stretching bottle necks
Hi there,
I know that a similar question was asked not long ago, so forgive me for trying to squeeze a little extra info from you experts. How do you stretch the neck (alone) of a bottle - as I'm sure you've all seen, the neck can be stretched and twisted massively while the rest of the bottle retains its shape. http://cgi.ebay.com/ws/eBayISAPI.dll...ayphotohosting for example. I'd be very grateful for any guidance on this. Many thanks Phil |

stretching bottle necks
These are more complicated than the previous request, which just involved
sticking the bottle in a kiln and letting gravity stretch them. To retain the shape, these would have to be heated to about 1000F in a kiln built for access then a high Btu torch applied to just the neck area, the manipulation done with special gloves or proper tools, held while cool to stiffness, then properly anneal over about 3 - 4 hours. -- Mike Firth Furnace Glassblowing Website http://users.ticnet.com/mikefirth/ "Phil" wrote in message ups.com...

stretching bottle necks
Many thanks for that info, Mike - greatly appreciated. Could I trouble you with a further question about the detail? I'm sure this would be obvious to me if I knew much about glass manipulation but... How would the second part - the torching and stretching - be done? Is it somehow possible to apply a torch within the kiln, or is the bottle removed for the torching? The latter seems unlikely, but if the torching is done inside the kiln.... how is this possible? Please excuse my ignorance, and again - any guidance at all on this would be greatly appreciated.

Very carefully.
The reason for the complication is preserving the shape of the neck (to put the cap back on) and the bottom. It would almost certainly require that the person working be exposed to the heat of the kiln and work with the torch within the kiln. The torch would probably have to be one of the "bush burner" style that puts out 200,000+ Btuh. If they were being made as anything more than a one off, it would probably be worth making a specialized kiln/heating box with a side door (instead of trying to work in a kiln with a top opening door) and then move each one to an annealing kiln after shaping. Just stretching the neck and letting the bottle parts flatten in the heat is much easier, it is preserving the shape of top and bottom that makes it tricky and hot. -- Mike Firth Furnace Glassblowing Website http://users.ticnet.com/mikefirth/ "Phil" wrote in message ups.com...

stretching bottle necks
I saw how it was done many years ago at a local fair. They used an electric
heater that was in a sleeve just large enough to fit around the bottle neck. Just tall enough so the bottle top was exposed out the top. It would heat only that area of the neck. I believe the bottles were suspended in the air by the top of the bottle neck. When the glass got hot enough the bottle would start to drop. At that point is when you start to make your twists. I know this sounds crazy, but they are not annealed after that. Proof in point........the labels are still on the bottles! Randy Hansen SC Glass Tech.

Perhaps the original poster (someone) contacted me with a somewhat similar
description. I just replied. They refered to a #10 can sized sleeve. The labels shown on the bottles on eBay don't count because they are screened paint and will survive the heat, in fact are applied while the bottles are still hot before original annealing. One of the sporting things I have done is cut Coke and other bottles apart, rearrange the pieces, and fuse them to hanging things - the print survives. The bottles can also be sagged flat and have the printing survive. At this link http://users.ticnet.com/mikefirth/wa...tm#FUSEDBOTTLE is an experiment with a Corona beer bottle re arranged into a fuse bowl. I ended the description in the reply with "and pray" because of the lack of annealing. -- Mike Firth Furnace Glassblowing Website http://users.ticnet.com/mikefirth/ "Randy H." wrote in message news:4Hvaf.561$zu6.456@fed1read04...

Hi Mike,
I guess I should have looked closer at the bottle label! I have a bad habit of scratching off the label with my thumb as I slowly saver the evervesence of my beer of choice. That way I do not mix my bottle up with someone else's. I think your right about the Corona, but I'm not sure about the Bud Light bottle. I think this gives me good cause to buy a six pack and do some investigating! I agree 100% on the pray without annealing! Randy Hansen "Mike Firth" wrote in message ...

With paper labels you have to soak them off and glue them on again if near
the heat. I am thinking of making a can to try and do it - I have the parts on hand. The guy goodthngsdontlast selling on eBay says yes that is fine i make them and if you have any questions please let me know Respond to this question in My Messages.

Did some work, bottles survived without annealing, to my surprise.
