MAKING RED LEAD. “Grind flake-white (note: lead oxide) on a stone without water, then put it in two or three new pots and place it over a burning fire. You have a slender curved iron rod, fitted at one end with a wooden handle and broad at the top, and with this you can stir and mix this flake-white from time to time. You do this for a long time until the red lead becomes completely red.”
