Thanks lordkarma. Yes i did catch the bit about boiling it after and that does help a lot. In this case i also topped up the water every 10-15 minutes as it evaporated quickly, and i ended up using a total of 8 liters, double the finished amount!
That and the fact that i used half the recommended salt, this batch has nearly no taste at all! I also added the cinnamon at the beginning and just added all the extra at the end as an after thought.
It did change color a lot also so something happened and i dont know if it is a benefit or not. Was hoping the experts would analyze that and give me some more good advises.
I have already concluded that it must be more efficient to make larger qty's since i used 16X the standard of water (250 ml) and only ran the process 3X longer, 290 min. as opposed to 90 min.
Of course i dont know my final ppm, but using kephra's guess of 25-35 ppm, i am very close to the desired 40 ppm.
And judging from the color changes every hour, i suspect if i ran it for another hour is would be up to the 40 ppm.
I would have liked to keep adding more cinnamon to see where that would go, but didnt want to chance spoiling that big qty. I might pour off some and heat it up and give it a go for experimental sake! And fun too!
I cant really say what benefits i may be getting from colloidal gold yet, but I think there may be some which i will report later when i am more sure. In the meantime it is very satisfying to make colloidal gold and watch water turn to wine.
