Wondering if it's possible to do custom work to a bong

Ok so have a roughly 18 inch to 20 inch bong delta 9 is brand and use it for concentrates is it possible to heat the glass bend it at an angle and put carb in .......and would not be doing this myself would have a glass blower do it if I can find one haha......

seems like if you could find some one who knows how then it should work just fine just have to find that person

yes.. but.. to do it right they'd have to have a large kiln to re aneal the tube for you. Otherwise it's just waiting to shatter. For the amount of work and time you might as well have him make you one the way you want it in a new one rather then mod the old one.
