A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
The glass on the bulb of a clinical thermometer is thin to allow for rapid heat transfer between the body and the thermometer. This ensures that the thermometer can quickly and accurately measure the body's temperature. Additionally, thin glass reduces the risk of the thermometer causing discomfort when inserted into the mouth or underarm.
The stem of a thermometer is not designed as a magnifying glass. The stem of a thermometer is typically narrow to allow for more accurate temperature readings, as it reduces the amount of time it takes for the reading to stabilize. The magnifying glass may be used for easier reading of the temperature scale on the thermometer.
Thermometer glass is thin to allow for a quicker response time to changes in temperature. Thinner glass ensures that the heat transfer from the substance being measured to the thermometer fluid is more efficient, resulting in a more accurate reading.
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.

mercury
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.

The Mercury-in-glass thermometer was invented by Daniel Gabriel Fahrenheit in 1714. He was a physicist, engineer, and glass blower from Poland.
For a classic thermometer: glass and mercury, colored ethanol or another liquid.

A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
