Left to right copper has been left in for 15, 30, 45, 60 & 75 minutes

Using ferric chloride acid- fresh mix 2:5 ration pieces left at 15 min intervals

comparison between a 15min tile and 75 min tile



Brass etched 15 mins


Silver etched 60 mins Really like the depth of this etch



Copper etched 30 mins

I really like the pitted texture through all the different metals
