A study of compositions and heat treatment for the development of the ox blood red glaze
A 1915 ceramic engineering thesis by William Owen Rathfon at the University of Illinois, testing glaze compositions and firing schedules for ox blood red copper glaze, written for faculty examiners and kiln technicians. The plates are hand-inked temperature-versus-time firing curves on green ruled graph paper, with sideways axis labels and notes on oxidation and reduction in red and black line.
