Sandpaper Aquatint with BIG Ground

In this series of experiments we tested different sandpapers to created a smooth even aquatint on a copper plate grounded with BIG. We used different grits of sandpaper on the plate and ran it through the etching press to create an impression which we etched in the Ferric Chloride bath. We discovered the best grits of sandpaper to use, how to prep the plate before etching, troubleshooting issues with the ground flaking off, and removing the BIG after etching.
