Off topic but could impurites in the vinegar cause initially white fluffy spice to turn a semi-sticky yellow/orange color? This is using  your tek 2. I mentioned this in another thread a while back for the record. Also this hasn't caused any change in purity or potency when smoked. Actually I kind of think I'm pulling a little jungle spice when this happens. But after evapping the spice is a beautiful white fluff but after a couple days it turns color and gets a little sticky. Puzzling! Of course it could be naptha I reckon.
