Before using the thermometer we need to wash it with normal drinking water and then shake
it down, like this.
Shaking it down will move the mercury from this end to the tip.
Ideally, before taking temperature, mercury level should be below 97°.
Now place it underneath the tongue and hold it right there for two minutes.
Mercury thermometers could be used orally, rectally and under the arm.

Glass Thermometer Review
The mercury-in-a-glass or mercury thermometers were invented by German physicist, Daniel Fahrenheit, in 1797 in Amsterdam. It is actually a mercury lamp bulb with a large mercury drop on one end of the bulb and a glass tube filled with water. The fluid level in the tubes is significantly less than that of the bulb; thus, the temperature in these tubes is significantly cooler.
These days, there are various kinds of thermometers available in the market, all of which are designed to give accurate readings about the temperature inside any kind of glass container or thermometer. Some are made with platinum in silver with gold-colored strips; others are made of clear glass with silver strips. You may select the type that best suits your need and the application.
The main advantage of the mercury-in-a-glass thermometers is that it is very convenient to use. There is no need to handle the mercury or put it inside the container to get the readings. You just need to place it on the place where the temperature is expected and wait for the readings. The temperature of the fluid can be calculated with just one hand and there is no need to be concerned about the accuracy of the readings.
You can use mercury-in-a-glass thermometers anywhere, even in a hot car. You can just take the thermometer and place it on the dashboard so that you can keep a track of the temperature in your car’s dashboard. You can then take the temperature in the vehicle to the nearest restaurant for dining or take it to work so that you can check on the temperature in your office cubicle.
You can also use glass thermometers in the laboratory, in labs, and in schoolrooms. These thermometers are ideal to measure and record the temperature inside a sealed container without needing to open it. You can do this while keeping your hands busy or while studying in class. The thermometer can also be used to test a substance inside a bottle in an alcohol test kit so that you can know the amount of alcohol present in the bottle before you drink it.
If you are a teacher, you can use glass thermometers in your classroom so that you can keep track of the temperature in the room where the students are. If you have small children at home, you can use the thermometers in your garage to monitor their temperature. They can be used in their rooms as well. Thus, they can be a useful tool for teaching and learning. You can also use these thermometers in hospitals and nursing homes, so that the patients can be monitored properly so that they can be properly treated.
