hydrogen?

[Spinney]

Has anyone ever used hydrogen? I have heard you use it to melt quartz glass. What about using it for everyday stuff. Just doesnt seem safe or effecient to me.

it's not.

Hydrogen/Oxygen is used in quartz fabrication because it's a about 1200º hotter than Propane/Oxygen (5792ºF vs. 4579ºF), which is what it takes to melt quartz properly...

On boro it messes with color, boils the glass, and generally makes a mess of things, plus the flame is harder to see, and the tools and torches are destroyed pretty quick. Hydrogen permeates most metals and makes them brittle... plus it's more expensive than propane usually, and harder to get. The size of the molecule makes it difficult to store long term... lots of reasons we don't use it with boro, those are the main ones I am aware of.

This fellow seems to do all right with it. ;)

And this guy's setup seems to be doing okay.

Its wonderful for clear. I tried it out on boro when we used to keep a bottle for quartz purposes. Your clear comes out more glassy/shiny looking than with LPG because hydrogen is such a clean fuel. Never tried it with colour, but I assume Doug is correct there about it wreaking death and destuction on some of the colours.
Google Eddie Legus, he's a french glassblower who uses Hydrogen on fairly large rod to make his scuptures and also uses some colour. He's got some youtubes, too. Contact him and I'm sure he will be happy to tell you more.
Hydrogen as a fuel is more expensive than LPG, but the increased speed of working with it may just mitigate that.

I beg to differ. Have you ever heard of something call Brown's Gas? I'll see if I can find a link for you, it's certainly the wave of the future!

Now the real question, is it more cost effective? I mean you could just use solar and some water and BOOM! free hydrogen.

^^You sir, are a genius.

Please do post a link when you find one. I would like to know more about this, "Brown's gas".

I will be sure to save you guys a special seat in Hell, between me and Dwaine.

It's been around for a long time.

There are some bogus claims attached to it but it has some
unique properties.

Oh god here we go again........... doug is going to blow a gasket. You fuckers and your free energy crap lol........

Hydrogen is much more expensive than propane period! Go to a welding shop that carries it and find out for yourself.

I spoke with a few people recently who said that they used hydrogen for some tasks because it treated certain colors (China black?) really well, and reduction wasn't a problem due to not having any carbon in the flame. I haven't seen this myself.

Also, hydrogen's very hot flame is said to be indispensable for certain quartz work as Aussie has noted. I can't see everyone starting to use it daily, but it has its place.

[Greymatter Glass]

It would certainly be nice to colors that have problems with reduction... my reference for how it treats colors is based on one of those videos posted above - that guys beads are jank.

it's also used on herbert arnold crack off machines... tiny little pin point laser flame. Cool tool.

As for price, you have to compare price/unit of energy (btu or kcal or kJ)

Are you referring to Joseph Spencer ???

If so, maybe you should google him.

And the second guy's bead didn't look bad at all.

hydrogen is awesome for quartz, With (CLEAR) boro I wasn't fast enough to keep the piece alive, it turns to a liquid very quickly, fun for the super super experienced.

fuck hydrogen, MAPP all day, idiots.
