Glass bottle cutting that wasn’t…


My sister said she would like to have some glass chimes like the old type from China we had when we were kids. I guess that are still available because I found them online. But NOOOO, I have to try and make some glass chimes.

I had, and I mean had, a bunch of wine bottles saved up that I’ve been wanting to cut. I went to Hobby Lobby and bought a very inexpensive bottle cutter called the “G2 Generation Green Bottle Cutter”. Thankfully I had a 40% off coupon on my very cool Hobby Lobby phone app otherwise I’m not sure it would have been worth $25.  I went home and tried it and it was a disaster. So…I went online and looked for others that looked more user friendly but didn’t cost a fortune. I found one called the “Kinkajou Bottle Cutter”. It was expensive but it looked like it worked pretty well. I put it in my cart, started the checkout procedure but didn’t buy it. The next day I get an email that say’s, ” you forgot something in your cart. Price too high? how does 15% off sound?”. So dummy me buys it. I say dummy  because I should have sent them an email and ask if you could cut rings with it. They shipped it the next day so I got it really fast and my instant gratification was satisfied. But, I sure didn’t have much luck cutting rings with it or the G2 for that matter.

I finally watched a bunch of videos on YouTube from the G2 company and also a bunch from various people about how to cut bottles. I especially concentrated on the part for separating them. I found out something very important about myself. One, I was determined to get them (the cutters) to work and two, I am very impatient. As Violet on Willy Wonka says, “I want it NOW!”. I either would get the water too hot or the cold water too cold. I tried the boiling water/ice water thing but 9 times out of 10, actually almost 10 out of 10, they would crack and not in a good way. So I thought how can I get the temperature of the hot water right without needing to measure the temperature all the time. A-Ha! My sous vide cooker can maintain a constant temperature! It worked! Of course by this time I figured it out I was down to my last bottles and they were the blue ones. The special ones. I love cobalt blue glass. So here are the results.

I don't know how many bottles I tried to cut but it must have been at least 25!

Fortunately I work with glass and pottery. My plan is to make some molds out of clay, bisque fire them and Bob’s your uncle! I’ll have glass molds I can use this mound of broken glass in.  I will say the Kinkajou cutter can cut things the G2 can’t. A friend gave me a set of cobalt blue glasses because she knew I worked in glass. The color is the most beautiful blue! I was able to cut quite a few rings out of those glasses using the Kinkajou cutter. I went ahead yesterday and did a test fire to slump a little of the glass. I have a small glass kiln that someone gave me that works perfectly for that kind of thing. Here are the results of the trial batch. I wasn’t able to flash cool them so they devitrified which is to say they formed crystals on the top of the glass but still they turned out pretty good. I like the odd shaped one especially.

Here are the slumped rings from the bottles I cut. Now I just need to make a mold to slump the 90% of glass that broke into smithereens.

It kinda kicked my butt but I’m determined to figure this out!

Until next time!
