i was just wondering if any one has tried putting water glass (sodium
silicate) in a printer cartarage, printing the traces, then expose
the water glass to carbon dioxide to make it harden, then etch,
i havent tryed it yet but will soon, i wiil put a dot on a pcb and (i
have some gas to corbonate beer with)and harden the dot.i will see if
the water glass will desolve in the etchant. am working on a
repeater for the ham club now and dont have time. if any one has
tried this let me know,so i will not have to reinvent the wheel.
