I have done it several times with a small glass still sold as laboratory equipment. There are several websites out there giving detailed instructions on distillation...the ones I like are out of New Zealand where it is legal. I think that glass, copper, or stainless can work...but not iron or aluminum. One advantage of glass is that you can see and supervise what's happening in there. The biggest issues, in my understanding, are making sure to throw out the first bit that comes off, this is high in methanol and poisonous....having an accurate thermometer helps decide the cutoff point for this, and the other danger is the extreme flammability of the distilled alcohol....it creates a vapor above it like gasoline. Since you're using a flame or heat source to run the still, it's vital to direct this well off to the side, preferably behind some kind of barrier from the flame or heat. With this in mind, I've done it on a propane camp stove many times. It is a good way to convert "bad" wine or other homebrew, and a basic wash to make it can be made out of anything sweet. I have thrown yeast onto dissolved candy, bananas, dried fruit, or whatever....and by the time it comes out of the still and sits on charcoal for a while it all tastes like tequila no matter the source!
