August 24, 1993

Although I was no longer assigned as print shop assistant, the print professor asked me to help get the shop ready for the beginning of the semester, including mixing the acid for intaglio classes. We had two tanks going in the acid room- one 8:1 (water:nitric acid) for stronger etches, and one 15:1 for aquatints and other more delicate procedures. In each case I'd fill a large beaker with water and dump it into the tank the necessary number of times, then add the proper amount of nitric acid to the water, after taking care to put on respirator and protective gloves.
