A crucible is a cylindrical container made from a material that can withstand high temperatures. These are often used to melt metals or other materials.
Historically, crucibles were most commonly made from clay but now they can be made from any material that can withstand high temperature. They can also be shaped into many different shapes and sizes.
copper crucibles are a type of crucible that is used for smelting and melting of copper and its alloys. They are used in a variety of applications including making electrical cables, pipes and other wires.
The earliest crucibles were created in the Roman period and were used for smelting and melting of leaded bronze. These were shaped like traditional ceramic crucibles but were more narrow and flat to sit within a furnace.
In the Medieval and Post-Medieval periods new crucible designs were created by a few specialists. These included triangular crucibles known as Hesse crucibles from Germany, which were produced on wheels or inside molds using high alumina clay.
A crucible must be designed for its particular operation and the characteristics of its operational conditions. It should be able to handle the rate of temperature change and be resistant to thermal shock, both of which are important in foundry applications where temperatures can change by several hundred degrees in seconds. It should also be able to withstand corrosion and erosive environments. Selecting a crucible that meets these requirements can be challenging, but it is crucial to your operation’s success.
