How do you morph a glass bottle? Answered

 How do you morph bottles like in the pictures? I tried with my torch,  and absolutely failed, it cracked, and didn't soften. Am I an idiot, or does this take special equipment?

 It would be nearly impossible to do this with a torch. Glass is really brittle, and heat expansion often shatters it.

This is done with a kiln. The kiln slowly ramps up the temperature until a 'slumping' temperature it reached. The bottle gets soft and collapses under its own weight.

Go to Craigslist.com, and buy a kiln :D

I think you need a Kiln, or some other hot oven. Raving' should pop up and give you the definative on this.

Maybe star with the torch pretty far back, using wide sweeping motions, and gradually (very gradually!) bring it  in closer until the flame is just about to touch the glass. Then leave it there for five minutes. This may use a lot of propane, or whatever is powering your torch. I'm no expert at this, I just thought id put in an idea.

a young lady I know does this using a kiln. First she carefully removes the labels, then she "melts" the bottles in a kiln, once they have cooled she reapplies the labels. Its labor AND energy intensive but she makes decent money at craft/art shows

.  You are probably concentrating the heat in one spot, causing stress cracks and eventually catastrophic failure. Heat the glass slowly. If the glass is very thick, heat it even more slowly.
