Homebrew PCBs

I wonder if the Tarn-X is leaving a micron thick film
of some sort, or an electrostatic charge or an ionic
bond for the ink to grab before being roasted dry.

I don't recall Steve using Tarn-X in his experiments. 
My wife uses Goddards jewellery cleaner, (don't know
whether this is the same thing) and it does strange
things to some metal oxides as I recall.

Eye of frog and tail of.....

Something is happening here which allows Volkan to
achieve such good results.
