Detail 01
Rosin cake
Bow hair alone will not grip the string. Rosin is what creates the friction that makes the note speak.

JadeViolin-Viola-Cello Rosin
Independent shopping perspective
The Korena take
Rosin for bowed string instruments — violin, viola and cello. A basic cake to give bow hair grip on the string.
Strong match
Who this is for
- Restocking when an old cake is worn down or cracked
- Students needing a first rosin with a new bow
- Households with more than one bowed instrument
Consider the trade-offs
When to look elsewhere
- Double bass players — bass needs a softer, tackier rosin
- Players chasing a specific dark or light rosin character
- Anyone with a rosin allergy handling it bare-handed
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Violin/viola/cello
One formula across all three. Cello sometimes prefers a slightly softer cake, but this works on all of them.
Detail 03
Solid block form
You drag the bow hair across it. It wears down over months, and a cracked cake still works if the surface is intact.
Final check
Know before you order
- 01Rosin only — no bow, no cloth, no case included
- 02New rosin needs scoring with sandpaper before it grips a fresh bow
- 03Wipe rosin dust off the instrument top after playing or it hardens into the varnish
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How often do I apply it?
A few strokes every couple of playing sessions. If the bow slips and the tone thins out, it needs more. Caked white dust means too much.
02Can I use this on double bass?
Not ideally. Bass rosin is much softer and stickier to move the thicker strings. This will grip poorly on a bass.
03My new cake will not stick to the bow.
The surface is too smooth. Lightly scuff it with fine sandpaper or a key edge to expose fresh rosin, then draw the bow across it.
04Does it matter if it cracks?
No. A cracked or chipped cake works fine as long as there is a usable surface to draw the bow across. Only the exposed face matters.
