Free lampworking tutorial – Pulling Cane from Recycled Glass – Upcycled Glass Beads

Hi again! I promised this tutorial over a year ago and its super easy, but for some reason I only got around to it this week.

Upcycled Glass Bottle Beads are super easy to make, but I’ve had loads of questions about how to deal with the shards of glass without them shattering when the flame hits them. I tend to pull them into cane to store them and I preheat the finished cane in a kiln when I’m ready to use them.

Remember, these bottles might not all be the same COE (coefficient of expansion), so I tend to make them into single-color beads. So, your first thing to do is to get some bottles!
Lets take a look at some of the ones I like to use.

Brown beer bottles tend to make pretty scummy cane. They boil a lot. I still really like them because the finished beads look rougher, which makes for some nice “upcycled texture.”

Heinekein beer bottles are great to pull into cane. They are smooth to work with and don’t shatter easily when you reintroduce them to the flame.

White wine bottles come in a whole range of color, but I like these light olivine bottles the best. They are super creamy to work with and just have a wodnerful color to them.


These also come in a whole range of colors. The darker ones just read as black when you make a bead. I don’t use these a whole lot. The clear bottles get really scummy in the flame.

LOVE this color bottle for beads. It can be a little shocky to work with though.

Makes a clear, good cobalt blue bead.  This is the glass I’ll be using for the tutorial.


So… you got your bottles, but you know, they are a little big to work with directly. So, get yourself a box and a set of glasses and dust mask and a good metal hammer. Head outside. Put your bottle into the box, slip on your dust mask and glasses, and give that bottle a couple of good taps. I actually set my bottle into the box, and cover most of it with the box flaps. I leave just enough to see what I’m up to. You want some shards that are about 4.”

Grab those shards – throw the rest of the box away. Its full of glass dust. Remember, the edges are really sharp!

Throw those shards into a kiln and ramp it up. I work at 950, and I just ramp up at full, but if you are worried about the shards cracking, you can ramp it up at a slower rate.

Once the shards are at full temperature, you’ll pull them out with tweezers (or hemostats) and attach them to a punty. I use a 1/8″ mandrel. You’ll need to heat the punty to glow and also the shard.


Next, you’ll be heating that shard until its all gooey and starts to flop around. I actually fold it up on itself, but its really important to not let air get caught in it, otherwise your finished cane will be super shocky. Continue to heat until you have a good blob. You’re going to need to add a second punty, so you can actually do that at the beginning, so you have more control over your molten glass.

Heat your glass until its all glowing. If you haven’t already added that second punty, now is the time to do it. You want it to be evenly glowing and a good round or oval shape.

Pull your glowy molten mass out of the flame and wait for a “skin” to appear on it. Start pulling, slowly and gently. When the cane reaches and thickness you like, you can blow on that area to “set” it. Since heat rises, you’ll be able to tip the hotter area upwards and continue to pull until you have a cane. The one I’m working on here is pretty short, but its a good starting point for you.

As a side note, it looks like I’m pulling this in the flame, but it actually isn’t. Its all in front of the flame.

Break off the punties and either immediately use your cane or place it in the kiln while you make others.

Here, I’m making a bead from my blue cane (remember to hold it with hemostats or tweezers since its just come from the kiln)… You can see where my cane has cracked a little. This is because I was waving the whole thing around too long while I fussed with the camera.

And here are some finished recycled glass beads!  You can purchase these at

HAVE FUN! Now, lets see what you’ve made!
