Mystery Blue Punty Additive
 
1 Attachment(s)
Does anyone know what the stuff is that Janusz Pozniak is adding to his punty is this video of he and Dante making a low bowl? I've attached a screenshot.

Here is the video: https://www.youtube.com/watch?v=0WGgCUVnoQs

Thanks...

P.S. If someone says "glass" just remember that karma is a b#%ch.

Powdered chalk?

Dan Vanantwerp 08-29-2017 09:10 PM

He adds it to the business end as well...would chalk allow for an easy release?
The bowl is a transparent roll-up so a punty mark would be a definite no-no.

It very well could be chalk. I've used chalk on the bottom of a vessel to find center and lost pieces for lack of sicktivity. Ok maybe not a scrabble word. Anyway it could be some straight line for a chalk box.

Sand punties have been around forever and I've seen where someone will roll on a piece of ifb before applying. Blue chalk would be my vote.

That has to be one of the shittyist demonstrations I've ever seen. Very saddening to see that as the benchmark for students now coming into glass.
So very sad.

Jeez Peter, With just a little work you could turn that into a tweet.

Eben Horton 08-30-2017 08:39 AM

chalk. you can also use IFB dust

Dan Vanantwerp 08-30-2017 01:44 PM

I'd really like to have Peter elaborate on why the demonstration is so bad? I'm using Dante's sequencing as a learning tool to make better bowl shapes. The final shape looks very good to me. They are very stoic and there is not any great display of teamwork but I'm a solo glassblower and appreciate any video I can find with less than 3 assistants.

the secret to a good low bowl is to punty it up with the bowl as hot as you dare and the punty as cold as you dare. Use a big round shaped punty with chalk dust around the edges so it won't fully stick but add support. You can make a bowl with just a newspaper by spinning the half opened bowl fast and "catching" the bowl in your paper to shape it to the final shape

Dan Vanantwerp 08-30-2017 05:39 PM

Cool...got to try it out!

I find that a fine line exists with papering a bowl and leaving the dreaded scum...it's all about the heat, but sometimes I just get caught up in trying to perfect the shape.

I like Dante's use of the parchoffis to push out the bottom and sides to widen the shape. His little floor steam puffer step is also pretty nifty.

Randy Walker had a class highly recommended to me: the 1/2 round bowl. Anyone know if he is still teaching?

Peter Bowles 08-30-2017 07:16 PM

I've had a long love-hate-love thing with bowl making over the years - and to see someone demonstrating with such disdain for the process leaves me cold.
Shitty canes, shitty gather, shitty marvering, shitty blowing, sloppy shearing, aggressive opening. It's just is never going to make a good bowl. He knew it, the team knew it, the students seemed to know it. Just very sad.

If you want to learn bowl making - look to the the Swedes and the Danes. The Scandinavian approach is way more sensitive than anything I've seen out of the Italian tradition.

Everyone who makes bowls have their own thing that they think is critical - sometimes they overlap, sometimes they are in contradiction. It's a fascinating journey. For me, its all about managing wall thickness, when I get that right the bowl helps to make its own lines a lot easier. I used to spend a lot of time chalk drawing on the floor to work through the stages I wanted all the way from gathering through blowing, and opening.

My first off hint would be to lower your yolk 50mm - that in itself will change everything.

Dan Vanantwerp 08-30-2017 07:53 PM

Thanks Peter. You certainly have the proper surname to have formed a strong opinion on the subject. :)

Seriously, though, it's very humbling for me to consider how much time many of you have devoted to your glass in pursuit of the perfect shape.

Any artist(s) in particular I might look to from the Scandinavian school. I believe Buzz Blodgett was trained by his father in this manner. He was teaching an advanced class at UC San Diego while I lived there but I never had the opportunity to attend (and I was no means, advanced). I think their program has now gone defunct.

Peter Bowles 08-30-2017 08:22 PM

Darryl Hinze, Nanna Bachaus, Tobias Mohl are all great bowl makers, not sure how much is out there on youtube on them. Stephen Dam could also make beautiful bowls, not sure how much of his practice is of that kind now.

Jordan Kube 08-31-2017 12:16 PM

I never flash the punty on a low bowl once it's on. It will stay warm from the deep heats.

Dan Vanantwerp 08-31-2017 11:45 PM

There are some nice videos out there of Nanna. Beautiful studio/gallery with her husband right on a marina. For bowls, her setup and Dante's are very different....interesting contrast in styles. Dante's shape prior to transfer has a fairly long neck and a wide bottom...like an Erlenmeyer flask. He trims off quite a bit to bring the sides down. Nanna spins out the sides while on the pipe in the glory and the shape prior to transfer is much more like the final bowl.

Not sure if this can be generalized but I also noticed how much more she kept the pipe downward. For most of the artists I've watched they tilt the pipe upward with their left hand to look at the piece (I guess) and enter the bench with the right hand ready to grab a tool. Nanna keeps it low and "swings open the gate" to enter the bench. I was taught the gate method but have been trying the other style to get my hands on a tool faster.

Like Jordan suggests, I was taught to NOT flash while working a platter or low bowl. Got to keep it square. Nanna spends a good 2 or 3 turns every time to set the punty end of a bowl. She works QUICK! Out of the glory, to the bench and very efficient. Joy to watch...she is very nice looking also :D

That's what I think as well. Diamond wheel, sand blast off the roughness of the wheel marks and then hot wax.

Justin Zotynia 09-09-2017 02:35 PM

there is a great video of boyd and lisa demoing bowls on YouTube at cmog. not enough data to watch Dante

Bradley Howes 09-13-2017 08:52 PM

I agree with the above posts, it does look like chalk.

Scott Mitchell 09-14-2017 11:21 PM

Ok, what was the point of the extra transfer after the rollup. Why go through closing the bubble, re-opening it, and then transferring to a post?

Greg Vriethoff 09-15-2017 03:14 PM

Not long after I landed in Seattle I took a three-day workshop at Pratt in assisting skills. The instructor(s) was one of Lino's main people. When we got to making this kind of punty, it was stressed very heavily that these are called "dust punties." DO NOT refer to them as "sand punties."

Okay.

I asked someone later at the shop I was working at what the deal was. I was told that the term "sand" was associated with what's done down in Mexico.

This stuff gets so stupid at times.

Dan Vanantwerp 09-15-2017 04:11 PM

Thanks to everyone for their contributions and educated guesses. I think that Greg has the winning answer though and even "named" it...dust punty. Kind of sounds like dust bunny...I like it!

Going to grind up some sidewalk chalk and probably lose a few pieces until I figure out the right amount to apply. Then I can use the chalk to outline the remains on the floor.

Pete VanderLaan 09-15-2017 05:39 PM

we used to make sand punties. They certainly work unless they don't
