Rosin Question

July 11, 2020, 4:26 PM · I have some Clarity brand rosin that seems like it has gotten old and hard. I’m not sure that I’m getting enough rosin on the bow. Is there a way to revitalize Clarity rosin? Thanks

Edited: July 11, 2020, 8:23 PM · The Clarity brand of rosin is a synthetic substance that is not rosin, and I do not believe that it is soluble in alcohol.
The inventor of the substance posted quite often at one point here, so perhaps he will chime in.

I discuss the process more in detail and recommend some rosins that might be better than the Clarity for a Hypo-Allergenic option.
