Rosin, explained
From baseball's rosin bag to a violinist's bow: why this tree resin is so good at adding grip.
Rosin is a natural resin that comes from pine trees and other conifers. When the sap is collected and the liquid part (turpentine) is distilled off, what remains is a solid, amber-coloured material. That is rosin, also called colophony.
Why it grips
Rosin is slightly tacky. Spread thin on a surface, it raises friction, so things that would normally slide start to hold. That is exactly the property athletes and musicians want.
Where you have already seen it
- Baseball. Pitchers have a rosin bag on the back of the mound and pat it to dry and tack up their fingers before a pitch.
- String instruments. Violinists and cellists rub rosin on their bow hair. Without it, the bow slides over the strings and barely makes a sound.
- Ballet. Dancers step into a rosin box so their shoes do not slip on the stage floor.
Rosin in ONGrip
Natural rosin is the main grip ingredient in ONGrip. Instead of a powder or a block, it is dissolved in a quick-drying formula with glycerin, so it goes on as a fine spray and dries into a thin, invisible layer on your hands. You get the tack of rosin without the dust.
