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??
can you scrape it off?
i havn't tried to scrape it, i couldn't really even tell that there was a coating until I burned it
im pretty sure that all glass does that, take a glass pipe that was meant for smoking and do the same thing to it and it does the same thing.
what was this glass object origianlly used for?
The glass was from an old chandellier part. I don't think that burning a normal glass pipe produces black smoke
i think your right it might be LEADED GLASS. they use to put lead in glass in the old days.how old was the chandellier?Quote:

it's in the glass. they put lead in glass till around 1920-1930 i think dont quote me on that.Quote:

yeah, they put lead in glass during the industrial revolution.
either that, or it's pyrex coating. but i doubt it.
Okay, guys, a couple things:
-First, leaded glass is still common nowadays; they don't put lead in window glass anymore, but any high quality cut crystal is made from leaded glass.
-Second, Pyrex is not a coating. They cool the glass down very slowly after forming it so it cures very hard and strong, sort of like tempering steel. There's no coating-- you're thinking of safety glass.
-Finally, the black residue is from the lighter. Butane is, chemically speaking, C4H6. When burned (2C4H6 + 11O2 --> 8CO2 + 6H2O), the IDEAL results are just gases-- carbon dioxide and water vapor. However, the reaction isn't perfect because of impurities in the butane and other environmental factors, so you get other byproducts--namely, carbon. That black stuff is just carbon residue left on your pipe by the flame.
Hope that clears things up.
how the fuck do you knw that shit holy fuck
the man most likely majors/minors in chemistry.
o.
sweet.
Actually, last year's Chem AP course taught me the combustion stuff; the lead stuff I learned while helping my mom pick out a nice leaded glass vase; and the pyrex stuff I learned when I asked my mom, "hey mom, what's with all the glass bowls you have in the kitchen that say Pyrex on the bottom?"
But on a side note, I do plan to major in chemical engineering next year.
