Ok thank you, but to clarify, are you saying that doing one of the electrolysis CG formulas without the reduction agent would not result in Gold Chloride?
You need to follow the exact process in all respects. Reducing agents are required. Colloidal Gold is best consumed soon after it is made. Gold Chloride keeps for a long time in storage.
Hi, I'm totally new, have been studying this forum for the past couple weeks, in total planning stage - lots of amazing pertinent info here, loving it..

Please correct me if I'm wrong at any step of this logic process:

1) End product Colloidal Gold produced by any of Kephra's formulas ( is reported by many to have a short shelf life

2) Gold Chloride can be reduced into Colloidal Gold and itself has a long shelf life

3) The Electrolysis methods in Kephra's CG formulas initially create Gold Chloride in the cell, but the presence of the reduction agent in the cell immediately begins to reduce this into Colloidal metallic Gold

4) Therefore (this is my personal reasoning now), it would be possible to create stable Gold Chloride directly by using this same electrolysis method, but without adding the reduction agent

Is this reasonable? If so, any tips/suggestions? I am aware from Neofizz's comment here that Gold Chloride can also be produced by reacting gold with aqua regia, but am curious about directly producing it via electrolysis. (safer?)

Unless my reasoning is wrong, it seems to me the ability to safely produce and store Gold Chloride in advance would allow one to produce CG with less equipment, more on the fly, as situations require.

All input appreciated, im a total neophyte here.
I think you have got it! Good results.
Salt test picture samples of the second batch.

After adding half tablespoon of cooking salt (NaCL) it changed to a ligther color, but no cloudyness or any color change

Tha samples are diluted to 20ppm with regular mineral water
Im using a test tube to isolate the sensor, i fill the test tube with water and put it into the solution while processing

It is worth noting that there will be a slight difference between the internal temperature of the tube and the external temperature of the solution (in my case around 2°C)
Second batch color samples
Finished the second batch, and it looks better now :)

I have added constant stirring now, and changed the becker lid, now the water that evaporates dont precipitate into the container.

I have heated the becker to about 50ºC and then added 1 mL per liter of sodium carbonate solution, and the water remained completely clear.

Then, i have added the Maltodextrin, slowly and sparkling it over the becker, now the water turns white and remaisn for about 5 minutes, till it total dissolved.

Then added the hidrated gelatin (after left it in cold water for 5 minutes) and stirred till the solution reach 65ºC

At this point, i have started the electrolisis, and after 30 minutes the water already looks dark yellow (at about 5 ppm calculated)

The final result does not look opalescent like the last batch, the color remains the same under strong ligth, but its not completely clear like kephra's photos.

The process have been done about 13-15mA, the voltage over the cell always been over 14 volts, constant stirring all the time, and remais in the range of 75-80ºC.

I think the maltodextrin im using is causing the liquid to not be completely clear, whats you guys think about it?

Can this result be less effective than required?

4 grams of gelatin per liter of water.  Gelatin should be added to the water, allowed to bloom, then heated to simmer to dissolve gelatin before electrolysis is started.
hello Kephra, I did add 4grams before i did this batch above and i failed 4 times because the water was turning snowy.
please check this thread.
