CAN somebody please tell me; what amount of Ferric Chloride (anhydrous) to be mixed with what amount of water for etching one 9cm x 5cm board.
Please!!!!!
Hi, well, you don't worry about that, thats easy just fill the water first and then add small pieces of ferric chloride till the mix gets darker, when you just stop seeing thru the mix stop adding the pellets.
What helps most this kind of mixes is a little of heat and shaking a little.
Warning: That stuff is toxic !!! And it damages most clothes, others can be clean with anti ferric chloride.
