[OMG]

You are using the HCl + Clorox method?
If so, I've noticed a lot of people seem to be too anxious and don't let the chlorine finish coming off before they add the SMB. Use only enough clorox to get the job done. Once the gold is dissolved, leave it for a day or so before adding SMB.

Some people heat the mixture a little bit to help drive off the excess chlorine before they add SMB.

When you added it to the solution did it produce a very pungent odor that takes away your breath?

Do you have stannous to test for the presence of gold?

no where do u get that and what is it

 

[lazersteve]

Stannous Chloride is simply metallic tin dissolved in hot HCl.

Some guys are making it with lead free plumbers solder that is 95% tin and 5% antimony.

Put a few inches of the solder in 30 mL HCl and heat until it fizzes. Stop heating and let cool and clear. Put a small piece of tin in the beaker so the solution won't lose it's kick for several weeks.

Alternately you can buy pure tin powder from my website.
