Fuming wine glasses .

[D. dino i ninjah]

I have been making wine glasses and fuming the outside .. with gold and silver . Not trapping at all just coting the surface .. I know that gold has issues sticking on its own. So I fumed with borax before fuming with gold . Long story short .. the fucking gold fuming is still wiping offf. ( I found this out as I cleaned a large order to ship today . )

Any way im pretty bummed . The cups are all fine except the gold fume basically washes off . I cant sell them ..

So how can I stop the gold from wiping off. I was making the cups . Then fuming. Perhaps today I will try fuming with borax then gold . Then shaping the cups . I know there has to be a way to make it stick

Thanks

I think you have to encase the gold.

[LowTideGlass]

You should be able to fume without incasing it and not have it rub off. Perhaps the goblet is not hot enough so the gold is not sticking permanently?

Just look at some of Jason Howard's work. He has gorgeous fume that I'm sure does not rub off.

I don't really use gold anymore. It is too expensive. I do have a female sculpture that I made out of cobalt and fumed with gold. The gold did rub off. But I also mostly made pipes with it. I would do a wrap and rake with red or something like that. The raked part would stay gold fumed.
I have no idea how jason howard does it. I see the goblets you're talking about. They are nice. I think I met him once in Corning at a Emilio Santini class. He is really talented.

After fuming with gold you can "fix" the gold with a little silver. Use a very oxidizing flame so the silver doesn't "develop" and fume on a subtle amount. Try it on some practice pieces first, it's a fast learning curve.

Yea it deff needs silver or borax .. I have read jason howard talk about borax . And I thought I had it. also some people fume figurines in gold and it stays.. Im going to try fuming the borax then gold then shaping ..

Just for clarity . The gold stays on through out the process but after annealing it washes away . In thr sink

just be careful with the borax, it's flux and will change the coe of the surface of the glass.
on a side note, it's actually quite fun mixing more borax into boro and watching the glass drip like water, I played around a lot with that stuff back in the mid 90s when I was making my own colour.

[D. dino i ninjah]

Yea I use it for mixing color pretty regularly the silver will bond to the surface really well on its own . But gold needs some help...

I tried using borax on fumed honeycombs at one point and got a slight yellowing of the glass and cracking . From using too much. But I believe it acts as a flux between the glass and the gold helping it bond .. I just cant get the application or point in the production where its supposed to be used right ...

Oh well nothing in glass has ever worked good the first couple of times ive done it .. thanks for the replies though I appericiate having others input .

Ok soo I fumed borax then gold then shaped .. it sticks a little but nothing like what im wanting ..

[HerbChambers]

Ive heard you gotta bake the gold in with a super hot oxy flame. not sure how accurate that is though..

[toddscocoa808]

Fume then "lock" it down with a cooler reduction flame

Yea im actually fuming then shaping . So its getting plenty of bake on .. or lock in time. I am starting to think that its either the 24k or the brand of clear im using (sba )

[unfunraygun]

You need to use 22 karat gold.

[unfunraygun]

22k is oldschool jbd surface tech

Thanks ray

Try using a diff source of gold that is not 24k. I think the impurities in non-24k help the gold to stay stuck.
