Being the only metal which is liquid at room temperature mercury has some specialist uses: It is also used in barometers an manometers due to its high density. From this it has also become a way of measuring pressure in millimeters of mercury. It has also been used as liquid electrolyte for the production of chlorine and sodium hydroxide from the electrolysis of brine but is again being phased out in favor of safer alternatives. It is still sometimes used in electrical switches as a liquid contact. Mercury also used to be used as a component for dental amalgams for making fillings for teeth. This process has again been phase out due to health concerns but many people still have mercury containing fillings and crematoria are thought to emit about 5kg of mercury each year simply from dental fillings. The amalgam of 70% silver and 30% tin when mixed with mercury formed a pliable material that could be inserted into the tooth and the amalgam expanded as it dried to fill the entire cavity. However this amalgam has been replaced by a similar one made from 60% silver, 27% tin and 13% copper.
Mercury is still used in a variety of products and processes, such as dental fillings, thermometers, fluorescent light bulbs, and industrial applications like mining and chemical production. However, due to its toxicity and environmental impact, there are ongoing efforts to reduce and phase out its use where possible.

Before mercury what was used to fill thermometers?
Alcohol, usually ethanol or colored alcohol mixtures, was used as the filling in thermometers before mercury.
What metal element is used to make thermometers?
Mercury is the metal element traditionally used in thermometers due to its ability to expand and contract uniformly with changes in temperature. However, due to its toxicity, mercury thermometers are being phased out in favor of digital alternatives.
What kind of paper contains Mercury?
Thermal paper used in receipt printers may contain small amounts of mercury. This is because mercury is sometimes used in the manufacturing process to enhance the paper's properties for thermal printing. Proper disposal of used thermal paper is important to prevent mercury contamination of the environment.
How do you mix copper sulphate with mercury?
Mixing copper sulfate with mercury can be dangerous and should be avoided. The reaction between them can produce toxic mercury vapors and may lead to health risks. It is recommended to handle these chemicals with proper safety precautions and avoid mixing them together.
