Hi
Anyone can tell me how to etch using F.Ch ?
I around 2 years ago use this method. Also I one time etched slice of gibeon
in halt in F.Ch. and another half in Nitric Acid and every half looks
different.

But now I put some F.Ch. to destiled water, put here endpiece of Mundrabilla
finished on powder 600 as I usualy do before I start Nitric Acid etching,
but near nothing happend.
After 10min is there verry pale, dark pattern but this looks ugly.
I must do something wrong but I not remember what :)))

Also I remember that for neutralize Ferric Chloride I used Copper sulfate.
It i also used in PCB etching process.
