Introduction: How to Make COLLOIDAL SILVER (Easy)

Colloidal Silver is the most potent disinfectant and antiseptic, and on-contact killer of viruses, bacteria, fungi and all kinds of germs. My guess is, if you want to make it, you probably know what is does, and how it has been used for the last 3,000 years. Since you can make it yourself and you need no prescription, you will not see it on TV -- ever!
Items you need:
2 ft. common electric wire  (any laying around in the house)
4 small alligator clamps    ( $6 for 4 at the hardware store)
    A bit of electric tape.
3    9V  batteries  ( about $ 10)
Distilled water  $0.99
Saline  (eyewash drops)  $2-3.00
1 ft silver wire, 999.99  pure . $10-25.00, depending on gauge, a thin one will do fine.
A glass (for the electrolysis) no plastic or metal containers

Instructions in the video.
You don't  need a box for the apparatus or soldering anything. twist the wires and cover with electric tape. Just connect your batteries in series to get 27 Volt.
  When you are done, clean the oxidized wire with a rough cloth or soda, and store all the pieces in a zip-lock bag until next time.
Store colloidal silver in glass, away from light.

What am I doing wrong. After only 2 hours there is an ugly grey cloudy look with black sediment in the bottom of the jar. I have tried it twice and can't get it to look like it is supposed to look like. Does anyone relate or know what could be wrong?

BillB250 (author)TimothyB1212017-05-23

The grey cloudy look is all the silver that is in the water. You need to dilute the crap out of the original batch that you make. Almost impossible to get a low enough TDS of silver on the first go. Buy a total dissolved solids meter for 100 bucks or so. Also, gonna need to buy TDS solution to keep the meter in calibration. That isn't too expensive. 150 ppm solution should do the trick.

TimothyB121 (author)BillB2502017-05-24

BillB250... While I appreciate your attempt to help, I have since done some research and find out that what you suggest is not acceptable. My product was cloudy grey because the particles were too large and too many. .I want a clear liquid of low ppm (10-15) of very small particles. 150 ppm is way too high Diluting is NOT the answer. And an adequate TDS .meter doesn't cost no $100 !
When particles are small enough the resulting liquid will be clear. That can be achieved by controlling the current. I put a potentiometer and a multimeter in series with 3 9v batteries. I can control the current so that it is no greater than 1 milliamp. The result is beautiful!!!

BillB250 (author)2017-05-23

So, if you're going to do this, it's best to remember that the content
of silver in the water shouldn't be too high. I'm not sure what the
most effective level is, but 30 parts per million (ppm) seems to do the
trick. What you need to measure this is called a TDS (total dissolved
meter. They're not super cheap, but it will keep you from turning your
skin blue with too high a silver content. Anyways, measure the TDS of
the water before you add silver and again after you add the silver,
subtract the first reading from the second. Then lets say you have 2
cups of colloidal silver at 90 ppm (original tds reading minus added
silver tds reading). Then all you have to do is do a little math and
adding 4 more cups of water will get you to 6 cups at 30 ppm of silver

If you make this as described above you deserve everything you get.
They're making silver chloride. and possibly some CS but the size is too big for medical grade.
Here is an annotated video with ALL the mistakes made explained and corrected.

Mike-88 (author)2013-09-28

I just made my own colloidal silver for the first time. I think I have a problem though, I knocked the wire rod when I was removing it and the seaweed like particles all fell off into the solution. Will it be safe to consume with the particles in? Should I throw it away and start again?

Chuck SmithfixS (author)Mike-882014-12-11

You are using wire instead of rod. The substance is silver oxide. Throw it out and start over. BTW, you are making Ionic Silver, not a Colloid. Scroll up to my earlier comments.

He said he was using rod!

chuck.smith.1238292 (author)2014-10-08

You should do more than just watch a fer videos on YouTube before putting stuff out. Please read this and learn something. Lives may depend on it. I am always available to talk, and teach. Please take article down the inaccuracies hurt credibility of all you do. On the left is a 20ppm Colloidal Silver. On the right a 20ppm Ionic Silver.

Colloidal Silver Truth! Avoid the Ripp-Offs!

So how do I make Colloid silver & not the Ionic one?

Colloidal Silver Truth! Avoid the Ripp-Offs!

this link says nothing about making colloidal silver. It's just posting a bunch of ads from different people!

Thank you Chuck. I am sure there are ways to produce better forms of colloidal silver with expensive equipment ( like with laser ablation), but this is an easy and cheap way to do it at home, for emergencies. I am not selling anything, People who want to buy, can do their due diligence.

"this way" does not make a Colloid. It makes Ionic. Do not drink Ionic Silver it only becomes silver chloride on exposure to the chlorides in the human body.

Do not drink what you are making. All you will be doing is putting Silver Chloride in your body. Worthless for health. What you are making is NOT A COLLOID. My best to you. Touch base if you want to talk,

How do I mkae the good silver?

tony54 (author)2014-11-09

Here are several FREE booklets from Bob Beck for making CS, blood electrification, ETC so you can learn for yourself. I have found heating the distilled water by almost boiling it helps. If you boil it , that will help remove some chemicals and it lowers the resistance of the water, making a higher concentration of CS without adding anything. I pour the water and add the silver electrodes when it as as hot as possible, setting it on a oven mit to insulate it from the table to keep it hotter longer and keep a over mit around the glass too. Also, keep it out of the light when making it and when storing it. A colored glass is best like a beer or wine type glass bottle or wrap it in a paper bag like I do.

I've found 16 volts from a power supply for 15 minutes them reverse the electrodes and clean them each time with a green scratch pad for doing dishes is needed. It makes a higher concentration with the higher temperature water. Just be careful not to burn yourself. You can put a small light bulb in the circuit in case the electrodes accidentally short together. I use a small length of wood with aligator clips to hold the silver coins in place WITHOUT allowing the water to touch them. The water should touch ONLY THE SILVER. And use a glass container since plastic leaches chemicals into the water. That is why plastic tastes funny I think.

Thanks Tony, good info.

RiteshS4 (author)tony542015-06-24

hi , tony, which bulb u inserted ? how much volt? watt? and ma? ... i m not finding that bulb which bob listed in his protocol... can u tell me which replacement should be taken ?.... thanks.. :)

Chuck SmithfixS (author)tony542014-12-11

Beck did not know the difference between a Colloid and Ionic Silvers. I give hin no credance because of that.

MarkF74 (author)2016-10-16

Stop spamming this blog with your advertisement. There are plenty of good plans for making your own colloidal silver generator online, including the one above.

Red.Dwarf (author)2016-09-24

Before you consider using this internally, do yourself a favour and leave the saline out! It will take longer as a result because the water resistance is higher. Using some from a previous batch would help speed up the process.

Then you should get a current regulating diode of 1mA. This needs to be hooked into the positive lead after the batteries and before the electrode. This will ensure that the current does not rise when the resistance lowers as more silver ions enter the water. This is very important! This will keep the quality high and prevent large particles being formed which are harmful. If you look up Papa Smurf the blue man you will see that he used salt in the water and he did not restrict the current flow and he ended up blue/grey as a result.

Having something to stir it would also be beneficial. You could make a magnetic stirrer from an old PC fan. See youtube for instructions on building one. They can be made fairly cheaply using a lunch box and a fan, two small rare earth magnets/Neodymium which are glued to the fan, preferably a variable resistor and a 12 volt power supply. A stir bar is needed which you put in the bottom of the glass flask. This helps prevent agglomeration of the silver.

This does complicate it but it pays to do it safely rather than having regrets because you turned blue/grey.

2tweet2b4gotten (author)2016-04-30

DO NOT USE THIS RECIPE FOR INTERNAL COLLOIDAL SILVER. Do diligence. Read more. NEVER use saline in any CS. It turns it to silver salts. Very bad for you. If you follow this guide, eliminate the salts.

Do you have alternative ideas? Can you simply omit the saline?

pattyy (author)2016-04-29

it's called a 1 troy oz.

pattyy (author)2016-04-29

i use got pure silver from coin shop. It's not a coin but it's about the same size and it last much longer.

johnt255 (author)2016-04-22

your silver wires are good until they become brittle and break. your problem lies in one of your other parts. or a missing part

JacobK63 (author)2016-04-13

My silver wires seems to have run out of ions. There are no longer any silver ion that comes out of my silver when I put a charge between them and put the wires in water. Can anybody explain what I can do except for buying some new silver wires? Help is much appreciated.

Hi Sofisintown

I'm wondering if you know I have silver wound dressing. Is there any way I could use it to make liquid silver?

joerobbie48 (author)2015-12-31

Hi Sofisintown
While this preparation with saline is fine for EXTERNAL application, it would be dangerous for internal use. The resulting chemicals formed would include silver chloride which would form a molecule too large to be cleared by the kidneys. It migrates to subcutaneous tissues and is oxidized by UV light to a blue pigment in your skin - - argyria. Please do not take the chance of damaging the reputation of "Instructibles" - such a cool site! Video is exception in quality, and the gizmo is elegantly simple. Thank you!

GregW16 (author)2015-11-02

While salt will allow current to flow, it may create silver chloride, which can cause argyria over time.

Argyria is a condition where
the skin turns grey or blue-grey because of taking high doses of impure
colloidal silver over time. It is very difficult to reverse the
condition, so it should be avoided.

Kiteman and CayeyCase,

Colloidal Silver has indisputable disinfecting and medicinal qualities.
It is not however meant to be downed like double martini's daily.
It is not snake medicine, and it is used widely for disinfection in hospitals, and as antiseptic in wound dressings etc. It is also used as antibiotic in emergency situations.

All your statements refer to Ionic, not Colloidal Silver. Do you know the difference?

It applies to both. Metallic silver is used for it's antimicrobial properties, specifically in devices like the tracheal stoma. Ionic silver is no different, the only change is it's reactivity with other chemicals in solution. I'm not sure why colloidal silver has become a health fad. colloidal silver, or any type silver, taken internally should NOT have any worthwhile properties. The only properties that have changed, between it being in the wire and being in solution, is it's surface area... So it's no different the swallowing silver powder. regardless of type (with the possible exception of some organometallic complexes), ingesting silver is at best useless and at worst suicidal(toxic).

SOFISINTOWN (author)2015-01-24

Ralph, I usually make 1 large glass of water, which I let 'brew' for about 15-20 minutes. Other people might use more water, or longer times, but that's what I do, and works for me.

ralph.webb2 (author)2015-01-24

How much water do you use with this method 27 V 10 gauge 9999 silver wire and how many minutes

szekeres.tibor.71 (author)2014-12-23

Absolutely wrong! It makes AgCl colloid (or more likely just fine suspension) against pure Ag! The ingested AgCl is poisonous. What a good(???) idea!

tony54 (author)2014-02-28

You say not to add any salt then say to add SALINE which is a salt solution !

Yes it is a small amount but like you said that will create silver chloride, what gives ?

I understand why no metal container but why no plastic container ?

Any CHEMISTS OUT THERE THAT CAN HELP the next questions ?

  • Can 1 silver electrode be used instead of 2 since plating usually requires 1 electrode of the wanted metal on the positive and the other metal on the negative electrode. I silver electrode is cheaper than 2 electrodes.
  • Also, is there a way of measuring colloid by conductivity by using 2 quarters or other common STANDARD SIZE of electrode and measuring the conductivity in distilled water ?
  • What is the best current range ? I've heard that a constant current source is better. Is that true ?
  • Should this be refrigerated ?

The FDA and CDC are in the pocket of the drug companies and can't be trusted ! A few years ago, the FDA was trying to classify silver colloid as a DRUG and need to get a prescription for it. To get a prescription for something that is poisonous ? Obviously it isn't. There are MANY patents on it. They also try to say it will turn you blue but leave out that that is VERY RARE.

SOFISINTOWN (author)tony542014-02-28


Tony I am not a chemist. I suggest to use a few drops of previously made CS for conductivity for subsequent batches.

Glass instead of plastic, because some plastics could be reactive.

I wouldn't use any other metal instead of silver. It's easy to mix + and - , and end up with a copper (or whatever) solution.

The commercial CS machines have a 24V-48V range. Lower range produces CS slower, but of better quality (allegedly).

I do put CS in the fridge, for the simple reason that it is -mostly- dark in there, and CS should not be exposed to light. I don't keep it more than a week.

Everyone and their wives is trying to get a patent for CS production, but commercially is not very exploitable, because the said everyone AND their wives can make it at home. However, if you search the internet, there is a gazillion ads selling CS and CS makers, and they all claim that "ours is better than all the others"

The big pharma companies stay away from it, because there is no money to be made, and no exploitable patents, since the stuff has been in existence for centuries.

I would like to know what amperage should be use, do you have any idea?

SOFISINTOWN (author)YoY12014-12-11

Like you see YoY1 I use batteries. I don't know what the amperage is. Just the voltage, which adds up to 27 V

allenmitch (author)SOFISINTOWN2014-12-22

@sofisintown This guy Chuck SmithfixS is just trying to make money off people who check out this site when they "check out his blog". I would delete his comments as well as cranky old Jeffery.liberty. Thanks for the info.

tony54 (author)SOFISINTOWN2014-11-09

I missed where you asked about the no plastic container. Plastic puts off some chemicals in the water like BPA that acts like estrogen causing males to grow breasts and promote breast cancer. Glass also contains some of these but in lower amounts and even many plastics that claim BPA FREE have the same amount in them, false advertizing !
I would never eat from plastic if you have a choice. However, most bottled water comes in plastic and many cities add fluoride and chlorine which is worse than the plastic I think.

I would recommend glass that has been cleaned well before using. Older glass may be better but a chemist / scientist that knows about this is really needed for good advice. I would try to get bottled water in glass or used reverse osmosis filters stored in glass.

I don't think the silver and the plastic react in some way but I'm just following the advice of Bob Beck. Here are some of his instructions and advise in this booklet called Take Back Your Power.

Someone else asked the current, you set the VOLTAGE not the current. I get best results by using 16 volts in HOT WATER for 15 minutes then reversing the electrodes and running another 15 minutes. CLEAN THE SILVER EVERY 15 MINUTES ! It effects the quality of the CS, making it taste bad if you don't and leaves a dark coating on the silver. Possibly silver oxide. It is easily removed by using the green scratch pads for cleaning silverware.
Always us distilled water with NO SALT or other additives. I wouldn't add and CS either since the lower the current the higher the quality of CS.

cathy.lecuyer (author)2014-12-11

How do you know if you make the ionic verses the colloidal?? This is confusing.

tony54 (author)2014-02-28

I've worked in electronics for years as a tech and engineer so I would never mix the positive and negative up. Pretty easy to keep straight, if not use a meter to verify which is positive. Making colloid is basically the same as plating, you are dissolving one metal(the silver anode +positive ), making positive ions,

and plating it on the other the other metal (the negative cathode). You end up with a solution of the positive material so the cathode shouldn't matter as long as it doesn't rust in the water. I don't think it could rust due to the cathodic protection of the electrons. I'm sure only the anode needs to be silver but since I have no way to test it and I'm not a chemist I wanted the opinion of someone that was a chemist, or at least had a good working knowledge of chemistry. Anon of course.

I purchased a $5 Canadian coin 99.99% silver for $27, wish I lived in Canada, and that was the cheapest I could find for 99.99%. 99.9% probably fine but since I will consume it I wanted the best I could find and afford but another $27 is too expensive. I was going to cut the coin in half but it is much stronger than I expected. I think Bob Beck didn't use any salt at all and said to use PURE distilled water. I couldn't find any 99.99 wire. The wire I did find was overpriced.

Bob Beck (his Youtube account was terminated !) people reupload so download and SAVE the videos with Firefox video download plugin.

Checkout patents in and the whole article (6 pages) at article on blood electrification and silver colloid, many other good articles also. He says it cures cancer and many other things, I want to try for myself. The worst thing I've heard is someone's skin turning blue, but that is very rare. making C.S. also.

Treatment of Skin Disease, uses a transition metal (like silver). Search for silver colloid in Google Patents, many patents for something that doesn't work or is dangerous. Now cancer medicines are so dangerous the peoples urine can burn people. And they prescribe this to people ! Same for radiation ! Many cancer cures out there but "only a drug can cure a disease" according to the FDA. I guess that means they were LYING when they said that lack of Vitamin C causes SCURVY, so giving vitamin C will CURE SCURVY even though it isn't a drug ! Not to mention all the other diseases from the lack of vitamins! And if you use the word "cure" you will go to prison reguardless if you are right or not if your not a DR and it isn't a drug !

Checkout the list of companies PATENTS that think silver colloid is effective.

Checkout cancer cures also, many that look effective, therefore illegal to use like vitamin C, D, K, ETC

Butt covering statement:

I am not a DR and this isn't medical advice, it is my advise to educate yourself as much as possible and learn the truth for yourself because I do not know myself, it is only my opinion. Anybody notice the DR notices posted here to make you think you will turn blue and die if you take silver colloid ? So why all the patents ? I believe in Bob Beck but haven't tested anything myself. Learn on your own any beware of any "official statements" from the FDA or CDC who are run by the drug companies.

jeffrey.liberty (author)tony542014-10-01

You seem pretty dumb for an engineer, not knowing the difference between ionic silver and colloidal silver. One is dissolved solids and the other is suspended solids and chemically produce two difference substances which also work in dramatically different ways.

Jeff, sound like you are as frustrated with the Ionic/Colloid ignorance as I get sometimes.

Bob Beck did not know the difference either so I give no credence to his "Protocols" because of that.

Check out "Colloidal Silver Truth" on .

jensenks (author)jeffrey.liberty2014-10-06

Guess you just couldn't figure out a more diplomatic way to say that. Why not make your point and skip the rudeness in the future for a mature discussion?! (Did you see this forum's "Be Nice" policy button when you posted?)

YoY1 (author)2014-11-01

Let said, if I was using 31v dc, what amperage should be use? 1amp?

Chuck SmithfixS (author)YoY12014-12-11

30 milliamps to make a good Ionic, but there is more to it than that.
