Totally agreed, but so far I haven't been able to convince them of the contrary...
It was ever thus. You cannot make Colloidal Silver without wanting to pass on the concept to others, but when you do, they will immediately start to tell you where you are wrong, or that your product is more likely to cause harm than a commercial antibiotic (!) or that you don't know what you are doing, all without any evidence or knowledge whatsoever.

I have perfected the art of keeping a straight face when I am being spoken to by idiots. It is quite extraordinary how a nurse assumes that her/his qualification (as a nurse) also qualifies them to be an expert in biochemistry or nanoparticle manufacture. I have even been told, by a nurse, that I was wrong when I said that everyone sees the world upside-down, and that the brain performs the adjustment to perceive that "up" is actually "up". Extraordinary.

@ Timothy:

Добро пожаловать на форум CG & colloidal silver.
Все материалы на английском языке. Есть ценная информация о производстве коллоидного золота и коллоидного серебра для тех из нас, кто любит заниматься этим.
Лучшая часть этого - то, что процесс был задокументирован через этот форум. «Как будто у нас есть лучший друг, ведущий нас за руку». Вопрос, на который нужно ответить, это «найти способ» найти его »!

За ваше здоровье!

==========
Welcome to CG & colloidal silver forum.
All material is in English. There is valuable information on the production of colloidal gold and colloidal silver, for those of us that like to pursue that avenue.
Best part of it is that process has been documented throughout this forum. "It is like we are having best friend leading us by the hand". The question one needs to answer is to 'find a way' to acquire it"!

To your health!

Hello to everyone. A very useful forum. Thanks for the shared information. Product in the picture:
450 ml DW (PH 7.1)
Electrolyte: 50 ml clear ionic silver (TDS measured 18 ppm)
Power: 15 DCV
Current: 0.5 mA (500 microA)
No heating: 22 C room temperature.
Electrode: 15 cm silver bar.
The anode is in the water. The cathode was immersed in 1 cm.
Mixer: None
Reducer: None
Duration: 180 minutes
No metallic taste. It's not burning like ionic silver.
No residue.
TDS: 14 ppm.
What did I do now?
Is this a colloidal silver?
Or something else?

Since you did not follow the techniques here, it is impossible to say what you made.
Also a TDS meter is useless in determining the ppm of colloidal silver.

Thanks wgpeters for your reply. I'm practicing your techniques. I started to make 1 liter once. I added 20 drops of sodium carbonate as the electrolyte. 10 DCW, 3 mA. I did it for 100 minutes at room temperature. I cleaned the electrodes. The same color occurred. Even though I don't use a reductant.
There's something I don't understand.

Check your water quality.
Also, fluorescent lighting and sunlight will reduce silver.

Even though I don't use a reductant.

The reducer has at least mild stabilizing properties that keeps the colloids from clumping together into larger useless particles.

If I don't add the reducer it changes on me as well but keeps getting darker and darker until it looks kind of brownish. This can take from days to weeks for me.

As most people here I have become used to evaluate the process, presence of AgNP, particle size and concentration based on colloid color. As soon as the colloid shows a strong yellow color we know that we have about 20-25 ppm concentration (cross-referencing mA and time), caused by the Plasmon effect.
I have reduced and capped nano silver using many different protocols, some with application of heat, some at or slightly above room temperature.
When I do a citrate reduction/capping, that has to be done at 70-80°C, I generally heat up the water, add the sodium carbonate, glucose (to ensure full reduction) and citrate, and then insert the silver electrode. I noted that when I wait a minute or ten, the water will color bright yellow even if no silver is present. As the Maillard reaction should not take place at such low temperatures, I was puzzled, but now I learned that sodium carbonate will drastically lower the temperatures for the Maillard reaction to happen.
So my question is: When heat reducing nano silver, how can I be sure that it is indeed reducing, or am I just looking at a yellow solution because of the Maillard reaction?
Also: If it is a combination of the Maillard reaction and Plasmon effect, how can I evaluate yellow/amber colors with respect to concentration? Any thoughts?

I have tested this with sodium carbonate and corn syrup (glucose+maltose), heated to 200F and no color change occurs.  If you are getting color change its not from the Maillard reaction.  The Maillard reaction occurs between amino acids and reducing sugars.  So if no amino acids are present, its not the Maillard reaction.

Heat reduction uses no other reducing agents.

OK, thanks, I will investigate further. The color was too strong to be caused by just contamination or silver residue on the beaker.

Were the A and B bottles in the initial post created using Sodium Carbonate during creation? I did not use any in my current first attempts. I added some golden syrup but it's still hazy clear colour. I have ordered some Sodium Carbonate to add to it and I am hoping it should then reduce to the yellow colour. If I were to microwave what I have, would that reduce it?

Also, I had a glass I was dumping bits of water into from cleaning my bottles and I think I may have dumped other stuff in there. I put some of my silver into a glass and added some borax to see if it would raise the PH and go yellow... nothing happened so I got annoyed and dumped it into the waste water glass and low and behold it turned yellow like the pee you have after a while after having an energy drink... So no clue what was in there or what conditions were but I know (I think) that what I have will work if I can just get the ph sorted out even though I did not use any sodium carbonate during it's electrical creation?

Follow the instructions precisely.

We have been testing these methods for many years. If you follow the instructions, you will get the correct results and have very few failures. Use small volumes of Distilled Water to begin with.

Thanks. I think I am getting decent results as I progress and tweak things more in line with existing articles here. Initially I started out with an eBay simple 2 lead set up. As time goes on, I upgrade my gear and knowledge.

Is there specifically a guide on making higher ppm concentrated batches? I like this 20ppm deal but I think it might be nice to make a more potent ppm one for storage and dilution, or to make taking larger loading doses while sick more convenient than consuming larger quantities of 20ppm perhaps. I have read that 20ppm is pretty much the maximum without special steps or capping or what ever but I don't recall seeing a guide specifically about making high ppm strengths. Do you know of an article which covers this?
