The same thing is happening to me, except I'm sure it's not the container.
I'm new to this forum; I have been making what I thought was true colloidal silver, but I've learned is actually ionic silver. I'm using a basic setup- (3) 9v batteries wired to (2) 10 guage silver wires in a clear glass of distilled water, no electrolyte. I have made several batches and I read a tip that using a little bit (1 oz or so) of IS/Colloidal Silver from a previous batch can increase the conductivity of the water... so that's what I have been doing and it seems to get the process started quickly.
I let the batch "brew" for around 30 minutes or so, stirring occasionally. The result is a yellow-greyish solution with a fair amount of large chunks. I pour the solution through a *white* coffee filter and into a clean glass. I am left with a solution with zero visible chunks that has the color of perhaps a weak sun tea (yellowish, not grey at all). When drinking it, there is no metallic taste initially, but you do notice an aftertaste. I was drinking about 16 oz or so during the first few days but have stopped because I'm now a little confused as to whether it's ionic or colloidal....
Is this normal? I though ionic silver would not be yellow.
Thank you in advance!
