FOR THE ADVANCED STUDENT: THE MAKING OF 320 PPM COLLOIDAL SILVER & GEL CAPPING TIPS
From Kephra's other posts on the subject:-
A)
I never heat my 20 ppm unless I want to gel cap it. Normally, it takes less than an hour to fully reduce. But I use a ml of Karo per liter of colloidal silver.
The best way to gel cap 20 ppm colloidal silver is:
Add 1 gram of gelatin to 8 ounces of colloidal silver.
Let gelatin bloom, then heat enough to melt the gelatin.
Mix well.
This will by your stock gelatin solution.
Then heat your new colloidal silver to the temp required to melt the gelatin (approx 100C)
Add one tablespoon of your stock gelatin to the colloidal silver, and heat for a few minutes.
Stir well.
Let cool.
Done.
Refrigerate the remaining stock gelatin solution.

320 ppm Gelatin Capped Metallic colloidal silver
Warning: Should be diluted to 20 ppm before use.
250ml cold distilled water
1.0 gram or 1/4 tsp Knox unflavored gelatin
Electrode spacing 1.5 inches
Add 5 drops 1M Sodium Carbonate
Add 15 drops clear Corn Syrup (diluted 1 to 1 with distilled water)
Electrolyze 80 minutes @ 15ma
Constant stirring and heat required. Heat water to a simmer (about 200F)

GEL CAPPING TIPS
Here are some guidelines for using gelatin to make/cap silver nanoparticles:
An electronic scale, a heated stir plate, and chemical thermometer are recommended.
How much to use: (based on results with 320 ppm silver batches using Knox brand unflavored gelatin):
Calculate minimum mg of gelatin = ppm X ml /160
Calculate maximum mg of gelatin = ppm X ml /80
This amount will give good results. Other members report success with less. The amount is for Knox brand unflavored gelatin. Other brands may require a different amount.
For 20 to 40 ppm, add the gelatin after the electrolysis. For ppm > 40, add the gelatin at the start.
Add the gelatin to the water when cold and let it sit (bloom) for several minutes, then heat it to 60C until the gelatin dissolves, then start the electrolysis for ppm > 40, or just allow to cool if the electrolysis is finished.
For making high ppm (greater than 40 ppm) the gelatin should be in the water during the electrolysis.
Always add the gelatin to cold distilled water by sprinkling the powder on top so that there are no clumps.
Let the gelatin soak for 5 minutes or longer to absorb water before applying heat.
Apply stirring if you have a stirring device.
Apply heat so the mixture warms up slowly, allowing all the gelatin to dissolve. 60C (140F) is sufficient.
Keep the temperature of the solution above 140F/60C minimum to 190F/88C. Avoid boiling to prevent excess evaporation.
Use the appropriate amount of reducing agent (based on water volume and ppm) IE: 4 to 5 drops diluted corn syrup for 1 cup of 320 ppm colloidal silver (ppm*milliliters/16000).
Use the appropriate amount of electrolyte (based only on water volume at 20 drops 1M sodium carbonate per liter) IE: 4 to 5 drops for 1 cup of 320 ppm colloidal silver
Reduction is much slower with gelatin in the water, so the solution must be kept warm for some time after the electrolysis is complete for the color change to occur indicating full reduction.
Gelatin capped colloidal silver will be darker in color due to the weight of the gelatin dragging on the surface electrons of the particles.
D)
Alternate Method for 20 and 40 ppm colloidal silver:
Make gelatin solution by dissolving 1 gram of gelatin in 250ml of water or 20 ppm colloidal silver, and heat until dissolved.
Add an appropriate amount of this solution (try 1 teaspoon for each 250ml/cup of warm (140F) colloidal silver and allow to stand and cool for at least an hour.
These guides are based on experiments by Kephra and RickinWI and are suggested as a starting point, and may not be optimum. However following these guides will result in quality colloidal silver nanoparticles.
Store unused gelatin in the refrigerator, and replace frequently to avoid spoilage.
Karo can be diluted with vodka.
'cold' means room temperature. Allow a few minutes for gelatin to bloom.
Heat to temperature before starting electrolysis.

From GOTOGUY's other posts on the subject:-
This is the methodology that i have came up with, which seems to be working very well hopefully this helps you out. one side note though I am working with large amounts [4500ml to be exact] so my methods take this into account and but maybe it will still help answer your questions I will try to be as detailed as possible. . .
--1] I preheat my 2 half gallon mason jars and a 3/4 [750ML] quart jar in a slow cooker. This gets the temp to about 145[this save the microwave ALOT OF WORK] . I then put the to half gallon jars in the microwave for about 20-30 minutes to get to about 195-200. . now I have my 750ml of prewarmed water and my 250ml pre mixture. . . . [my pre mixture is about 250ml of "cold" room temp water with the electrolyte and karo in it but no gelatin]
--2] I then add the the premixture aka [250ml cool water] plus the prewarmed [750ml] 145 temp water to the 4500ml beaker making it 1liter full .
The first time I tried adding gelatin to cool water it failed miserably and globbed up everywhere, So im not exactly sure where the cool water comes in BUT from my experience gelatin does not mix well in cool water or even medium water, from my experience it seems best arround 170 or hotter to completely dissolve. NOTE: for me I have to SLOWLY add the gelatin to to my hot warming up liter, while under high 1500rpm stir and under max heat. Adding it all at once results in globbing up adding it when to cold results in it globbing up. . . when its all added allow to it to continue to stir on max stir and heat my half gallons are still reaching temp . I then temporarily stop the stir and check the clarity to make sure its ALL DISSOLVED. Since this seems globbing up has been a occasional issue. . .[I've brewed about 7 gallons of 320 so far] Once all good I start stirr again and at this point the water is about 180 and my half gallons are at about 195-200 in the microwave
--3] I now add the scorching hot half gallons to the mix [this makes me so nervous, moving that heavy scorching hot jar from the microwave to the table]
Once my the half gallons are added the whole 4500ml is around 190-195 [Ideal temp is 200 but for me thats hard to reach since its so much water, but i occasional do, my temp always stays between 190 and 200 threw the whole run
--4]I now start my electrolysis for me that is 2 hours and 44 minutes at a 130ma[this is not a normal ma, but I have very large anode]I then put a box over the beaker to keep it dark [kephra wrote an article on how light alters particle size and its best to have no light or red light to keep smallest particles] I also have it on a count down outlet timer to time the batch just right. . . .
2hours 44 minutes later im all done. . .
I'm not sure if its the best practice but it seems to be working well for me so far. Im still confused the cold water transition to hot water part and at what tif there is a specific order to add/start each process but it seems to be working well so far. . .
