LARICA Metal Rosin is manufactured in several hardness grades and with various metal additions.

The hardness decreases from I to IV. The softer grades of hardness essentially make the hard and sharp sounds of the instrument milder and make the tone nobler. The harder rosins can make softer sounding instruments clearer and more distinct.
The rosin is perfect for newly built or Baroque instruments as well as all instruments in the Chrotta Family.
