SHEETS ETCHING
 Products are mixed in the jar.

 The sheets are plunged in the bath, bubbles appear quickly and the bath color becomes green.

 

The chemical reaction races, heat and emanates more and more gas.

The 0,2 mm thick brass is completely etched in 12 minutes!
If you don't want to completely etch the metal (like for the license plates), 5 minutes are enough.
