Goldilocks - move the punty

WRG finding a place to heat up the punty:

For certain, too cold is NOT OK.

Too hot, well, there are things to do about that - Simply pull the punty away from the heat. Of course, to far, and it will crack, to close and it slumps and makes a mess. But at least it's in your control.

You know it's too close when it moves.

The makeup of a "G-Punty" helps it be more robust:

- coat only the bottom 3/4" of the punty
- Very thin on the sides - maybe 1/16"
- About 1/8" on the bottom

This kind of punty can get relatively cool without cracking.

Thanks for the dimensions it helps answer some questions. I have more glass on mine so when I heat it from the front of the GH and it gets ripping hot, the glass drips out. Hopefully the thinner layer of glass will not run off when it gets very hot. Itís easier to cool a hot punty than heat it up.
Eben if bill punty drives Lino crazy, I am mad for sure.

My measurements in mm were referring to the amount of glass off the pipe.

Build that rack! It will help you immensely. You could even cut a rectangle out of your glory door so you can slide the punties in there. Like Bill's.

You are definitely on track with the puntie you posted, except it is round, instead of flat at the tip.

And Bill would probably say you need to dip the iron or blow pipe half as deep. The glass on the puntie is too much. Your setup might prevent this however.

Looking good!

By the way, I kept butting heads with my girlfriend when she was learning Bill's technique from me. She kept wanting to skip steps, combine them etc. Follow the recipe for success

Another exercise Bill did was to practice gathering with a vat of honey. It has basically the same consistency as glass. That helped me out quite a bit.

the honey is a great idea for practice. I wasted well not wasted but use up lots of glass practicing and was doing the wrong thing over and over. I started out goodish and slowly lapsed into chaos. Back on track now.
Btw, honey is $100.00 for a bottle here. We not allowed to import honey.
So Michael hinted that I could use sugar and water. My GH is small. I welded a bracket to the door and welded rack on bracket.
Rack installed in front of door. see pics. The hole in the back did not work good. Too cold.
More testing tomorrow.

I reuse my punties most of the time. It stays about the right temp in the pipe warmer. Working alone I can keep the blowpipe in one hand, punty in the other, thirty seconds in the glory hole and they are ready to stick up.

Thanks Ed. That is what we want to do. But by the time I heat up the punty pick up the piece from the hanger things start to fall apart. The timing and temp has to be precise.
So instead of heating up we cool down. This saves time for the Punty up and transfer.
Sounds easy . Ha. The next stage is to practice the punty up in one smooth motion. Accurate and spot on.

Franklin: Part of the reality here is counter intuitive. Really small pieces are in fact a lot harder to make than bigger ones. It's just true.

Steuben trained their new people on miscible oil/ Cold Molasses would work.

I think that's true in the beginning but my joints and muscles say otherwise. I have a hard time now with anything thick I can go thin even walled without thought but to make thick organic is just going against the grain.

I had to look up "miscible". One thought I had is -- why couldn't have Corning saved something, anything from Steuben in its new facility.


Franklin -- check this video out. It has a pretty good shot of the puntie coming out from the rack (an assistant certainly helps). It might take me a couple more days to find my videos.

His assistant didn't bring the greatest one either.

It would be nice if they used noise-canceling microphones when they make these videos.

Rich remember when we started on this board many years ago. I would have died for 5 minutes of video . Whitehouse had it all. Now they have disappeared and we have grown accustomed to numerous videos on YouTube.
They are the only ones I trust as not being fake. Oh sh... I hope they are real. With fake stories everyone looses.

Lifting the small pieces is certainly easier but starting with busting a hole with the punty on the bottom of the piece to all the other processes are torturous.

Just looked at the video Max. I can appreciate it more now. Thanks. Do you know if anything in his process changed from that time 2002.
Pete I was wondering why things were going good then after all these years it fell apart and I did not realize that I gradually creeped into making thin pieces.
Thanks for identifying it. Busting out a chunk from the bottom of a thick piece is no big thing. 😬

Lead. It pervaded the facility after all those years. I think the really big loss was the grinding and polishing equipment that was all remanded to the dump. It would be curious to know how they pulled that off. I don't have a clue as to where the mixing equipment went.

Both small and small and thin lose heat really fast. The other issue there is how difficult it is to simply heat one part of a tiny piece. If it's under heated it puts enormous pressure on the punty when you try to tool it. From my point of view, if you are making things with two gathers or so that you should do what needs to be done before the glass loses its core heat. It works somewhat better in colored glass since that at least absorbs IR. Clear reflects it quite well.

If you have a good grinding shop, divots don't matter much. I don't do punties the way most people do anyways.

Igneous glass bought up all the Whitehouse inventory. I don't have a clue what remains.

Actually the oxygen/ gas torch did away with a lot of cold work, forget punties.
You can pick a stone or bubble right out of a comleted vase

Anyone know that is the temperature in a pipe warmer.

Thanks

Yes, from pulling the glass out, pull it back in toward your body so the thread wraps around the hot moile as you turn and the heat cuts it for you.

I haven't been able to get on my old phone with the videos... sorry

Thanks Max. I am working a bit cold to cheat and get a bigger gather. but will have to increase the temp.
found some good videos on the Corning site.
