I'm assuming you mean a crucible and lid (the little white things you place in ovens or on the top of Bunsen burners)?
If you do, then a crucible and a lid is a way to get an anhydrized solid (a solid which may have H2O mixed in amongst the pure solid) and turn it into pure product by evaporating away all of the water in the solid.
A crucible with a cover is commonly used in laboratories for heating, melting, or mixing substances at high temperatures. The cover helps contain the heat and prevent contaminants from entering the crucible during the heating process. This setup is often used in processes such as chemical reactions, metal alloy testing, and sample preparation in analytical chemistry.

Why is it necessary to cover The Crucible by Arthur Miller when it is being heated?
It is necessary to cover the crucible when it is being heated for two basic reasons: primarily, it maintains a higher temperature inside the crucible. Without the lid, the heat simply escapes. Secondly, it keeps the material inside the crucible from splashing out.
