it is critical to set the lid just off the lip of the crucible to allow the evolved water molecules to escape on heating.
A crucible is used for heating, melting or calcination of materials.
The percent of water is determined by the loss is mass after heating the water vapor condensed on the crucible wall before heating.
So you don't get burn.
I'm not certain but I imagine it is a combinations of things... Sheffield has a great history of steel making, including 'crucible steel' that was made by heating and melting iron in a container called a crucible. Also, the theatre can be said to be a 'melting pot' of ideas and so likened to a crucible.
a crucible is a metal pot the is used to separate metals. those that are wroth something and those that are not. A crucible is also the name fora witchs cauldron, thus the name of Arthur Millers Text the Crucible.

crucible
the crucible might be hot hence it is handy
The crucible is used for heating small quantities to very high temperatures.
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.

A crucible is a container used for heating substances to high temperatures in laboratory settings. A lid is a cover that can be placed on top of the crucible to prevent the escape of substances during heating and to protect the contents from contamination. Together, they are used for controlled heating and chemical reactions in experiments.
The percent of water is determined by the loss is mass after heating the water vapor condensed on the crucible wall before heating.
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements
The porcelain crucible is used for calcination or melting.
So you don't get burn.
You mean crucible - this is a metal container used for heating substances to high temperatures
