So, I'm a little concerned. I bought [and loved] the B0 BALL VAPE that I got on sale directly from CANNABIS HARDWARE. However, after a few uses, I noticed that each time there was a residue left in the bong that was not "normal". Instead of the usual dark brown/black coating on the inside, it was a bluish color. Anyone else have this experience or know what it is? I'm thinking of doing some testing myself on it to find out, but I have to research methods of identifying combusted residue, which will take time. Assistance would be much appreciated
