working with glass at home

Hello, I have a interesting glass question. Would it be possible to take a small (3" long x 2" wide) piece of glass, stick it on a cookie sheet, throw it in the oven at 400 degrees, and be able to flatten it??

Back story: I am trying to come up with a way to recycle used wine bottles. I'm wondering if I could break a bottle, throw the pieces in an oven and be able to bend them. Or if I could set a weight on the glass in the oven.

Does anyone have any ideas for what I could do? Is my oven idea possible??

No, it is not possible. Glass starts to sag at about 1150F (not support its own weight) and slumps flat at higher temps. This is far higher than a home oven can safely achieve even if you mucked about with it. If you follow the links below my signature, you will see some images where I have done exactly what you describe. My kiln/annealer has 4" of frax blanket insulation with about 12 amps at 120 volts heating. It cost about $100 and annealing the glass, if at all thick, takes a ramping controller that with SSR adds about $250.

Of course the answer is no, but it makes me wonder what is stopping you from trying it out? Geez I did stuff like that when I was 10 years old?

I mean didn't you all put stuff in the oven, without asking permission? I tried to cut glass underwater with a scissors too.
