What Will Happen if I Mix Two Rosins Together?

If you mix two rosins together, eventually the new rosin will start to work its way through the hair, however this can take a little while, and you’ll always have some residue sticking around from your old rosin.

Rosin makers spend countless hours creating rosin recipes which are the perfect blend, intended to produce a desired effect. To fully appreciate this effect, players should always start a new rosin on new horsehair or horsehair that has been cleaned by a Luthier.

This is especially important for advanced or professional players who are usually looking to refine their sound with rosin and achieve a certain sound or playing quality. On average, these players have their bow rehaired every 6-12 months, which is usually when they decide to try out a new rosin.

Beginner to intermediate players shouldn’t be too concerned about mixing rosin as they may not notice the different between their old rosin and a new one, especially if they are both dark or both light.
