How to Make Colloidal Silver at Home

There are probably some methods on the net on how to make colloidal silver at home. One of the readers of the blog sent me his own, which I found particularly simple and well explained. So here it is …

The properties of silver are considerable (antibiotic, antifungal …). It is a metal with powerful medical properties. It has been used since the early days of civilization to heal the wounded and the sick. Its use can treat men, but also plants and animals …

It is in its colloidal form that silver is the most effective. So here is a complete tutorial to make it yourself at home with easily available materials.

Colloidal silver is a solution formed by millions of silver microparticles suspended in deionized water. In this form, the healing power of silver is multiplied.

The list of treatable diseases is long: caries, diarrhea, scabies, hepatitis C, pertussis, herpes, urinary infections, warts …

It is obtained using an electrolysis process :
Two silver electrodes are immersed in Pure water and an electric current flows between the two electrodes, thereby generating silver ions in the solution.

Colloidal silver can therefore become a central part of preparation in the context of survivalist preparation. Indeed, in the case of a break in normality, this solution can compensate for the lack of medicines and in particular the lack of antibiotics. This solution also makes it possible to purify water with great efficiency.

We have developed this tutorial based on our own experience but also on the experience gained from specialists. We tried to be as clear and concise as possible.

1. List of equipment

1. Two  electrodes

How to Make Colloidal Silver at HomeFor a high quality solution, the electrodes must be 99.99% pure.

Instead, rely on sites that offer a material certificate (avoid Amazon and non-EU sites).

For example, these are from the Swiss website, but you can also find them on

2. Distilled water

How to Make Colloidal Silver at HomeYou can buy it in pharmacy approximately between $5 and $8  per liter. The quality of the water is very important to obtain a quality solution.

The ideal is to take a glass container. We have chosen for example a jar of 500g jam with screw cap.

4. Electrical Transformer

How to Make Colloidal Silver at HomeAn electronic device charger is perfect. In our case we used an old camera charger. It is recommended to use a device with a voltage of between 5 and 24V. This makes 13.5V output (information visible on the sticker).

5. Alligator clipsHow to Make Colloidal Silver at Home

These are small electronic clamps.

They will be used to bind the transformer to the electrodes.
Cost on Amazon: $3

6. A conductimeter

How to Make Colloidal Silver at HomeDetermines the total amount of mobile charged ions, including minerals, salts, metals, cations or anions dissolved in water.

It will evaluate the concentration of microparticles of silver in water in PPM (part per million).

Cost on Amazon: $12

7. Electrician’s Scotch

How to Make Colloidal Silver at Home
Can be found in all traditional DIY shops or on Ebay for $1 per roll. The interest of this scotch is that it is non-conductive (easier to find and more practical to use than a cork separator).

8. Amber glass bottle

It will make it possible to store and keep the solution in the best conditions. Colloidal silver of good quality well packaged can be kept for several years

Cost on Amazon: $4

=> The objective is to produce 500ml of solution loaded at 10 PPM.
10PPM is largely sufficient, a higher concentration is not useful.

2. Preparation:

– Strip the end of the cable and crimp the crocodile clamps.

– Drill the cover of the electrode diameter + margin 0.4mm (for example: drill Ø2.4mm for an electrode diameter of Ø2mm).

– Wrap the scotch around the electrodes.

It will make it possible to position the electrode in the cover and create the protective layer to avoid short circuits. Observe a distance between the tip of the electrode and the bottom of the glass about 1 to 2 cm.

– Glue two strips of insulating scotch tape to the lid.
They will serve as a support for crocodile clips and avoid short circuits.

– Provide a stopwatch for time calculation.
– Provide a plastic tray that will allow the solution to be stirred.

Fill the jar with ¾ distilled water.

3. Information required for production

Measurement of the concentration of silver (PPM).
The concentration of the silver nanoparticles in the purified water is measured in PPM.
The PPM (part per million) refers to the number of parts of silver for each million parts of water. 10PPM = 10 parts per million, ie 10 parts silver for one million parts of water.

This concentration is measured using the conductivity meter.
There is a near scientific consensus that no disease requires a concentration greater than 20 ppm. A concentration of 10PPM is large enough to cure most ailments.

Before electrolysis, the conductimeter indicates 0 PPM. The distilled water is completely pure.

Color as a quality indicator.

Color is a simple indicator to gauge the quality of the product you have made.
The liquid must be totally colorless. A pale yellow or even orange tint reflects too high particle sizes.

High particle sizes reduce the curative effect of the product but are not fundamentally harmful to health.They will in any case be evacuated naturally by the body in the urine.

If you have any doubts, use the precautionary principle and discard the product.

4. Production

Once the installation is in place, connect the transformer plug.

At first nothing should happen. Then after a few minutes, small bubbles should form at the end of the electrodes. To distribute the microparticles correctly in water, it is necessary to perform three operations every 15 minutes:      – Stir the solution with a plastic tray.      – Wipe the electrodes with a coffee filter.      – Invert the phases (from + to – and, from – to +) Attention, production is exponential! The higher the concentration of particles, the greater the conductivity. Do regular checks.

The production should last between 80 and 120 minutes with the aim of reaching between 8 and 12PPM.

5. Storage and storage

Pour the obtained solution into your amber glass bottle.
Colloidal silver is very sensitive to light. Keep your bottle in a dry, cool and shady place (no refrigerator needed).
A quality colloidal Silver can be retained for several years.
If colors change over time, be careful and discard the solution.


You are now able to produce and store your own colloidal Silver.

Colloidal silver can be used in war medicine or to compensate for a sudden break in the supply of medicines and antibiotics. The acquisition of manufacturing know-how and the storage of equipment can therefore be considered as an important part of the preparation.

In the case of a generalized collapse, the liquid will have a significant value and can easily be minted. Remember “health is worth all the gold in the world!”.
