I like to do shellac from flakes and have a couple bags (blonde and garnet) since 2014 or thereabout. Needed some garnet so set to make a 3# cut for about 3 oz. After 1 day the mix instead of having a clot of shellac in the bottom was like a suspension , not foamy but looking like that. The alcohol was from an old can or bottom of old can. Had this happen once before with the blonde but the next time it worked fine. Anyone know what is going on?
