Just from experimentation, observation and experience... I get better
results in an iffy situation from the old pitted electrodes. A batch run
at marginal current density is less likley to go yellow with the rough
electrodes. They 'might' contribute to a stronger TE but can't draw any
cohesive conclusions there. Apparently TE varies according to several
factors..too many to nail down.
Grain boundaries sounds good. Face centered cubic crystals would have
lots of points. Since the wire is probably drawn to dimension, there's
probably a lot of microscopic stress fractures as well...and/or tooling
marks? Like, how smooth is smooth and shiny to an ion? They probably think
they're flying out of a Himalayan heliport.
I "swear" that oxidation has something to do with the growth of large
particles. Crystals tend to grow around 'something' and while a yellow
particle may not have it's color determined by oxygen content, that doesn't
mean it didn't grow around an oxygen atom or two. How many silver ions will
fit around a single oxygen anion?
H2O2 does strange things to both pure silver metal and oxides..turns the
electrode metal black after it cleans it off, breaks up oxides AND clears
out various colors. If I use even a little H2O2 in the water, I get really
big shiny silver snowflakes suitable for a metalflake paint job...which if
left alone for months, turns into a white precipitate.
If I use highly ozonated water, it's much more likely to have a batch go
yellow than if the very same water is vented for a few days. [bubbles form
on the sides of the jug]
So, just maybe using low current density makes any oxide formation occur
close enough to the electrode for it to get stuck there. [Yea, I know,
nothing about this can be that simple]
..and, and and....orbut
Wonder what would happen if the generation chamber had a fairly strong
vaccuum? ..strong enough to suck dissolved gasses out without evaporating
the water too fast.
..would current density suddenly not matter all that much?
..would ions remain ions?
..really high and small particulate content with no colors like a liquid
mirror?
On that note:
The last batch I ran at ULVDC has a strange tendency to pick up any color
around it. If I take it outside, it's pale clear green. [mega forest]
Inside, it's pale yellow [lots of yellow pine in here] Held up to sunlight
or wrapped in white paper, no color at all. Won't pick up other colors like
red and blue or even blue green.
I've noticed that effect with some batches that had no color but did have
a somewhat heavy TE. {This batch has a very faint TE}
Have I made CS with metallic particles so small that the red and blue light
has a hard time finding them?
