Our bow resin (rosin) is manufactured in different compositions and qualities to suit the artist and to fulfil the various conditions of the climate. We offer EUPHON (spruce resin) which we are producing for Violin and Viola, and also artist‘s- and special rosins made of larch resin. This rosin will be manufactured for all instruments in 3 degrees of hardness. Only tropical rosin is produced in one hardness for hotter climates. Bow resin is made for the proper connection between hairs of the bow and string surface, and this firm grip is increased by special mixtures and technical treatments; this is the difference between special- and artist‘s rosins.
