Homemade Photoetch - Rhein Gold part 2

Now the trick for etching brass is that the etching must be the fastest possible.

That means that the bath musn't be clogged, the Perchlorure de fer (okay, can't remind how to say that in English), it must also be stirred and heated

So in an old aquarium I put 2 liters of the acid, an aquarium heater and air pump and dipped the fret in it.

You can see pretty fast if things go well. look below the parts pop out of the metal
