Module 1 DIY: Make your own colloidal silver


It is believed that one reason wealthy families throughout history had better health is because they used silver utensils for eating meals. Over time, it’s thought, they ingested silver molecules which helped their bodies fight various bacteria and viruses.

In fact, silver has shown to be effective in fighting bacteria, viruses, algae and fungi. The International Space Station utilizes silver in its water purification, and the World Health Organization uses it in water filters. At one point in history, silver coins were dropped in bottles of milk and water to keep them from growing bacteria, and for many decades it was used by medical professionals as a sort of antibiotic.

For our DIY project, you will be making colloidal silver, a solution of silver microscopic particles suspended in a liquid. In our project, the silver will be suspended in distilled water.

Traditional medical experts tend to discount its effectiveness, but colloidal silver has many fans and believers, and in a worst case scenario, it could become a valuable product for sale or barter. Therefore, it’s important to know how to produce it properly.


  • Large glass jar
  • Distilled water
  • 3 9-volt batteries
  • 1 package 9-volt snap connectors
  • 1 package alligator clips with jumper leads
  • 2 clothespins with springs
  • 2 1-ounce .999 pure silver bars, rounds, or rods
  • Dark glass bottles to store the colloidal silver
  • TDS Meter (Total Dissolved Solids)



  1. Fill Mason jar 2/3 full with distilled water.
  2. Connect the 3 9-volt batteries in series. They will form a pyramid.
  3. Connect the snap connector to the empty positive terminal.
  4. Connect another snap connector to the empty negative terminal.
  5. Connect one alligator clip to the positive wire.
  6. Connect one alligator clip to the negative wire.
  7. Add one silver bar/round/rod to each of the opposite ends of the alligator clip.
  8. Slowly place the silver piece into the distilled water and clip
  9. Place the second silver piece in the distilled water and clip
  • Make sure only the silver is touching the liquid.
  • Don’t let the silver pieces touch each other.

After 10 minutes or so, you’ll notice tiny bubbles coming from the positive anode on the silver piece.

The negative anode will become darkened. Let the system work its magic for 1-3 hours, and check every 30 minutes or so with a TDS meter until there’s a reading of 10-15 PPM (Parts Per Million).

When this level is reached, the solution is done. The freshness of the batteries will determine how quickly this happens.

At this point, the colloidal silver liquid may look clear or have a pale yellow, dark yellow, or even cloudy appearance. Over the course of several days, the PPM level will decrease but then will stabilize. If you wish, the liquid can be filtered through a coffee filter to eliminate any dust or contaminants that may have fallen into the Mason jar.

Once the solution is finished, store it in dark glass jars, such as the amber bottles used for flavoring extracts, or you can buy them online.

TIP: To check for true colloidal silver, shoot a beam of light through the finished solution. A red laser light from a LED flashlight works well. The light will look like a thin line which gradually gets wider as it reaches the other side of the jar. This is called the Tyndall effect. If you see this in your jar of solution, you have true colloidal silver.
