Accidentally broke my boyfrients pipe that he lent me while cleaning it! D: [6]

So my boyfrient lent me this bat, a really pretty one he loves, and i was smoking with it just now and after, when i was cleaning it (i like things clean, especially when high, ocd) the top part broke off.

I probably wouldnt have noticed had i not cut my hand while washing. So right where the hole to the bowl is, it snapped. The cuts very clean and mostly straight, so i dont think itd be hard to fix.

Does anyone know how to fix a glass piece? (I can pay for repairs or a new one, just not suure if i can just do it myself) (and im on my cellphone so responses will be slow sorry)
