Historical Electrolysis Apparatus Diagrams - 19th Century Scientific Illustrations #3252098 (License: Personal Use)

The left diagram (Fig. 11) shows a vertical rectangular electrode suspended in a liquid-filled glass vessel, likely for controlled current passage. The right diagram (Fig. 12) features a helical or looped wire electrode submerged similarly, suggesting variation in surface area or gas collection design; both include stoppered stems and are rendered in fine-line engraving style typical of 19th-century scientific publications.

Used in educational materials, museum exhibits, or historical science blogs to illustrate early electrochemical experimentation; targets users researching the history of chemistry, physics instrumentation, or Victorian-era laboratory practices.
