Small LEYDEN JAR
c.1780

Unsigned
Flat bottle of thick glass, outer coating painted over with red paint and gold motif. Jar filled with gold foil (inner coating), with central brass discharging rod and ball.
Leyden jar discovered by Kleist in Germany (1745) and Cunaeus and P. van Musschenbroek in Leyden in the same year; hence given the name of 'Leyden jar' by Abbé Nollet (1746). First jars filled with water and hand acted as outer coating, but these were soon replaced by inner and outer coatings of metal foil (Bevis. 1746).
