What is that white mark at the top corner of the mouth? Bad paint job? Mold? This is a new piece and its been cleaned.
If it's not coming off when you are wiping it, then I would probably think it's a defect from the glass making process. That would be my guess, I see a bunch of tiny looking bubbles in the white spot, which look like glass bubbles.
Glass defect because they hand made more than likely. Human mistakes Sent from my LM-Q610(FGN) using Tapatalk
Yes it's safe to smoke from lol any glass particles (probably aren't any) would fall into the pipe and stick to resin.
