Pirastro Goldflex Rosin


French and North American pure resin has a light yellow color while German pure resin is rather brown. Pure natural resin is transparent, can be easily pulverized and dissolves in alcohol and essential oils.
In a successive stage, the pure resin is heated up again while oil and other materials are added. This liquid will then be poured into a mold to form the cake of rosin that
musicians are using for their bow hair. Each manufacturer has his very own specific procedure to make rosin which he protects as a strict secret. As a consequence, all rosins today differ in quality and impact the bowing technique and the sound color of an instrument immensely. For the musician it is thus important to carefully choose a rosin which helps him to have the most ideal grip of the bow while playing the strings.


Which Rosin should I use?

High quality rosin allows for perfect bowing without scratchy sounds, especially if only a thin layer of rosin is applied. The general rule is:

  • violinists and violists use a harder, dryer rosin
  • cellists use a medium strong rosin
  • bassists a softer rosin 


Another important aspect for choosing the right rosin is the core material of the string that are being used:

  • steel strings are easier played if you use a hard, dry rosin
  • for synthetic, gut and gut wound strings use a softer rosin

Moreover, experienced players prefer softer rosin when playing in a studio and harder rosin in a concert hall. Hard rosin works best in tropical climates while soft rosin is good for cold climates.

We develop our own specific rosin and design it according the technical requirements of our different string lines. That is also the reason why we name our rosin after the brand names of our violin and viola string lines.




Each cake of rosin is glued onto a soft cloth which then is attached to a hard plastic grip. This prevents the fingers of the musician to get exposed to rosin dust and also makes it easier to apply the rosin.
