electro etching

I recently “met” Marie Fredriksson on facebook and she made me think about electro etching. I decided to give it a try as the mandatory materials are quite easy to find at least for a few tests.
So here is my first try on steel, made with a basic 9V battery.

I will have to find another varnish and to buy a power supply with a stronger amperage if I want to achieve a deeper etching but it looks promising, doesn’t it ?
