A colloidal solution is nothing more than a substance(usually microscopic) that is dispersed throughout another substance.

Not to be confused by the disinformation that ionic cannot be colloidal as many purveyors seem to allude to when putting forth such claims as; only particle silver qualifies for the so called true Colloidal Silver etc etc :)

As for the ionic test, I'd say your best bet would be the table salt test. As both ionic and particle or metallic solutions can exhibit color. Albeit, the particle variant will most often yield a brown tint whereas the ionic variants will almost always follow a straw/gold color.

On the topic of concentrations, I wouldn't call 10ppm inferior as much as it is simply weaker. Which would likely mean that may need to take larger doses in order to match another product or regiment.

Having said all that. I'd exercise caution If your solution is truly rated at 10ppm and is exhibiting color as this means that there is most likely something else going on. ie, even in cases where particle silver is concerned(w/much larger particles than ions), the hue at 10ppm would likely be negligible. Whereas a naked ionic solution should not exhibit any color at all at 10ppm.

Hope this helps.

The true facts about colloidal versus ionic silver are NOT what is being put forth by some here who evidently think they know what they are talking about, but don't.

Here is the real information:

OK, first of all your question about the color: Yellowish can be indicative of larger particles or possible contamination too. Colloidal Silver tends to be more amber or tea-colored.

Now regarding the true facts about colloidal versus ionic silver:

Ionic silver is not the same as metallic silver nanoparticles . For example, metallic silver is not water soluble (does not dissolve in water) but ionic silver is water soluble (it does dissolve in water). Technically speaking, a silver ion is an atom of silver that is missing one electron. It is the outermost electrons of an atom that determine the physical properties of matter. Take away one electron from a silver atom and you get a silver ion which is water soluble. In its ionic form, silver is highly reactive with other elements which means it will readily combine to form compounds. Ingestion of highly concentrated forms of ionic silver (having a silver concentration of 100 ppm and above) could potentially cause a condition called argyria, a permanent discoloration of the skin.

Because a true silver colloid consists of silver nanoparticles, not ions. Inside the human body ionic silver quickly combines with chloride to form an insoluble compound called silver chloride which is far less reactive than metallic silver nanoparticles. In fact, ionic silver cannot survive inside the human body. In the digestive tract hydrochloric acid supplies the chloride ions that cause ionic silver to quickly form silver chloride. If some ionic silver were ever able to get into the bloodstream it would encounter a large supply of chloride ions owing to the fact that blood serum is rich in sodium and potassium chloride, again quickly forming silver chloride. Only silver nanoparticles can survive inside the body.

I also refer you to this collaboration on colloidal and ionic silver by a panel of true Colloidal Silver experts:

And btw, PPM is not the most important measurement when it comes to silver solutions. Particle SIZE on the other hand, is of utmost importance. The smaller the particle size the greater the coverage area per given PPM. Almost all silver solutions made at home as well as a large portion of the commercial mostly ionic silver solutions have particle sizes which are much, much larger than the very best true colloidal solutions.

Little difference between ionic and Colloidal Silver ? Try this: get one of the superior true colloidal silver products (Purest Colloids Mesosilver or Utopia-Silver 's Advanced Colloidal Silver) and take four sliced of bread out and mist them first with water and then mist one with homemade silver, one with a commercial ionic silver such as the one you have, one with a true colloidal silver solution and leave one alone other than the misting with water. Now, leave them out and see which ones develop mold most quickly. You will find that the water only bread becomes moldy in just a couple of days or so, followed shortly thereafter by the homemade silver and then the commercial ionic silver. WEEKS later the ones misted with true colloidal silver will not have any mold. You can do the same thing with glasses of milk and see which ones become soured and moldy first.

This has already been done in the past by a CZ member insofar as the bread slices and the results were exactly as I just described.

And to those self-appointed authorities here, I invite you to go down to Utopia, Texas and go visit Ben Taylor and his facilities and see how his true colloidal silver is made. It bears no resemblance to the ionic electrolysis method used in home generators or the vast majority of commercial ionic silver. If such production methods did not produce truly superior silver solutions, then one must ask why the two producers of true colloidal silver have set-ups that cost them upwards of half a million dollars when they could just be making ordinary silver and hyping it like most of the other manufacturers do?

When you make your own you know what is in it.

I stopped last night. I haven't had any form of crap like this in my chest and throat for as long as I can remember. My voice has been gone for 5 days(which, so happens, started the morning after my first CS/Nebulizer treatment. Still coughing like a champ, in pain, and with a little blood in my saliva. Other than the reddish tint to my saliva, I am not coughing any colored spittle.

I have a dr's appointment in 2 hours.

Day 10, voice is still gone(to an extent) Haven't used nebulizer for about a week. It's the craziest thing.
