These are from a tunnelbar machine. They're nice too. Melted in nitrogen atmosphere in machined graphite.

hi i know it's out of topic. can i ask how to make those? where i can find the step to make it or the machine?
in my country we just used traditional ways without safety or else
and the best i can get is just shinny top but not smooth on surface like that
people like that kind of gold because the appearance is good

My first poured bar. Think I need to get the graphite mold hotter.

It looks better than mine, I still need to get a mold,

That's not bad at all. Personally I'd heat the gold more before pouring it over- let it turn a bit brighter in the crucible if you're using a hot enough gas. Otherwise it's pretty good.

Keep the torch flame on it during the pour & make the pour just a bit off center of the mold

Its still a nice bar though 8)

Looks good brother!
What did you melt it with sir?

 

[Refining Rick]

I used a mapp torch and melting dish, with a propane torch on the graphite mold. Think I’ll do mapp on both next go. Thanks for the words of encouragement!
