I just saw that my bong has a crack in it!

[RainyDayWomen1235]

I just got this the other day and it's a really nice piece... I didn't notice it after taking it out of the freezer yesterday (didn't leave it in there for too long) but today I saw this huge crack. It still works but it leaks... just a bit :(

that to bad, be careful as hell with it, soon as they get a crack in em it just takes the slightest knock to shatter the thing

[RainyDayWomen1235]

yah I'm trying my best to be careful...

I'll I'll just get a plastic one.

hhmm ive heard that if ur bong is real cold and u go to hit it the heat from hitting it is so hot that it cause the bottom to crack....possible?

i really don't see how, i could understand the bowl/stem cracking under those circumstances, but there's a rubber grommet between the bowl/stem and the bong, and rubber doesn't transfer heat too well, not well enough to transfer heat high enough to crack a bong like this, and the smoke isn't that hot, if it were, we wouldn't be able to inhale it without causing some serious harm to our innards.

If it's soft glass then extreme hot and cold can crack it. My buddy bought a bong from our local head shop and they warned him not to put it in the dish washer or put ice in it or it could crack because it's soft glass, it's not treated glass like other bongs. Maybe it's soft glass and putting it in the freezer caused a crack.

It seems pretty hard to me

lol i think you got the wrong idea about 'soft glass' it'll still feel just as hard as other glass, but it's far more fragile.


â??Hard-glassâ?� is an acronym for borosilicate glass like Pyrex or Kimax. â??Soft-glassâ?� is an acronym for soda-lime glass or a higher expansion type glass, (88-92 COE). Lab glass is generally made from â??hard-glassâ?�, (borosilicate), bottles are generally made from â??soft-glassâ?� or soda- lime glass.

Borosilicate glass has not only good temperature resistance but thermal shock resistance as well. Borosilicate temperatures at atmospheric pressure are up to 500°C for the strain point. The softening point is over 800° C. Maximum thermal shock resistance is 160°C. Borosilicate can easily handle most lab temperatures and can easily handle 400-450° C for short term service, typically 200° C for normal service. The thermal shock means that a rapid change from cold to very hot or the reverse will cause fractures. Soft-glass or soda-lime bottles have an upper temperature limit of 400-450° C but have very little thermal shock resistance and can break easily when taken from heat to cold temperatures very quickly. In fact they can fracture if taken from sterilization to room temperature too quickly.

lol.. thanks for the education - it's actually very interesting. But I was just kidding... ;)

use epoxy

[Big Calhoun]

Yeah, I don't think Pyrex glass is used for bong making so putting it in a freezer then immediately exposing it to heat is not the bast idea. Kinda tuff, because if it's a glass bong, it'll still be subject to cracking and expansion as opposed to plastic which can bend and stretch. If the crack is not close to any where you'd put your heat source (lighter), I'd use rubber cement. Reason being that as you heat the glass, it'll still expand some. Most epoxys will dry to a hard consistency with very little flex. So as the glass expands from heat, it'll crack more and eventually break from the pressure. Rubber cement will expand as the glass expands and should give you a little more life out of your bong. BUT...it CANNOT be anywhere near a part of the bong that is exposed to flame or gets heated.

Thanks... but I'll tell ya... the crack starts at the female and runs left across the chamber... this actually does not leak. I have smaller cracks higher up on the chamber that do... but not a lot...

Actually lots of bongs are made out of pyrex but they're more expensive.

They have a windshield fix kit at Wmart. I had a great one crack on me a few years ago. Fixed it right up!!

The kit was only like $7-8.

Would hate to see you loose it!

:stoned:

[infinitibraun123]

nothing a lil duct tape can't fix. might look a lil cheap and ghetto but hell you bought it to get high right?no need to throw it away until if/when it does take a shit on you.

My vote goes to this man. :)

mine as well, if one of my babies cracks on me, i just might try it, tho i would be cautious if the fix will be subjected to any actual flame (or severe heat).
