You can't weigh a hot crucible because its temperature can cause air currents and convection, leading to inaccurate measurements. Additionally, any moisture or volatile materials on the crucible could evaporate or change weight as it cools, affecting the accuracy of the reading. For precise measurements, it's important to allow the crucible to cool to room temperature before weighing.
heat rises. less mass i think
A pot that hot enough to meth the metals.
The content in a crucible is not weighed while hot because heat can cause air currents and thermal expansion, leading to inaccuracies in measurement. Additionally, any moisture or volatile substances may evaporate or escape, affecting the mass of the sample. Weighing when the crucible is cool ensures a stable and accurate measurement of the substance.
Hot as fire
A crucible must be cold before weighing to ensure accurate measurements. If a hot crucible is weighed, it can cause air currents and thermal convection that affect the scale's reading, leading to an inaccurate measurement of the crucible's weight. Additionally, weighing a hot crucible can risk damaging the balance or scale. Lastly, cooling the crucible allows for any residual materials to settle, providing a more precise weight.
Crucible tongs are made up of aluminum that used for moving the crucibleswhen they are still hot to cool it down.
Adding water rapidly to a hot crucible might cause the crucible to brake.
the crucible might be hot hence it is handy

Manipulation of hot crucibles to avoid burns and contamination of the crucible.
Adding water rapidly to a hot crucible can cause a violent steam explosion due to the rapid conversion of water into steam. This can lead to splashing of hot material, potential burns, and damage to the crucible and surroundings. It is important to add water slowly to prevent this dangerous situation.
Crucible tongs are huge forceps that are used to hold a hot crucible and remove it from the furnace. Crucible tongs are made from steel that can stand high temperature.

You can check the temperature of the crucible by gently touching it with the back of your hand. If it feels cool to the touch, then it has likely returned to room temperature. Alternatively, you can use an infrared thermometer to measure the temperature of the crucible.
