I'm wondering about the quality of the product i have. It melts at a high temp and is difficult to burn. It also leaves very little residue. It also seems to produce more hits from less product. Are these signs of a quality purchase or have i just convinced myself of it. Which would put my belief it's better quality and better effect only in my head? One more question and that do quality rocks look like gypsum crystals to you too?
