Note: These (except of 3.) are general processes used to create soles, not necessarily colloids of silver.

1. Dissolution
   Chemically created colloidal dispersions using a solvent. Solvent examples are gelatin, gum arabic, agar-agar, dextrins, starch, soap, bentonite in water. The process usually involves soaking and heating.
   
   
2. Mechanical (Siddha Medicine)
   This production is done using a "colloid Mill" this method is one of the old methods used and is no longer used with silver because the particle size is too large.
   Siddha Doctors in India still sometimes use to cure stubborn bladder infections with ground silver, using up to 10g over weeks, in order to reach satisfactory results ! For comparison: usually it takes a few tablespoons of "Rajatam" over a few days maximum, to get rid of even stubborn bladder infections safely.
   
   
3. Electrical (= RAJATAM!)
   The electro-colloidal process was first done by striking an electric arc under water, though first done by Guyton-Morveau in 1809 with gold. The use of metallic wires precipitated into water using the Bredig apparatus was coined the "Bredig method". Our discussion here with focus on electrical precipitation created in recent years for the production of isolated colloidal ionic metals. Of course, in order to gain this, only DISTILLED or reverse osmosis (R/O) water can be used for the electric arc, i.e. placing two ultra-pure silver- (or other metals) wires into this pure water under a certain current. (See more below)
   
   
4. Oxidation-reduction
   This process is the formation of sols by the use of reducing agents. This process has been used extensively to create gold sols / gold hydrosols. but not as often with silver sols. This process was used before colloids as a state of matter were known. Heat and reducing agents such as phosphorus were most commonly used. The preparation process may also involve hydrogen peroxide, formaldehyde, hydrazine and tannin which were used to create the hydrosol. These hydrosols were used for coloring fabric and glass and were initially also used in hospital tests on spinal fluid.
   
   
5. Double decomposition
   This production method uses double decomposition reactions to create sols. They fall into basically the following groups: oxide, sols, sulfide sols and salt sols. Hydrolysis focuses on pH as a focus and involves complicated chemical reactions by creating a base causing hydrolysis that creates a salt that can be either acid or alkaline. For example adding a small amount of a solution of a salt to boiling water. Another example is hydrous oxide is treated with with a small amount of acid or base or of a solution of a salt which is acidic or alkaline and is then dispersed. It is a complicated chemical process normally used to create salts & compounds.
   
   
6. Simple precipitation
   This process is a simple formula. When a solution of substance (A) in liquid (B) is poured into liquid (C) a sol generally arises, if (A) is insoluble in (C) and provided (B) and (C) are capable of being mixed in all proportions. Example: Sulphur dissolves in hydrazine hydrate forming a deep red stable solution, when poured into water the result is a clear bright yellow dispersion that is sensitive to carbon dioxide.

Types of Silver Preparations

• Electro-colloidal: a specific current is ran for a certain time through two wires of silver, which are placed into a jar of DISTILLED or R/O Water. This arching actually is nothing else than a set up for metal-plating – electrolysis process. By the electrical charge, tiny silver particles will break off the purest silver wires and, held by a positive charge, will stay in suspension for many months, due to certain factors of the performance of the process. No other ingredients than purest silver and distilled water are involved !! Our electro-colloidal ionic Silver product is produced with a low-voltage Coll.Metal AC–generator from USA.
  
  
• Mild silver Protein: (MSP) This process chemically infuses or binds the silver to a protein. The parts per million vary from 20 PPM to 200 PPM and concentrated as high as 5000 PPM.
  
  
• Powdered Silver: This production method was developed in Russia. It could be described as both a thermal and electrical process. A very high voltage is used to disintegrate the silver into powder (better ash), also known as water soluble silver.
  
  
• Ground Silver: This process is just like it sounds, Silver is pulverized and ground into a fine powder. This process became obsolete in the 1920's, because it did not create a small enough silver particle.
  
  
• Silver salts: These are silver compounds, that cannot truly be considered colloidal silver. They are produced chemically or electrochemically. They may posses a positive charge but are usually a silver compound. Below are some examples of these silver compounds, and their historical or present uses.
  
  
• Silver Sulfadiazine: Bactericidal and anti fungal uses, particularly used in burn cases.
  
  
• Silver Nitrate: Disinfectant used in podiatry, and placed in infants eyes at birth to prevent blindness. Ulcer treatment.
  
  
• Silver Iodine: Disinfectant
  
  
• Silver chloride: Disinfectant
  
  
• Silver Lactate: Astringent & antiseptic.
  
  
• Silver oxide: Previously used for chorea & epilepsy
  
  
• Silver picrate: Uses, moniliasis & trichomoniasis.
  
  
• Silver Arsphenamine: used also for intravenous application, causing Argyria at a single dose of about 1g!
  
  
  
  Comparison: to digest 1g of Silver with "RAJATAM", one would have to swallow 100 litres of the product at one time!!
