Melting glass?

Is it possible to melt a hole in glass with a normal blow torch.

    No
    Not only does the torch not get hot enough (by “normal” I’m assuming a propane torch) but the flame isn’t concentrated enough. Glass conducts heat incredibly well, so you have to have an exceptionally hot, concentrated flame or else the heat that would normally melt the hole will be conducted away from the spot so it would never get hot enough. Because glass is also very susceptible to expansion due to changes in its temperature, if you heat too quickly in an attempt to get the one spot hot enough to melt a hole, it will most likely crack or shatter before the hole is ever made.

    Glass is not a very forgiving thing to work with. Stick with a specialized glass drill bit for that hole.

    It depends on the type of blowtorch and glass. Some glass melts higher than a camping stove can heat it. If you have a welding torch or butane torch it should be no problem.

    yea, after a while, why not it has to be hot though

    You really need to be careful. Some glass is tempered, and if you try to heat it, it can fracture or explode. Some glass, like soda bottles is actually coated with a chemical that prevents it from scratching or breaking. The easiest glass to work with is laboratory glass, which is made to be worked with. Some laboratory supply houses will offer things like glass tubing which are easy to work.

    If you want some good advice, call a glass-blower in your area and he or she might be able to help. They might even give you a demonstration on working with glass.
