Your gold pictures look to be about 5 o 10 ppm. Thats nice gold, just not very strong.
You silver pictures look turbid. Thats not a good thing, but it might be just the way it was photographed.
I'm a gold colloid drink 1000 grams per day!
I for month cured arrhythmia, angina, atherosclerosis, haemorrhoids and prostatitis. Wife cured arthritis.
So a liter at 10 ppm is 10 milligrams of gold. Thats about the dosage most of us take I think. It is what I do, only my gold is much stronger, so I only need a cup/250ml of it.
Some people have been using the high voltage underwater method for years here in the US. I do not promote it because:
A. Someone unskilled in working with high voltage will kill themselves.
B. It doesn't make very high ppm gold.
C. The chlorides that are left with the electrolytic and chemical methods are not harmful so don't need to be removed.
D. Gaseous chlorine boils off during the process.
