Description

A rare survivor of the Georgian era. A pocket hydrometer used to measure the strength of alcohol on a scale of 1-10. Weighted bulbous end (lead ball/shot?) ensured that the higher the alcohol content, the lower the bulb would sink in the solution (10 being pure alcohol or high proof based on density). The stem is graduated on both sides. Made of three parts and silver soldered together, it shows little wear. The turned walnut, two part  case is flawless and closes by friction fit. Measuring only 2 1/2 x 1 inch (3 x 1 + inch cased) or 7 x 3 cm., this simple device was carried by inspectors to ensure the quality (alcohol content) of spirits, wine and beer in a time when “watering down” of such was common place and the industry was just becoming standardised. The more common and elaborate sets (including thermometers) were retailed by Sikes in Victorian times. Unmarked.
