Coffee maker set up help & info
« on: August 22, 2020, 11:28:09 PM »
I am making my own Colodial Silver using a bunn coffee maker it is about 1 quart distilled water with a 12V power supply and 2, 1oz silver bars. I dont know the exact water temp. Do I need to leave the jar on the coffee maker hot plate to maintain a hot temp or is just heating the water good enough roughly how long will I need to let sit in production to make 100ppm. Also I have a 9v power supply would I be better off to use the 9v supply and longer production time? And Lastly what would the shelf life for this silver be

You need to read the articles section - all numbered articles.  There's more to making Colloidal Silver than plunking a couple silver anodes in water connected across a power supply.

You need an electrolyte, a current limiter, a voltmeter, reducing agent, you need to use Faraday's law to compute the run time to get to the PPM you want,...  The procedure is simple but you have to do it right.

You also need a higher voltage power supply (18V+) to use with the limiter. The reason is that you always want 10V minimum across the anode/cathode, 11-12V+ is better.

Once you have a good setup, depending on the PPM and the current you've chosen to run you may be able to run cold but for PPM's higher than 20, you have to run up around 150F because with higher PPM's you have to add the reducing agent at the beginning of the run to do continuous reduction and reducing agents reduce slow as snails at room temp.

There's science involved and you have to do it right but the procedure is simple and the cost of a simple setup is probably less than $30 including the voltmeter. That is excluding the cost of your silver anode.

Oh yeah, your cathode (minus) can be copper wire and thats what we use. Silver only comes off the anode. Nothing comes off the cathode.  You adjust cell voltage by raising or lowering the cathode. The less under the water, the higher the cell resistance and hence the higher the voltage.  The more in the water, the lower the cell resistance and the lower the voltage.

You need the voltmeter to measure the voltage across the cell so once you start the run you can adjust it to get it up over 10v and you also want to check the current to make sure everything is fine. With a 1oz bullion bar for the cathode, you will find it impossible to get the cell voltage up over 10V.  We use these days a thin (like 24 gauge) copper wire and with this you'll have maybe 3/4" submerged.  Just think about the surface area of that 3/4" piece as compared to the minimum you can submerge with a bullion bar and you'll see what I'm talking about.

Properly made Colloidal Silver should keep basically forever, especially if its gel capped. Karo as a reducing agent is only good up to 20PPM.  If you want higher and choose not to gel cap, your best bet is maltodextrin. Its not only a reducer but a great stabilizer which lends to long storage life.
