how to heat & stretch glass bottles  -  colored glass water bottles
Once the glass bottle is emptied, there is no need to turn into garbage.
Instead, they can become art. -
Plates, decorations and decorations-
Through the process of "sliding", heat the glass into the kiln until it becomes soft. (Reference 1)
With the right tools, you can even stretch the glass before it cools down.
Careful heating of the glass will ensure that it remains color and texture while allowing you to reshape the bottle.
Clean your bottle thoroughly with soap and water and then let it dry before putting it into the kiln.
Water will destroy the process.
Scrub any paper or plastic label when it's wet. (Reference 1)
Buy moisture-proof liquid from the craft store, and if the bottle is made of colored glass, spray it on the bottle.
This will keep the color consistent when you melt, reshape and cool the glass.
Set the kiln frame at the bottom of the kiln and cover it with kiln paper.
You can also spray with a kiln.
When the bottle extends down, both methods prevent the glass from sticking to it. (Reference 1)
Hang the bottle around the neck from the top of the kiln.
To do this, the easiest way is to cut the wire on the hanger with a pair of pliers, wrap it around the neck of the bottle, right under the wider section at the top of the neck.
Do this several times until you wrap 5 to 6 hanger lines around the bottleneck.
Bend the wires down so that their free ends extend a few inches to the end of the bottle.
Then you can put everything in the kiln.
The bottle will hang on the wire ring and stretch down under its own weight when heated.
Set the kiln temperature to 500 degrees per hour.
This is the safest speed to heat the glass without the risk of thermal shock. (Reference 1)
When the kiln rises to 1100 degrees, stop heating up for 10 minutes and then continue to heat the bottle at a slower rate of 250 degrees per hour. (Reference 1)
With the heating of the kiln, the glass will begin to stretch down.
Once the kiln reaches 1300 degrees, increase the heat as quickly as possible.
Stop heating when the bottle stretches to your satisfaction or reaches 1425 degrees. (Reference 1)
Break the lid of the kiln very briefly until the kiln cools to 1100 degrees.
This will not make the bottle cloudy.
Once done, just close the kiln and let it cool naturally to room temperature.
This is the last step in the so-called "Annealing" glass.
Once it cools, just open the kiln, pull out the bottle you stretch, and remove the wire rack that supports it with pliers.
