Davide Penso "Blow Beads"
Has anyone tried Davide Penso's style of blowing beads on the end of a Carlo Dona pipe and jacking them down with Diamond Shears? If you're not familiar, he has a video on tube filmed at Corning Glass showing his technique. I can't do it. Any suggestions would help.

Use of the blowpipe is at the last part of the demonstration. Starts at 34:50 (complete demo is about 52 min long). |
I've done it but without diamond shears or jacks. Well my tweezers became my jacks :)
The hardest part is getting the holes/ends the same. Simple soft glass etched transparent blown beads. https://instagram.com/p/6n5na9nDUl/ |
Hi
This way of blowing beads is the traditional way here in Venice and Murano. Any lampworker here use the same tecnique and the blowing tube. It's a very funny tecnique once you have mastered a little skill in being fast. A blown glass (either beads or globets) cools down very quickly and you have to pay way more attention in heat control. The basic trick is that glass and the blowing tube should have the same temperature before blowing (so when they have the same color you are ready to blown) and then if you want to make a complicate design, and you need more time, pay attention to keep warm the bead but also the blowing tube :)

I took a class with Davide 2 months ago. I found the technique very difficult to master especially in knowing when I had the small bubble in the glass.
|
Dona, Thank you. I think I wasn't working heat into the pipe, only concentrating on the glass. Can I ask why diamond shears and not jacks are used to jack down the end?
|
Udona, not Dona....auto correct. Sorry
|
bbisker, Did you enjoy Davide's class? I really want to take one from him
|
I enjoyed the class. I just wasn't good at it.
|
I am able to get the blown part but cannot use the shears correctly. Does anyone have suggestions on the correct way to get the hollow off the blow tube. So frustrating.
|
Why does Davide use a diamond shears rather then Jacks to jack down the neck of the bead?

Aja is now blowing hers from the end of a tube as well,
|
There is a very subtle difference in her blow beads and puffy mandrel beads. She's able to achieve a perfect round with the Venetian method. Her earlier designs have a very slight elliptical shape.

So, I'm still curious why Davide uses diamond shears not Jacks to jack down the neck of his bead. Any thoughts? I want to take a class from him so badly I can taste it.
|
Davide Penso may be teaching a class at bead camp in Nokomis, Fla in July 2017.

ohhhhh I'm in!

I worked in a hot shop last year for about 6 mos, as I wanted to learn how to make really big, curved beads. Didn't happen, but I learned a few things.
Returning to my torch, and 104, I learned to make pipe blown beads. My biggest problem is with debris on the pipe getting on the bead hole. Unlike furnace pipes, stainless blow pipes seem to need to be glass free from one bead to the next. Some of my experiments: Attachment 161965 This is a good little video that answered a number of questions for me. https://youtu.be/SgaN1q4enk0 |
Megan, those are amazing!!!!!!
|
Wow! Those are gorgeous beads. What kind of blow pipe do you use?
|
Soooo Megan, do you jack down with diamond shears?
|
Hi, the diamond shears (or round shears) is used because with this kind of shears it's easier to cool down the "neck" of the bead in a even way and it may help to prevent any crack when you take off the bead from the blowing tube. As you know, with this technique you work with a very tiny glass that cools down very quickly and you have to do whatever you can to prevent termal shock. Also with a round shears it's easier to have a nice and round hole. If buying a professional diamond shear is too expensive in the begining you can try a cigars shears ( they are made of stainless steel too and have round blades).
|
I'm using a ss tube and a blow hose. It is smaller than 1/4".
|
I'm glad y'all liked the beads! I'm thinking I might try mini-jacks, as the diamond shears are kind of clunky, even though they're small. Sometimes they touch the bead, and there ya go.
|
Megan, that's the problem I'm having I think. The diamond shears touch the bead and chill it and leave a flat end. I was wondering why mini jacks aren't the tool of choice.
|
Or a necking tool. I'll be trying both at some point. I need to figure out an adaptation of the gaffer bench technique for the torch. My bench is pretty messy, so that will be an issue. LOL
