Marvering

Do you Maver across then back (back and forth) or can you Maver across lift up come back to the start end the roll down the Maver again?

Back and forth. The motion starts in your feet. I like to compare marvering with Thai Chi... it’s all flowing motions.

I showed you Franklin�� initially when the glass is very hot you might go back and forth a couple of times, but then you lift to let the internal heat in the gather get back out in the skin, so you can actuallyshape the piece, I sort of agree with Eben, but Id put it a little higher up. Its a dance

The old saying was something like - Glass is a liquid, be fluid with your motions. Dance or Tai Chi or whatever analogy works, keep it fluid and smooth, which I am sure you could achieve lifting up the piece but I see no reason to go that route. Oh, and I know, I know, it's an amorphous solid, no it's a supercooled liquid, no my personal favorite ‘Glass is a non-equilibrium, non-crystalline state of matter' Which I think, is leaning back toward a liquid...

It depends on how hot it was in the first place.

There are videos on YouTube about “marvering” and “how to marver”

Angry

Yes you did Michael but then I thought what if I could cheat.
Rolling forward is much better / stronger for me to do. me. The airplane landing was a good way to explain it. So I am busted.
Eben do you have a favorite video. I don't see them paying much attention to mavering properly. Michael identified to me some basic skills that need to be mastered and which I ignored in the rush to blow glass.

"Mavering" is how they say it in Boston.

I don’t. I was marvering just fine before the internet was a thing so never used YouTube to learn. Every time you lift the glass off the steel and put it back down, you will throw off the balance of the piece.

I don't care how cold you are, I'm not sure I want to know what you and your sponge condom are getting up to

English is a very precise language. I meant when my furnace is cold . Not me , I am always hot. No more sponge. I try to do it without the condom now but maintain the air space.
I also just discovered a way to polish my marvel using a hand grinder with a polishing disk. It removes all the rust and the surface is so nice and smooth. But then again I have a disposable marver.

Ok, I'll bite. What's a disposable marver?

I am sorry, it was a poor joke. I used a piece of C beam which can be easily replaced for no cost to me.

You can get by marvering in one direction if you don't care if you twist up your bubble, don't want to improve your hand skills and want to look like a noob to any visiting skilled glassblowers (not the best reason, but still).

Marvering your glass is inherently rolling a cone and each direction tends to create a twist--really minimal if you're good, not so minimal if you're not. Marvering in both directions can keep things straight or allow you to straighten things out. I find it super useful in keeping patterns (cane or murrine) lined up or fixing them if they get off a bit. (You can also untwist to a degree in the gh, but that's a different deal).

If you want great hand skills you need to turn well both ways, so might as well practice it every time you marver.

Great advice well taken. Don’t know why I keep looking for shortcuts. Not good but if you understand why it’s like a light turning on.
Thanks David.

you don't want to rotate your pipe all in the same direction when you're walking around either.

Oh sh.....Just when it was getting easy. You never see these fine points on tv.
The result seem to be not very visible but I am sure it makes a difference in quality.

Torque is admittedly one of the lesser Gods but it can tie you in Knots.

What I still can't do is to turn in both directions on a larger piece in the gloryhole. I'm just not strong enough and it's getting worse.
