PET is Polyethylene Terephthalate, which is a thermoplastic polymer.
It can be re formed by heating. After heating process, it becomes more stiff, rigid, durable and glassy. It becomes even stronger and crystallized when perforated.
This re formed and perforated second life as a bowl is longer and the original bottle.
Object now has an artistic value other than serving as a container for almost any material (eggs, bread, nuts, pencils, soaps, small objects etc.), it can be used as an ideal fruit bowl as the air circulation prevents fruit decay.
Step 1: What you need?
Bottle, cutter or scissors, soldering iron, flame (I use a spirit burner which I made with a jar and cotton cord)
Step 2: Cut the bottle
cut the bottle. you will use the bottom but don't throw away the upper part. there are many ways to upcycle every shred. see the jewelry and accessory made from them at tertium non data
Step 3: Forming
heat the edge over flame and try to give a nice form. but before forming your bowl, experiment several times with leftovers until you have the control over the flame. smaller flame is more controllable. after re-forming the edge, try to heat other parts to give a good form.
Step 4: Piercing
pierce the bowl with the soldering iron. continue to pierce as long as your patience allows. I can do it 4 hours before I give up. this time, I decided to treat only the edge, but I could go all the way.
Step 5: Repeat
repeat the steps until you upcycle all the bottles you have. use them at home, give them to your friends, teach someone to make, even sell them on etsy. http://www.gulguvenc.etsy.com
