A desiccator is used to cool a crucible in order to prevent the absorption of moisture during the cooling process so an accurate result can be obtained
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the experiment.
Placing a heated crucible in a desiccator before weighing allows it to cool down in a controlled, moisture-free environment. This helps prevent the absorption of water vapor from the air, which can lead to inaccurate mass measurements. Additionally, cooling the crucible in the desiccator stabilizes its temperature, reducing the risk of thermal expansion affecting the weight measurement. Overall, this practice ensures more precise and reliable results in experiments involving mass.
The purpose is to avoid absorption of water vapors, CO2, H2S, dust, etc.
The crucible must be cold before weighing because the heat from the crucible will warms the surrounding air

A desiccator is used to remove moisture from the surrounding environment, not to cool down the salt. Cooling hot salt can be achieved by simply allowing it to cool at room temperature or using a cooling method such as placing it in a water bath.

Desiccator are sealable enclosure containing desiccants for preserving moisture
A desiccator is commonly used to extract water from various articles of clothing. Also, if you manage to get your phone wet, you can use a desiccator to remove it.
Crucible tongs are made up of aluminum that used for moving the crucibleswhen they are still hot to cool it down.
The purpose is to avoid absorption of water vapors, CO2, H2S, dust, etc.
Leaving the desiccator lid slightly cracked during the cool-down period allows for the gradual equalization of pressure inside and outside the desiccator. This prevents the formation of a vacuum that could potentially disrupt or damage the samples inside. Additionally, it helps to avoid condensation by allowing moisture to escape, ensuring that the samples remain dry and unaffected by humidity.

Placing hot objects in a desiccator can cause the temperature inside to increase beyond its safe operating range, potentially damaging the desiccant material and compromising its ability to absorb moisture effectively. Moreover, the abrupt cooling of the hot object can create a vacuum or pressure differential inside the desiccator, leading to potential implosions or explosions. It is recommended to allow hot objects to cool down to room temperature before placing them in a desiccator.
Hot materials are not kept in a desiccator because the sudden cooling caused by placing a hot material in a desiccator can create a vacuum inside the desiccator, leading to potential implosion. Additionally, the hot material can release gases or vapors that may react with the desiccant or other substances present in the desiccator.
