Does anyone have any information or instructional' on how to do a glass on glass joint when blowing a water pipe and/or ash catchers,a.c.,etc. ?? I'm really interested in this whole idea. Any info would be legit.

you need a sand blaster in order to make the glass on glass connection air tight, joints can be purchased in bulk from places like china, although its better to have your own sandblaster because the sandblast will melt, if the flame is too close to it when doing work on the stem or bowl, thats why sandblasting should be the last step. this isnt a how to though...so if you wanna know more, id check out www.thegldg.com ( the best )

worddddd thanks man
