How long did it take you to rosin your bow till you got sound out of your violin?

I rosined mine for an hour and still didn't get any sound :(

If possible, it's best to "prime" the raw hair, before applying your regular rosin.  It's simple enough to do, but required crushed/powdered rosin.  You simply take a piece of cloth or leather (I use leather), dip it in the powdered rosin, and then rub it across the hair.  You want to rub lengthwise and perpendicular until the entire length of the hair is primed.  Then, prime the other side.

If you don't have crushed rosin, you can buy a cake, place it in a zip-lock, and crush it with a hammer.

However, if you don't prime, you should still be able to get the rosin to adhere in under an hour.  Perhaps you have old or very cheap rosin, that has dried out?  Perhaps the bow has synthetic hair?

I also recommend roughing the surface of the rosin with some sandpaper before using, though that's not strictly necessary.

I have just had mine re-haired and lo! Two swipes with the rosin and we were away! Is it definitely a rosin problem though?

Use a quarter's edge to score the face of the rosin. A new, smooth cake will take longer.

Joe beat me to it. Score or scratch the surface of the rosin.

    When I've had new bows, it hasn't taken long for me to get a sound out of them, but there are usually little bald spots which take me by surprise with sudden silences in the middle of tunes. I always rough up the rosin a bit before I start. Once, the luthier had given me some high-class dark rosin for free, but it must have been old, because it just turned to gritty powder when I applied it, and in the end I had to junk it.

I realized that when I put too much pressure when applying rosin, I can get a scratchy sound but with a light pressure, i'll get a smoother sound.
