try giving it a little love tap to a hard surface. if it breaks, it's china. to actually answer your question though, there will not be a made in china etched on and it will probably be thin
no its not always going to say "Made in China" on the bong but signs a secondhand bong is China glass.. -crooked percs (dont line up with eachother) -brand name on bong doesnt return results online -bubbles, cracks, shit welds (cosmetic impurities) Sent from my iPhone.
So china glass is just cheap easy break glass? i don't think i can tap and break a bong in store /reason i'm asking lol/
not all china but for the most part yes. save yourself the headache and buy a reputable name brand piece. zob makes quality low budget pieces as well as us tubes if you sacrifice a bit of size for a piece that will NEVER break. trust me, don't buy anything cheap-o unless you want to pay for it in the long run
^^^ This Especially bubbles, as they're easy to spot. Look at the base, is it pitted with bubbles? Check around every joint/weld, bubbles? Check around the mouthpiece. While you can't really measure without calipers and the means to insert them... does the thickness feel consistent? Crooked percs, bases, joints, etc...
Also weight is a factor, "is it lighter than its size would suggest?" Also, if you have a smartphone just get the names and google em in store, if the don't have a name or were " blown locally, chances are the glass is china shit and not worth your time, I have locally blown pieces that kick ass but only buy those FROM THE BLOWER. Otherwise amazon is local as far as you know! Good luck!
