First off you cant make a hole in glass with a torch lighter, it doesnt have enought heat or pressure so the glass will crack before it melts. second, a mig weldor works on an electrical arc so it will have no effect on the glass. A torch will do the job if you have an oxygen tank and argon but i dont suggest using it unless you have expirience with them as they can be dangerous. it has a lot of heat and pressure so it will cut a hole through it in no time. good luck.

Well I want to make my own glass bong and I have all the materials but I was wondering, would a small butane torch lighter be hot enough to be able to make a whole through decently thick glass. When I say decently thick, think glass vase. I was planning on heating it with that and using a pen the right size to push through. If all else fails, I'll go to my dads car shop and use a real torch or mig welder. Thanks for the help! Rating: 5
