Types of Colloidal Silver (CS)
There are four main types of CS. Ionic, stabilised (capped), sugar-reduced and heat-reduced. Recipes and production methods will follow soon. All types fall into one of these categories.
Ionic (Colloidal Silver Oxide) is just Silver Oxide dissolved in water; the makers of this type of IS normally make it by electrolysis, the same as other forms of CS; IS is normally the type sold on most commercial websites. It is colourless, tastes very metallic, and MAY in VERY LARGE quantities, produce Argyria (the grey/blue discolouration of the skin). It works very well, and used to be the only version available. It is best for topical use (on the skin), where it not only stops infection but promotes rapid healing. I remember watching entranced as a small but deep cut healed over during the course of a working day as I kept it wet with IS, constantly wetting it with a spray bottle. Although best used externally, it can be consumed and I have done so, before I learned to make the reduced versions. I still use it for skin infections, spots and abrasions. It can be used for disinfecting hard surfaces, but may stain some substrates. It is made using distilled water at less than 30 degrees C. Cold distilled water is fine.
Stabilised or capped CS is the product for which we have to thank Kephra the most. When stabilised with cinnamon or gelatine, CS is easy to make, can be made very concentrated, is excellent when I take it internally, and the cinnamon probably gives a synergistic effect. It is golden-yellow to light clear brown in colour, tastes vaguely of cinnamon but not much else. No version of CS stings in the eyes if properly made. The idea is that the cinnamon partly protects the CS as it proceeds through the stomach, and the cinnamon is then digested, releasing the CS to do it’s work. In theory, it should be much less effective externally, but I have personally seen it work reasonably well on skin infections and abrasions, although I would prefer to use IS or sugar-reduced CS externally. I would also probably prefer to use sugar-reduced CS for purifying water, but as one is drinking it anyway, cinnamon-stabilised CS will work. Best used for internal illnesses, can be used externally if you have nothing else, but not (in theory) very useful for sterilising hard surfaces. It is magical to watch the distilled water turn golden-yellow as the process continues; if you stir the DW more slowly than normal, you can even watch wisps of yellow CS stream off the Silver anode. This is the best form of CS for internal consumption, and is the easiest to make. Normally made using hot DW, it can be made cold if you stir the water well.
Sugar-reduced CS is the generic all-purpose product. One simply makes IS by electrolysis and adds a drop of golden syrup (UK) or Karo (USA) to reduce the IS to CS. Alternatives are glucose (dextrose) or fructose (laevulose). Sucrose (table sugar) will NOT work. The silver oxide is reduced to silver particles, and the plasmon resonance of the Silver means that you watch the liquid turn golden-yellow almost immediately. I add the sugar shortly after starting, but it is better to add it at the end of the process, as then one does not electrolyse the sugar. It is normally made hot, around 80+ degrees C, or you can boil it in a microwave at the end of the process. I use it for all uses, internally and externally. It should be bright yellow when finished, around 15-20 ppm, and tasteless.
Heat-reduced CS was the first improvement over the basic IS. It only differs from IS in that it is made with the distilled water kept hot (over 80 degrees C), or it can be made cold (as IS) and then boiled in a microwave until no further colour change takes place. It varies in colour with the strength of the product, from a faint clear yellow to deep yellow, can be made up to 20 ppm and can be injected if you have the skill to do that (when it has cooled!) I have not used it intravenously myself, but would have no hesitation to do so if I was suffering from a life-threatening bacterial illness (DISCLAIMER – I am not prescribing or recommending this use; I have no medical qualifications). Normally, I take it internally but is also perfect for external use. It is quite normal (but theoretically undesirable) for heat-reduced CS to actually be a mixture of CS and IS in varying proportions, but the more CS and less IS, the better. Only two commercial UK companies make this for sale, and both work well. I make the same thing far more cheaply, and so can you – recipes to follow soon. It tastes almost of nothing, sometimes with a metallic taste, depending on the amount of IS remaining in the product. It is very delicate, and can oxidise back to IS under some circumstances, when it goes a muddy grey colour (still OK for external use, don’t throw it away).
All versions should be stored in glass or clean PET plastic bottles. It does not need refrigeration, and must not be frozen; a cool place is all that is necessary. IS is better stored in the dark or in a dimly-lit place, the rest can be left in sunlight. Brown bottles are only suggested for IS and heat-reduced CS, but well-made heat-reduced CS can be stored in clear glass. It is self-sterilising. Keep opened bottles from contamination, or you may find that your IS reduces to the equivalent of sugar-reduced CS “apparently spontaneously”.
