Introduction: Colloidal Silver Generator

This is my first instructable and I hope that it can help you build your own. This picture shows the completed generator working on the first batch, using distilled water measuring 0ppm. Do not use any other type of water.

I first started experimenting with Colloidal Silver after a friend suggested I soak my dry, itchy, flaky skin and cracked hand which I have had chronic problems with for over a year and nothing worked for long to help it. After two 5-10 minute soaks over 4 days, It was back to normal. I was hooked.

I had success starting with a simple 3-9 volt battery set up, 16 gauge fine silver wire and 1 oz fine silver bars. I then added a magnetic stirrer but was not satisfied, so I pulled ideas from several U-Tube video's (Zero Labs and Health Wyze: (, and this is the result. My apologies for not taking pics as I built it, just got too involved into putting it together and concentrated on that rather than pics of the process. I hope my photos of the finished project and explanations will be enough for you to make one if you like this design.

Step 1: Parts List and Tools

Here is the parts list:

For the magnetic stirrer:

1-Hammond 1591ESBK ABS Project Box Black, 7.5 x 4.3 x 2.2 Inch, from Amazon, $7.31

1-Generic Low Voltage Dc 1.8v 3v 5v 6v 12v 2a Motor Speed Controller Pwm from Amazon, $3.57

1-4 inch computer fan

1-12 volt power supply

1-1 1/4 inch 1 inch PVC

2-small rare earth magnets

5-pieces of velcro, approximately 1” square or rectangular to hold the fan in the box.

2pcs 1 inch B25 magnetic stirrer bar stir mixer bars PTFE lab spin spinner from Ebay, $1.59

Shoe Goo glue

For clip connectors to silver wire and bars:

1/4 inch electric guitar plug and 1/4 inch and 1/4-Inch Electric Guitar Input Jack, Cheap on-line.

1-DPDT switch from Home depot for reversing polarity.

16-18 guage stranded copper automotive wire

2-Alligator clips

6 inches of fine (99.9%pure)16 gauge silver wire and two 1 ounce silver bars.

Tools needed are a drill and various bits, good soldering iron, solder and flux. Helping hands jig comes in handy for holding the wire and parts when soldering.

Step 2: Putting It Together

I first attached the velcro to the bottom of the fan and pressed in place in the project box. You can use any kind of box so long as it supports the water, jar and silver placed on top. I then soldered the ends of the motor wires to add rigidity to them and attached them to the motor speed controller which I had attached in front of the box as you can see in the top picture (Blue knob on front). Controlling the speed of the stirring is important. I found that a slow speed works best. The DPDT switch is just to the right of this which I used to reverse the polarity to the silver bars every 30 to 60 minutes to keep them evenly used. The bars tend to get black oxidization on them and this keeps both even. You need to clean them after about two hours.

The second picture (top view) shows the DPDT switch on the left used to run power to the silver bars and reverse the polarity. Just to the right of that is the motor speed controller to slow the stirring. On the right side is the fan attached with velcro on the bottom with the PVC piece glued to the top and magnets glued into notches cut into the top. It is a bit tricky to measure and cut the right size PVC and remember that the weight of the water may lower the cover some. You just have to cut more than one piece and check that before you glue it in place.

It was helpful to center and spin the fan by hand to check for stability and good center before it sets.

Note the fan power wire going into the hole in the back from the 12 volt power supply to the speed controller then to the fan. The 1/4 inch plug and jack are for attaching the leads that attach to the silver wire and bars which I like because it can be unplugged and put away. I plan to do the same for the power from the 30 volt and 12 volt power supplies, but will use a smaller mono headphone jack for the 12 volt.

Step 3: View of Power Supply Clips Attached to the Silver Wire and Bars.

Here you see the leads with the alligator clips attached to the silver wire. I used fine silver wire attached to the silver bars by drilling a very small hole in the top of each bar. This way the bars could be fully immersed in the distilled water for more efficient electrolysis of the silver to the water. The 30 volt power supply was recommended by Health Wyze, but they stressed that with any power supply, the risk of fire or accidents is important to consider, so you may want to use batteries. They used copper wire to attach to the bars and because of this only immersed the bars half way. I thought this was not efficient so I used silver wire and fully immerse the bars. This project is under your full control and at your own risk. Here is that link for Health Wyze again:

Step 4: Using Your Generator

Fill the glass jar with distilled water to just cover the silver bars. Distilled water has very low conductivity so the process can take a very long time. Some people use up to 10 ounces of colloidal silver from a previous batch to increase this, but I found that heating the water works very well for this. Take the bars out then heat the water in the jar in a microwave for about 4 minutes. You are aiming at 150 to 160 degrees. Put the bars back in the water and attach the alligator clips to the wires and turn on your generator. I had them both on a surge protector and checked the voltage at the clips. I also found that a slow speed on the stirrer works best. Cover the jar with a plastic lid and change the polarity every 30 to 60 minutes. I did every 60 for the first two hours and did not use any colloidal silver water as a primer. I learned that this tends to cause more oxidation (yellowing) than I preferred. The darker yellow the end product is, the lower the quality.

Clean the bars with distilled water and a copper scouring pad every two hours or so and filter the solution through unbleached coffee filters, (I use one, some people use more). Wash every thing with distilled water only and clean paper towels, no soap. I use copper coated scrubbing pads.

Check the PPM after each hour or so and remember that the number goes down a bit after it sits for a while with the generator turned off as well as when you filter the solution through coffee filters.

I had a great, fairly clear solution after about 3-4 hours. You can also use a red laser light to check for Tyndall effect and actually see the sparkling silver particles. Store in dark bottles in a dark place and check the internet for more information. It has also helped my allergies better that any meds or nasal sprays I have used.
