Historical Thermometer in Goblet - Early Scientific Instrument Illustration #283324 (License: Personal Use)

This black-and-white engraving illustrates an early experimental setup where a U-shaped glass thermometer is partially submerged in liquid within a stemmed goblet. The fine hatching indicates liquid volume and surface tension, while the base’s concentric rings suggest stability and ornamental design typical of 19th-century scientific illustrations. Such diagrams were common in physics and chemistry textbooks to demonstrate thermal expansion principles.

Used in educational articles, museum digital archives, or history of science webpages to visualize historical instrumentation; matches user intent for researching vintage lab equipment or the evolution of temperature measurement.
