Does anyone know how to make the wine bottle edge? After cutting the bottle how do you make the edge smooth and melted looking, not sanded? I have a kiln, and already slump bottles. Any clues, anyone?

You have everything you need, if your kiln is big enough! Just stand it cut end up in the kiln and heat slowly to about 1400~1700 F and keep a close eye on it. With the cut end towards the top it should get hotter quicker than the bottom. When it looks rounded to your liking, flash cool it to a temperature. When the glass is stable, then cool to room temperature like any other project.
You can also do this with any torch that has a blue flame. You will still need to bring the whole bottle up to temp. before tying to round over the top edge, or it will shatter. Just remember, glass does not like to change temperature up or down quickly, and you will be OK.
PS. Figure on a few failures, and take notes!
