Updated: Aug 23, 2019
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
