I have received and learned so much from beadmakers on this forum when I started a few years ago that I feel happy, now that I have some experience, to finally be able to kind of give something back. So before I start this ring tutorial, let me just say a huge thank you to all those who have given here so generously their tips, tricks, tutorials and time.
Last year I took a class with the italian artist Diego Bottacin on rings. This one of the numerous ways he showed us to make a ring. A few months back, after having checked that it was ok for me to use, for an on-line tutorial, what I learned in the class including the pictures I took, I wrote it for the french beadmakers forum (very small community : about 130 members, but the beadmakers movement only started 4 or 5 years ago over there, the forum opened two years ago, and very little infos are available in french. Still, it is very nice to be part of it from the beginning). So here it goes, and this time in english :
You will need :
A big hole mandrel (bead release free)
A clamp (in order to fix / attach the mandrel to your working table)
A 10 mm glass rod of any color you like (a 10 mm works better but if you don’t have it, you can take 3 smaller rods and tied them together at one end with an elastic band : not as good, but it will do the trick)
diamond shears (nice to have, but not mendatory : you can find a way around it)
A marble mold or something similar
A fairly large masher
A tweezer
Shears
And a hotfinger
The trickiest part is going to be heat control and working speed (for this, fast is good). And again the 3 Ps rule applies.
On the pictures, you’ll see Diego Bottacin use a special italian tool (but I don’t know its name in english, maybe it’s called a ring mandrel or a ring stick ?). It’s a nice tool to have (but fairly expensive), because it brings your working area to eye level. But you can replace that by a big hole mandrel clamped to your table. Just be a little bit careful : after one or two rings, the mandrel gets hot and since it might be in your way when you get up, for instance to put the ring you’ve just made in the kiln, and you might burn yourself.
Now, take your glassrod and melt a big glob of glass, about 1 inch or a little bit less in diameter.

Then make a neck with your diamond shears where the glob and the rod meet.
78109
Put the glassball back into the flame, get it evenly hot again. Next, you just want to slightly cool the surface. So you roll the glassball in the graphite mold (this step can also help you to realign the ball with the rod a little bit if needed).
Then, just squish the glass ball flat with the masher: you now have a lollipop shape.

But the shape you need to have is more the shape of what I call a « calisson ». What is that ?! it is a typical almond french cookie, it tastes really good and looks like this :
78111
So what you need to do, is to pull a « point » opposite to the rod with your tweezer. You now have the right shape but the glass is not warm enough any more. Reheat the « calisson », one side at a time. The faster you have worked, the less you will need to reheat, and the better because you want to retain a nice « calisson » shape.
78112
Now grab with your tweezer again the point of the « calisson » opposite to the rod, and place the calisson under the mandrel. Center it, lift it untill it touches the mandrel and close it to form the ring. The heat should be evenly distributed in the glass and you should pull with just the same strength and speed on each side.*
78113 78114
Remove the ring from the mandrel. Grab the ring with your hotfingers. Just heat the rod real close to where it is attached to the ring. Remove the rod. Then carefully heat the part where the ring was closed and cut off the excess glass. Heat that very spot to make it smooth. Put the ring in the kiln and voilą ! Or as Diego would say : e basta !

*Trouble shooting :
When you want to close the ring, you might be facing three problems.
• Once the glass touches the mandrel, it cools quickly. If the glass is too cold, you won’t be able to pull the glass and close the ring.
• If you’re glass is too hot (you’ve started pulling too soon), the ring will be too thin / narrow except for the top center part.
• If you’re pulling uneavenly, or more likely, if the heat was uneavenly distributed, you’re ring won’t be symetrical : one side will be broad, the other one narrow, and the center part might off.
A last little piece of advice : at first, don’t to make a fancy ring, just try to make a plain ring, I’ve found it difficult enough. And remember it’s easier to start with a transparent color.
During the class, I totally forgot to take pictures of Diego’s rings (it is a shame, since they are so beautiful) so, instead, here are some traditional examples (with gold leaves or silver foil) of Murano rings.

And one of the very first one I've made:

I hope this tutorial will be helpful! If you’re very interrested in making glass rings try to take a class with Diego : he is very talented and there is a lot more to this class than what I’ve just reported (I believe he is going to the gathering this year). And don’t forget to post pictures of the glass rings you’ll be making !
