“Chemistry of Combustion and Illumination” is an intriguing illustration from the Chemical Atlas; or, The Chemistry of Familiar Objects, authored by American scientific writer, editor, and lecturer Edward Livingston Youmans (1821-1887). This captivating color plate, known as Plate XI, visually depicts the intricate processes of combustion and illumination. Within the flame’s structure, the currents of gases are elegantly indicated by directional arrows. Youmans, a pioneer in popularizing science, founded Popular Science magazine. His work continues to inspire curiosity and understanding in the realm of chemistry and natural phenomena.
