound or only a faint, thin sound, then the bow hair does not have enough rosin. But if the bow is very scratchy, then it may have gotten too much rosin.
