I'm trying to make smaller particles as far as possible.
My batches are always little gray with metallic taste and hardly perceptible yellow tinge. I think that they have more ions and little colloids.
Concerning the potency of solution I judge by strong laser beam and final clearness.
I also believe in small particles like you that's why I don't touch the resistor. But I'm wondering one thing.
What is the best resistor for my silver strips? When I have smaller silver wires, this resistor works fine but now I think that I need another one. What would you suggest? How much ohms to get for bigger electrodes like new strips? 10,20 or 70 ohms?
