Colloidal Gold Production / Re: 1000mL Purple Failures

Possibly just your tastebuds detecting a residue of chlorine?

Try a different make of distilled water if you can, but make a slightly less concentrated version to begin with; that will avoid wasting too much gold.

Colloidal Gold Production / Re: 1000mL Purple Failures

Late update: I've returned to making 250mL batches successfully using a 3D printed fixture that allows me to adjust the distance between the electrodes. So the metal lid I was using must be the cause of the 1000mL production going bad, but I'll have to give it another go with the fixture instead of the metal lid to verify. For now, I'm wondering why my CG still tastes a little funny, there's a sort of tanginess to it but I have no idea how to describe the taste. I'd let it sit for an hour to let the chlorine gas go away but the taste remains. Perhaps I should try different distilled water.

Since ionic silver is clear, it has to be reduced silver.
It was made with maltodextrin.
Is maltodextrin added when it is hot or after it cools down?
Maltodextrin is added before the run starts.

"is it going to turn back into iodine on it's own?"
Iodides are water soluble, so rinse it out with plain water.

Thanks for that info Kephra. That clears things up a lot.   ;)

Stained my finger with Lugol's, soaked a rag with vinegar and used it like a washcloth on the area. Stain gone after a couple minutes.
You converted the iodine (orange) to iodide (clear).

I did see some of the iodine get onto the rag while doing it. I guess a question would be, "is it going to turn back into iodine on it's own?". If I use it on a stain in fabric and the stain comes back, that would be a problem.

On a different note, I recently used borax as a carpet cleaning agent (with no detergent). Coffee stains (and all others) eliminated quickly. Also soaked the old brown smoke stained blinds (I quit years ago) in borax in the tub (over night) and they came back to their old cream colour. Nice.
