My first Au Cl with pic :) !

[Heaven's Pavement]

What a way to start the newyear than with my first Au Cl solution.
These are pins from the smart card area of cable boxes 600 to 800 of them.
Did not weigh b4 as this was to go through the process.Gold would be a bonus.
twice the volume than first started due to water spray down.
Within 5 minutes the foils went into solution.
Right now I'm doing the SMB step and alreay is mostly clear with some sort of light brown substance showing up at the bottom. 8)
pic of that tomorrow...
Text book of Steve's video.
Thank you Steve!

To me it looks like you have copper still in your solution. Did you rinse foils properly before adding them to fresh HCl/Cl?

Looks like your working indoors, I don't see a fume hood.

lala14, next time whan you wash the foils,

start with 3X of water (you might want to do the first water rinse with boiling water to rid of any lead that might be in there)
continue with 2x HCL washs on low/medium heat, these rinses will probably be golden/yellow colord, most likly it's copper, but you should test it anyway.
the thired rinse do in room temp' and leave to sit for 30-60 minuts.
siphon.

then HCL+Cl.


about your current batce, what does the test say?

I would be very careful about putting glass, even good Pyrex directly on the burner. It creates hot spots , thus strains in the glass that could cause the beaker to shatter without warning. Hot AR can make a big mess even nastier.

i'm not sure i undersand what you mean.

a good laboratory pyrex beaker, if heated correctly (slowly) will hold just fine even with direct heat to 100c +-

anyways, i always use a large pickles can with a layer of sand on the bottom to spead the heat evenly to the vessle and limit any mishap that may happend.

good luck

I used to use a sand bath in a skillet for certain things. Very even heat, especially when you pile up the sand around the beaker. It works great but that sand seems to stick to everything and it gets everywhere, even inside the beaker if you're not careful.
