Hi Tom, Cool. Did you get any bubbles with the sodium bicarbonate? Wonder where the CO3 - or 2 part went? Possibly the silver is oxidised and lying at the bottom all tuckered out (my WAG), possibly you've made some sodium ascorbate from the baking soda?? The color effect might be the difference between what colors your brew Transmits; i.e. dark amber, and what it Reflects; bluish grey? If no Tyndall, how come the diff between transmitted and reflected light? Tyndall doesn't just mean big enough to see sparklies, ya know, so what is interfering with the light? - truly tiny microscopic particles, I'd guess, so Tyndall-time. And another angle is the sorta complementary relationship (color-wheel) between amber and blue-grey.
Well, hey; onward and upward M.
