Celsius 3 Scale Thermometer - 20 cm Height - Handcrafted in Italy - Pewter
Reverently reproduced, and handcrafted, from an iconic ancient measuring instrument, this beautiful pewter thermometer brings elegant classicism to your otherwise high speed digital day. Cosi Tabellini have patented a special rotating section which makes reading the three different scales of Fahrenheit, Réaumur and Celsius even easier.

By producing this beautiful pewter thermometer, Cosi Tablellini pay respect to the pioneers of temperature measurement: Daniel Gabriel Fahrenheit, René-Antoine Ferchault de Reaumur and Anders Celsius.
Fahrenheit, in 1714, was the first person to use mercury in a thermometer. Mercury expands more predictably; this, as well as improved glassworking techniques, meant the thermometer was more accurate than ever before. Fahrenheit divided the freezing and boiling points of water into 180 degrees. 32 was chosen as the the figure for the lower fixed point as this produced a scale that would not fall below zero even when measuring the lowest possible temperatures that he could produce in his laboratory - a mixture of ice, salt and water. Fahrenheit used the newly discovered fixed points to devise the first standard temperature scale for his thermometer. The Fahrenheit scale is still in use today.
Réaumur, in 1731, proposed a thermometer scale on which the freezing point of water was 0° and the boiling point was 80°. The Réaumur scale is seldom used today, although it is still used by some Italian and Swiss cheese manufacturers for measuring milk temperature, such as Parmigiano-Reggiano and Grana Padano cheeses, and also used in the Netherlands for cooking sugar syrup for desserts and sweets. Réaumur is still remembered as one of the key pioneers in developing the thermometer.
Then in 1742 Celsius devised a thermometer scale dividing the freezing and boiling points of water into 100 degrees. He chose 0 degrees for the boiling point of water, and 100 degrees for the freezing point. In 1743 Cristin sensibly inverted the Celsius scale, freezing point 0° and boiling point 100° to produce the Centigrade scale used today. Just over a century later, it was agreed that Cristin's adapted scale should be referred to as Celsius and is still in use today. Cosi Tabellini named this thermometer 'Celsius' in honour of his achievements as a key contributor into the evolution of the thermometer and temperature measurement.
