Why do you make your second gather cover the entire first gather.?

So it is easier to keep an even bubble in your piece.... that is, if that is what you want ;)

Thanks. I want to cheat. As the glass in the pot gets used up I get to the point where it is not feasible. So I gather half way up and shape accordingly to make it even.

use a round bottomed pot.

Further, not gathering completely over makes for a very difficult piece to neck down unless you have other design goals. Even further than that, the piece now has really different temperatures in it, some hot, some not so hot. I tend to think it makes progressing in skills difficult.

I knew somehow I could not get away with it . Did not realize it was so important.
If it should happen by accident (sometimes I miss the gathering mark) Can I save it if I heat the piece with uneven gathers ripping hot .

I have a couple designs where I make my jack lines then post gather over half the piece roll in color and go.

There are no rules Franklin! If you do things like this your work will look a lot different than a classically trained glassblower.

I feel your small-pot pain Franklin. My first furnace used 20lb pots that were designed for ladling steel in foundries. Tall & skinny, with a flat bottom.

When I got to the bottom of a pot and wasn't able to get full even gathers anymore, I had the most luck with just doing multiple small ugly gathers to get the total amount of glass I needed, then reheating everything (it's a looooooong reheat) and blocking to even out the form before blowing in the initial bubble. You're not going to make perfect pieces that way, but it lets you use up all your glass in the pot.

Eric thanks , Itís nice to have someone who understand the woes of vertical gathering . I plan to pull cane or make marbles / paperweight when I reach the low limit.
Sky that is exactly what I try to do . Sometimes I loose the jackline but I heat up the neck in the burner flame and bring it back. I have to be careful I donít blow out the bottom but by gathering on the end helps with a thicker bottom.
Eben all I want to do is blow glass but I have to work with what I have for now. You make me so very curious with your answer.

I think that it's fine to do things when you have a specific design goal in mind. That happens lots. On the other hand, doing things when you don't really recognize other options is maybe not quite so good.

Clearly to me, the main way one learns is by trying to duplicate work that one sees and admires. That allows you to measure yourself against a standard. The goal after that is learning to speak with your own voice and that's a lot harder.

I totally agree Pete but When I deviate Its because my limitations causing me to search for another way.
I hear you when you say glass remembers what you did to it so I expect trouble and that is why I ask all kinds of crazy questions. Its not that I donít want to do it like the teacher. I donít want to fix the unfixable, but I want to recognize the unfixable. It may take longer but for now I just want to box it.

Nonsense. Dont count yourself out based on what others say until YOU know it to be so. Always question and experiment as much as possible.

I try. Solving the punty problem will make all the difference.
Thanks

That being said, there are pieces that can be made by "posting up" a piece. Take your first gather and put a solid jack line in. Gather 1/2 way up and work the bottom/thicker glass as you normally would. Punty-up and open. This way, you can also get a thinner neck because it only has the thickness of the first gather.

Mark you certainly know how to cheat. I note the jackline comes early. Do you blow it and put in the jackline with the first gather?
Thanks

Always blow out your bubble to an even desired thickness. With only one gather, you can go back with a good heat and put a jackline in..... p.s. it's not cheating if it works! ;)
