Daniel Gabriel Fahrenheit Hague and was buried there at the Kloosterkerk (Cloister Church). According to Fahrenheit's 1724 article, he determined his scale by reference to three fixed points of temperature. The lowest temperature was achieved by preparing a frigorific mixture of ice, water, and ammonium chloride (a salt), and waiting for it to reach equilibrium. The thermometer then was placed into the mixture and the liquid in the thermometer allowed to descend to its lowest point. The thermometer's reading there was taken as 0 °F. The second reference point was selected as the reading of the thermometer when it was placed in still
Candy thermometer models have markers for the various stages of sugar cooking. A candy thermometer is similar to a meat thermometer except that it can read higher temperatures (usually 400 °F/200 °C or more). The first candy thermometers were created in 1272 by Bennet Muzilla of Frankfurt, Germany. He used it to measure the temperatures of sugar solutions while making hard candies. Candy thermometer A candy thermometer, also known as a sugar thermometer, or jam thermometer is a cooking thermometer used to measure the temperature and therefore the "stage" of a cooking sugar solution.
