I have found so many vases that would suffice for cool tube glass in asda. All shapes and sizes. My question is how (if you can at all) would you go about cutting the base of these off? They are cheap too, and a cut one would resemble a bake a round. Cheers.
You could use a small propane or butane torch to cut out the base, but take all proper cautions to catch any falling molten glass (i.e. do it in your garage or outside, not on your new dining room table).
Taking a torch to certain glass will cause it to shatter and not melt. Trust me I've tried it. NOt to mention the heat the glass will have to endure when a HID light is inside of it. Not all glass is the same. You need tempered glass.

Get a glass cutter and try that. Score it's surface, I'm guessing this should be done as straight as possable. I've seen plumbers do this to glass tubing used in drains...2' in size. Then with safty glasses and gloves, long pants, sleeve shirt....tap tap tap. Just an idea. Make sure you wear glasses and all that stuff.

Diamonds are forever! FOREVER! :D
My brother broke apart his earrings since he has insurance or someshit on em and cut some glass before.
Basic, tempered glass for high time , will shatter when a cutter breaks the inter part.
Plain glass will not take the direct heat.
Use a tube bread tube, and do not screw with it, adapt it.
Use a Dremel with a fiber cut off wheel. Go a little deeper than a score would then try snapping, if this dont work use the Dremel and grind all the way through. If the glass is lime, pyrex or quartz glass heat can be used, You dont have to get it molten just red hot, use MAPP gas, then use shears or tin snipps, if its at the right temp it cuts like paper, but tends to stick to the cutting edge. If its that cheap ordinary, sheet or window glass just use a file and sand paper. Concrete works well as a sanding device. Hell I've heated up and ground down piles of glass, just for the fun of it. I hate the type that explodes as its cooling down, cool down that type in an oven slowly.
