fuming gold with a gtt

[Swim]

I cant post in higher learning, so I had to make a new thread. Not sure if cosmo will see this or not, but I think I have some answers to help you with your problem. Gtt has that "push" that is associates them with an oxidizing flame, but its not (at least at the pressures I work 35psi oxy vs 12psi pp). Cut the propane alot. Cut the propane more than you think you need too. I am not sure if this will fix it for you, because there is no doubt its easier with silver on a gtt, because of the reducing flame, but a medium heat high oxy flame should get it kicking a fume onto your glass if everything is hot. I am curious to know if this helps you out man. Just seems like it has to be a flame atmosphere issue, even though there is a fairly wide range of flames that with fume both gold and silver.

I was thinking about making a similar thread. The GTT user manual says how to fume gold and silver in it. On my lynx I use a bit of propane, almost close the green, and keep the blue open a bit. this makes a half inch flame, pencil skinny flame, with a little yellow at the tips. This seems to work consistently for me in getting some good gold fume. So mostly propane and outter oxygen, but not alot of either. Should be a hiss but not too loud.

[QUOTE]If you want a very small sharp flame make sure the Green Valve is Off. Use only the Red and Blue Valves. Just work in increments between the Red and Blue Valves to get the flame length you want, from 1 inch long up to approximately 10 inches long. The smaller lengths are for detail work and the longer lengths for inside-out working on the Red and Blue Valve settings. Always keep the flame tight and focused. Do not run a soft flame, except for Silver Fuming when you run the flame length out to about 6 inches and soften it up a little (cut back on the Blue Valve a little). For Gold Fuming, keep the flame tighter. Watch for any orange glowing on the burner jets or face of burner. If you see any, add more Blue Valve until they stop glowing. This is mainly when running shorter flame lengths./QUOTE]

its been a while since I had any gold, i have started doing ISO work since the last time I had gold, I would like to use some in that application. Its one of my favorite looks. ISO gold fume trapping. makes my mouth water.

I want one of these canadian coins that Jason Lee was talking about, or some panned river gold. i am thinking that I have never had high quality gold or silver after reading that.

[Captain Glass]

I have a mirage and fume gold and silver every day. I've read what GTT says to do as far as the gold fuming flame and I think there are definitely more than a couple flames you can do it with. Ive also used the Canadian maple leaf after reading the thread j.lee posted in and I didn't seem to notice that major of a difference but I'm sure he's doing things on a much higher level and is able to get effects I am not. But for the time it took to find and get the coin shipped and everything it was quicker to go to my normal jeweler and he gives me the gold grains that are already almost perfect to put straight on a rod without having to snip anything.

Thanks for posting this. I think I'm still in the premix mindset where you just crank the heat up and go with it. The gold I'm using is this - http://www.mountainglass.com/Gold-Wire-99-9-Pure-1-Inch-22-Gauge.html#.VlRnNHvci0Y

It works well. I was able to get good gold out of it. I could even get a good heavy shiny gold without much effort like this:

I have no doubt a GTT will do that too. I'm sure it's just user error.

I use my gtt to fume gold but I also enjoy using a small premix also . It's not that I can't fume on my gtt's , it's one of those I always have a smith type or natty going and rather than adjusting the bench torch I can just use the hand torch .


Actually I use both . More of a whatever strikes my fancy .

I have never done extensive testing .

[istandalone24/7]

i will admit i like fuming on a premix better. but....i haven't much experience with either, although i can make fume work on my mirage. i just can't duplicate the results easily.

[Captain Glass]

I've been wanting to try and fume with my hand torch I just need to go to harbor freight to get the lil stand thing.

[istandalone24/7]

wire coat hanger and some screws/washers. instant stand.

I'm not a owner of any blue knob gtt's .....

But I thought all valves need to be cracked at all times to keep it from melting down?

I understand perhaps a few seconds to fume, your post implys its great for lots of things, and longer periods of time.

Perhaps your quote , was some one from another thread (need more coffee)


P.s. Herb, are you related to the car dealer? I drove my brother out to Boston to buy his Yoda, still has the herb chambers badge on the rear hatch.

[istandalone24/7]

so long as you're not running super short candles, generally a triple mix gtt can be ran w/o any blue knob at all. i do it all the time.
but if it's a soft lazy flame, it will heat the face up and ports will glow. if it's a good sized flame with enough oxygen, you can totally leave the blue knob out of the equation.

[HerbChambers]

Yeah I definitely dont keep it like that for extended periods of time, dont want my torch face getting too hot. I also dont completely close any of them though, theyre all cracked no matter how slightly. I only us this flame for fuming as my lynx can get tiny flames of most types. The quote is from the GTT user manual. Haha and no, no relation to the car dealership, just a little play on words. herb.. chambers... :D my real name is actually Tom. Lemme get that badge for my hood though! just kidding!

[jr23]

if all three had to be on I would have already destroyed ever gtt I owned . Lol

You can run red / blue only on your center for limited time .

And you can run red / green on your outer for as long as you want .


The green is the main cooling . Running a tad of blue is recommended to keep carbon down .

the tad of blue keeps carbon buildup away .

[BORO]

I thought it said " no green , only blue and red" I'm not doubting anyone, especially the owners manual.

I just keep remembering t-rex and his poor phantom his lady ran wrong.

Only looking for clarity, and you guys gave it to me.

[HerbChambers]

Id take a picture of the flame, but I'm currently out of oxygen. Best of luck with finding the right flame! Whats this ruined phantom im reading about?

[BORO]

My apologies, it was user H1jacj3r... or his lady anyways.

I think I mixed them up , because they live relatively close to each other...

[HerbChambers]

Interesting! yeah I wouldn't think id be an issue though since gold loves oxy. Id think the amount of oxy needed to fume gold is enough to keep the torch cool for short periods of time possibly?

[PyroChixRock]

I would be more worried about running flames too long on a gtt.

Yeah this is what I am thinking. The bigger the torch the more you have to pay attention to this. i had trouble with the outter ring of a delta elite when I first got it, and I called gtt, and got to talk to one of the two guys that makes the torches, and he said to try to avoid orange in the candles. As long as you are not slow rolling the big soft candles, i think your good to go on any gtt. If you get out of the safe range of flames, the torch starts fucking up pretty quick, to much gas and it will internally combust, which is scary, and bad for your torch, but not a game ender.

[hammer]

I mainly fume on the lathe and believe it or not, my Nortel Ranger hand torch (minor) is my favorite fuming torch.

I also got good results from my Lynx but it's not as easy as the Ranger.

Im excited to hookup my smith little and try that out for fuming. Although I doubt too long of candles would be an issue while fuming, especially gold, but maybe not.

[Swim]

Your gonna like the fume off the smith if you get the blast shield tip

[HerbChambers]

Yeah I'm gonna invest in some tips down the road. I'm mostly excited to use this to burn off excess fume though, I hear it works great for this.

[Cosmo]

Finally figured it out. I was just getting it way too hot I guess. Turned the flame down much lower than I thought it should be and it worked like a charm.
