Rosin Grades
Gum rosin is classified to different grades
based on the color and the softening point of the rosin. Softening point is the
temperature in which rosin may deform under pressure. In general the softening
point of the rosin reduces as the rosin color gets darker. The table bellow
shows some of the rosin grades and relative properties.
