Can glass be worked on by heating it with a minitorch?

I need to make some custom fabrications of a glass chamber and glass inlets and outlets. I am pretty much trying to make a glass vacuum dessicater chamber. Any help on working with glass is greatly appreciated, this is going to be done at home, I have no special tools or equipment to use, so I am looking for some assitance
It dint work, shatters or cracks the glass
