Virtue No. 237 – “Ding! Fries are done…”

Of electro-etching’s many virtues, one of the best is the simple fact the etching only occurs when an electric current is flowing. No juice, no etch. Perfect for the multi-tasking, absent-minded, and easily-sidetracked artist, this is truly a gift from the Print Gods. Simply work a timer switch into the circuit and your plate will etch for the precise time needed, no more, no less.
