Melting a silver alloy in a boosted fire #2/3

[clubdore]

Whats that black stuf drifing on the top of the liquid zilver?

@clubdore

oh, that were just pieces of charcoal, I did this in a fire of pieces of residual lumber

[clubdore]

@desinfector Now I see it. Yesterday I meltet some Zilver my self but there was some black stuff in it I cant determine what it was, some black hard stuf mix in the zilver. Tomoro I give i a new try, might post a vid respones ;) Cheers

When you melt gold is there anything your supposed to add to it while its melting? I always see these people adding soming to it but I dont know what it is.

[desinfector]

here I did not add any liquifiers,

this was just a test which temperature I can

reach without using special equipment.

A common liquifier is borax.

[beamerboy325e]

Thank you!

cool

Where did you get the alloy, and is the exctracted silver worth much?

[desinfector]

I got this from several sources.

until 7yrs ago I had a small junk-yard

for electric devices. There I took it from.

Any electrical switch has some silver and sometimes even gold in it.

Extracting silver (in a household) is only a little more than covering the costs it needs to extract it :-)

selling the raw metal is just the same.

[SmiertSpionem]

I heard that there is a lot of gold in computers along with other nasty chemicals.

[desinfector]

yup there's some gold in Computers, but not very much.

The Pins in any connector (which are golden)

have a very thin layer of gold. The basis is normally brass of copper.

[desinfector]

...normally brass OR copper

[SmiertSpionem]

they say that silver is the best conductor, many times better than copper (but far less economical) :)

[desinfector]

Yup, only the switching parts are made of Silver, and silver-alloys, sometimes covered

with gold (very thin layers)

This is due to the sparks that can occur during switching. A normal piece of copper would burn off in quite a short time.

The normal conductors e.g. in a cable are made

of Copper or Aluminum.

On PCB (circuit-boards) the conductors are

always copper.

[SmiertSpionem]

Thanks now I understand ;)

pretty cool...next time, wipe the dross and slag off top of metal prior to pouring. It will produce cleaner metal...(from a foundryman!)

[desinfector]

Umm, yes, thats right.

But I wanted to have the slack as well.

The slack contained silver as well and it had to be galvanized, too. Later that block produced here was an anode containing silver, copper, zinc and even gold. This procedure had to be as cheap as possible...

[TheMojoTribe]

hi not critosizing looks good but you should rely get a long pole or something like a fork and remove the slag from the top of the crucival befor pouring!

[desinfector]

Hi. Ok a long pole was missing...

but the slug was no problem, after melting this

I purified the silver using electrolysis.
