Lead glass is not in any way harmful and is really crystal not glass.. Some folk will believe anything.
Use a diamond tip drill.
Gently exert pressure on the glass and you should have no problems.
psychocat Reviewed by psychocat on . Can you drill a hole in glass ? what is needed ? what type of drill bit ? I want to make my own bong , and I have a really nice piece of glassware i want to use , and then add my own bowl etc. Can this be done ? I practice drilled a Corona Beer bottle and it shattered just as i drilled through . :( Rating: 5
