i havn't tried to scrape it, i couldn't really even tell that there was a coating until I burned it
bebacha Reviewed by bebacha on . Glass Pipe QUESTION I found some a glass object that would be perfect to smoke out of, but i think that there is some kind of coating covering the glass. When I put a lighter under it, it gives off a black smoke, and leaves black ash that wipes off easily. I have tried boiling the glass, shaking in alcohol and salt, and washing, but it still gives off black smoke. Is there any way to completely remove this coating?? Rating: 5
