How to make a colloidal silver generator with a current limiting diode

Updated February 21, 2017

People use colloidal silver to prepare household products like disinfectant spray and sanitiser, and personal care items like mouthwash. The usual way to produce colloidal silver is by electrolysis, often employing a current limiting diode to maintain consistent current as the electricity binds the silver colloids to the water. Colloidal silver may be purchased, but you can easily make it at home. You can buy a colloidal silver generator but it is much more cost-effective to make your own.

  1. Arrange the three batteries in a row.

  2. Attach an alligator clip to the negative contact of the first battery. Attach another to the positive contact of the last battery.

  3. Strip about an inch of the plastic off either end of the two small electrical wires.

  4. Wrap the end of one wire around the positive contact of the first battery. Wrap the other end around the negative contact of the second battery.

  5. Wrap the end of the second wire around the positive contact of the second battery. Wrap the other end around the negative contact of the third battery.

  6. Grab the alligator clip that is attached to the negative contact of the first battery. Attach the other clip the current regulating diode.

  7. Attach another alligator clip to the other end of the current regulating diode.

  8. Fill the glass with water, almost to the top.

  9. Attach the silver coins to the free alligator clips. Clip the coin and the clip to the glass so that the coin is partially submerged in the water.

  10. Store the water in a dark place while the electricity binds the silver colloids to the proteins of the water. Allow about 45 minutes of electrolysis per ounce of water.

  11. Tip

    Opinions differ as to the best method of creating colloidal silver. When using this generator to make colloidal silver, research how much time and voltage are recommended for the amount of colloidal silver you wish to make.

    Warning

    While some enthusiasts consider the ingestion of colloidal silver to be healthful, the FDA has issued warnings to various companies marketing it to consumers. If you are considering ingesting colloidal silver, make sure you research the topic thoroughly. Do not ingest colloidal silver if you are allergic to silver.
