Effect of size of gold on process

(1/2) > >>

imcool:
I am making more colloidal gold by electrolysis process as mentioned below:
40ppm (approx) Colloidal Gold, Electrolysis I

250 ml hot distilled water
100 mg sodium chloride (table salt ok, NOT sea salt)
110 mg trisodium citrate monohydrate
Pure gold anode, copper cathode.
1 ml Cinnamon Extract
Electrolyze with 350 milliamp current for 25 to 30 minutes
Constant stirring and heat required.


As I cant get my hands on gold wires right now, I used 10grams gold bars to create colloidal gold water which you can see here,

As I have to keep amps as per the instruction, My question is, if i use bigger gold bar,(double the size)  will the time remains same to prepare colloidal gold?

thanks  a lot for replying

I would expect a bigger anode to take longer.

I found it better to use a very small anode and a large cathode, just the opposite for silver.
 
You will just have to try it.

The formula given is to reproduce my results.  My power supply would not supply any more current than that.  If I had more amps available, I would have increased it.

thanks a lot for replying, i will experiment, i am also planning to join two gold bars together without soldering or any metal, maybe i will use a  rubber band or zip tie

Bill, can you elaborate more on your formula with the smaller power supply?  I bought a PSU for making silver, and I think I'm in the same boat as you, would you share your details please?

I used bigger gold bar 1.83inch length x 0.63 inch width x 0.05inch (thick) and made 800ml colloidal  gold water without any issues at 350mA and Cathode copper wire was 2mm diameter 1.83 inches long . have a look at the final product here
