Hi folks,
After a couple of years of focusing mostly on colloidal gold, I've fixed up my little homebuilt Colloidal Silver generator, which does 5mA constant at up to 60 V DC.
Now I'm looking to try out different formulas. I've always either used heat reduction or maltodextrin, which seems to work well. Judging by color, I would say malto can do over 100 PPM, though there is some turbidity when running it that hot.
The other day I did a very gentle production run of 50 PPM Colloidal Silver with no heat at all. 500ml cold water, maltodextrin in right away and then alternating between running and pausing to let the reduction catch up for 25 minutes at a time. It came out a nice, clean yellow. Though the flashlight still showed a little bit of turbidity. Leading me to believe that it's impossible to make it 'perfectly'. At least by these methods. I couldn't produce it more gently if I tried.
Ordered some 70% spirit to try cinnamon and vanilla extract. My head is spinning from all the forum posts I read already, but maybe someone can summarize their findings or just shed some light on this question. How high is the PPM you've achieved with maltodextrin, cinnamon or vanilla extract? I am not looking to gel cap, but would like to find a reliable reduction agent with little turbidity up to 100 or even 200 PPM. I would also like to use something other than carbs for my ultrasonic nebulizer, because they might gum up the works. So far I understand cinnamon extract may be my best bet.
