Original use
The ordinary mercury thermometer is a measuring device for temperature determination, the operation of which is based on the temperature extension of mercury. It is used as a thermometer in the weather house, which is positioned two feet above the ground. It is an oblong glass pipe, filled with mercury. The volume of mercury increases with the increasing temperature. The temperature is read by determining which mark on the pipe is reached by the column of mercury. For the purpose of more accurate reading, one end of the glass pipe has a round-bottom flask, which contains the majority of mercury. The expansion and contraction of the mercury volume is relatively larger in a pipe with thin cross section.
Present use
The mercury thermometer is being preserved, secured and presented as important mining heritage of Idrija with exceptional universal values. It is a part of the CUDHg Smelting Collection. Visitors can view them within the permanent museum display “From Ore to Mercury Drops” in the Hg Smelting Plant, which represents the characteristics and the versatile use of mercury in science, technology, medicine, culture and every day life. Within the exhibition, the object is placed in the thermal expansion segment and it represents the usefulness of mercury for technical devices.
