In this Instructable, I demonstrate a way to make your own jewelry from glass bottles.

What you will need:

  • Microwave kiln
  • Glass bottles
  • Jewelry blanks (rings without the stone, end hooks etc.)

You will also need a kiln paper.

You could buy a special glass that comes in all colors you could want, but there is a cheaper option.

You can melt the glass from the bottles to make your own jewelry.

It is also a great way to upcycle glass bottles.

Step 1: Get Your Glass

In the previous Instructable, I demonstrated a way to drill a hole in a glass bottle.

I kept the glass circles so I could use them to make jewelry.

You don't have to use round glass pieces for the jewelry, you can just smash the bottle and use the pieces as they are.

I used 4 different color bottles to cut out the circles for the jewelry: Green, another shade of green, white (transparent) and blue.

Step 2: Prepare the Kiln

Put the kiln paper in the kiln. It will prevent the glass from sticking to the kiln as well as protect the kiln.

You can mix different color glass for different effects.

I put 3 different color circles in the kiln.

My kiln was damaged in some areas, that's why I did not put the glass in the center. Normally you would put it in the center.

Step 3: Fire It Up

Put the lower part in the microwave and after making sure the glass is positioned the way you want it, put on the top piece.

Turn on the microwave for a few minutes on a high power.

Time needed to fuse the glass will vary depending on your microwave, size of the kiln and the glass you use.

I need around 5 minutes to melt the glass.

You can check the kiln every few minutes or even seconds to see the progress.

When the glass has almost melted, check the kiln after every 10-15 sec.

Just lift up the top piece and have a look.

Make sure to wear gloves and goggles.


Step 4: Cooling Time

When the glass has melted, take out the kiln and leave it to cool down before opening it. (around 20 - 30 minutes)

Make sure to put it on a heat resistant surface.

In the picture you can see the glass when it's hot and when it has cooled.

Step 5: Attach the Glass to a Blank Jewelry

Now you can attach the glass to a blank jewelry.

Rings, bracelets etc.

All that jewelry was made from glass bottles.

<p>Very cool project, thanks for sharing! Can I use the same microwave that I cook food in, or does it leave chemicals behind that would contaminate the food?</p>
<p>I use the same microwave for food and glass - just make sure you do not use any lead based colors. It has been a decade or so since lead has been banned from any food-related containers so it would only be introduced by adding colors.</p>
<p>Some kiln manufacturers recommend to use a different microwave for the kiln, some say that as longs as you clean it properly after every use, there is no danger.</p><p>So there is mixed information.</p><p>I personally don't see any danger in using the same microwave for the food as long as it's properly cleaned after every use. However, if you are planning to use the kiln a lot, I would definitely get another microwave.</p>
<p>Be careful mixing the different types of bottle glass that you use for this kind of project. The coefficient of expansion (COE) may range anywhere from 40 to 88 or so. Basically it means that the glass at 40 COE expands and contracts at a different rate than the 88 COE and the pendant that you made could crack, break apart suddenly or shatter. Yes, you might get lucky and get a couple of pieces of glass from two bottles that have the same COE, but unless you test the glass, you cannot be sure and would be advised to avoid gifting Great Aunt Midge a hand-made pendant or selling your extras unless you've tested the glass. There are instructions on the web as to how to test a glass' compatibility with another.</p>
<p>I was just going to say the same thing. I did something similiar when I was just starting out and had the necklaces literally explode on people's necks...sometimes months later. Only use 1 bottle for each one and do not mix please! it is highly unlikely they will have the same CoE!</p>
<p>All you need to do is run some COE tests - pieces of each color/kind of glass fused and cooled then take 2 polarized lenses and rotate them so the no light gets through then look at the glass with light behind it - the lenses will allow no light through unless the glass is stressed. Stressed glass will bend the light so that it will be visible. My very first glassblowing project is a paperweight - I think that is the standard first project - has a stress fracture in the center of it. I have been watching the fracture and it has expanded by about 2 centimeters over the last 10 years - I expect it will crack/shatter in about 20 years.</p>
this is a test to see where it goes
I'm all for testing and finding out the limits of glass and what you can do with it with what you have. My nephew was fond of melting glass and then watching it pop when it cooled. <br><br>I've been fusing glass for 15 years or so and I've seen one too many people melting stained glass together and trying to pass it off as something that will last. Or taking bottle glass and melting it without annealing it properly. <br><br>I've seen people melt bottle glass into cabochons. Some of the bottles with printing on them are real interesting because the paint that's used is fired on and can often survive being melted again. <br><br>And if you want to be real scientific about it, keep a log of your fusing schedule and the results. Like I said, have fun!
<p>I looked around a bit and found nothing diretly related so if you have a link that would be nice . Thanks</p>

<p>THANKS!!</p><p>there are days when this site leaves me wondering who coded it and why....do thenk in linear fashion or in some strange multidimentional one. I hit reply and cannot see your reply, I see the comment that causes me to reply to whit you replied to my question......aaaarrrggghhh charlie brown.</p><p>Thanks so much for the links</p><p>Maybe I will earn some Sparkie Points!!!</p>
<p>Ditto! I have a whole box full of failed pieces from when I first started fusing using scrap bottle glass that I keep to remind me to test first.</p>
<p>Thanks for the info.</p><p>Very useful!</p>
<p>how do u attach the pendant holder, if making a necklace? Glue it to the already cooled glass? And what type of glue would you suggest, crazy glue? I really wanna try this...of course I gotta click the link on where to buy the kiln, praying its not expensive! Lol</p>
<p>Hobby Lobby I saw a microwave kiln there for around I think 100$ I'm going to get me one Hobby Lobby often has coupon in paper for money off your total purchase I think like 40 percent hope this helps.E-6000 glue</p>
<p>The price is now down to about $30-40 for the large kiln.</p>
<p>In the video I used a super glue, but it's not the best option.</p><p>I find that 2 part epoxy glue is one of the best choices.</p>
<p>Whole lot of good information here from you and the comments section. Thanks for this.</p>
<p>darn, $50 bucks for kiln &amp; paper...gonna hafta wait til after Holidays....</p>
<p>O YA!</p>
<p>Can you use a regular kiln? If so, would the prep and time be different? I am anxious to try this out but don't want to buy a microwave kiln if I can use the one I have. Thanks.</p>
<p>Yes. Position on kiln paper or a well kiln washed shelf. Heat to 1250 to 1450 degrees, depending on the form you want. Then let it cool - open for a moment then let cool to 900 and open again for a moment. Once it reaches 300 you can open and leave open. </p>
<p>I guess it does not matter, but I have never used a regular kiln, so it's just a guess.</p><p>If you try it, please let us know how it turned out.</p><p>Cheers!</p>
where can you get a kiln thingy for use in a microwave?
<p>You can get it from eBay, Aliexpress or Amazon:</p><p><a href="http://amzn.to/1O1wlCg" rel="nofollow">http://amzn.to/1O1wlCg</a></p>
<p>Always resourceful and I bet you do not throw anything away, HAHA!</p><p>Thank you for your great intelligence. </p>
<p>Thanks!</p><p>I do throw things away. American Pickers will not visit me any time soon.</p><p>Maybe it's because I live in a small apartment, so there is not a lot of space to keep stuff :)</p>
<p>HAHA. I understand that. But i see you do not waster anything as well. A good character trait. </p>
<p>Can you use a regular microwave?</p>
<p>Yes. I used a cheap regular/kitchen microwave.</p>
<p>OHHHHHH YEAHHHHHH!!!!</p>
<p>Can you use a regular microwave?</p>
<p>Will let you know how it goes when I try it. Just got the kiln so I need to learn how to use it well before I experiment. It will be my summer project (my winter is packed with projects). </p>
Great instructable
<p>Thank You!</p>
<p>Nice, This reminds me of a project I made at a camp about 3 years ago</p><p>It's a turtle made of broken glass bottles, You might recognize the outside which was made of coke bottles</p>
<p>Nice! It's like a large coaster.</p>
<p>It isn't totally flat, But if I put it upside-down, Then It could work as a coaster</p>
<p>I think you can sell this jewelry on etsy or something like that, I looks really cool :)</p>
<p>Thanks!</p>
Didn't know you could do that. Great instructions.
<p>Cheers!</p>
wow this is amazing. I had no idea a portable kiln existed.
<p>Thanks!</p><p>Yes, they exist and they are great (for jewelry making)</p>
