                                Chemical chart of solutions and precipitates of copper and lead salts in wine glasses, illustrating the colour of each. Figure 67 shows copper oxide salts in seven solutions, including (number 7) with an iron zinc plate. Figure 68 shows lead in seven solutions, including (number 7) with a zinc plate. Above are two inset figures intended to show the colours of copper oxide in weak and concentrated solutions contained in bottles.    
Figures 67-68 from Das Laboratorium…v.1 (Weimar, 1840). Inscribed above ‘Taf: LXVII. LXVIII.’ Figures are headed ‘KUPFER’ and ‘BLEI’ and there is a numbered key to each solution beneath the images.
