What is a crucible used for in science?
Used from ancient times as a container for melting or testing metals, crucibles were probably so named from the Latin word crux, “cross” or “trial.” Modern crucibles may be small laboratory utensils for conducting high-temperature chemical reactions and analyses or large industrial vessels for melting and calcining …
How is crucible used in laboratory?
Crucibles. The porcelain crucible is a laboratory material used mainly to heat, melt, burn, and burn substances. It is a small container which has a cavity responsible for melting and calcining. To melt and heat with the porcelain crucible gloves or tongs must be used to remove it from the flame.
What is chemical crucible?
In chemistry, a crucible is a kind of laboratory equipment that is usually a small cup, about the size of a shot glass, made of porcelain or non-reactive metal. Crucibles are used to heat chemical compounds to very high temperatures using a gas burner.
How does the crucible work?
A crucible is a pot that is used to keep metals for melting in a furnace. Furnace crucibles are designed to withstand the highest temperatures encountered in the metal casting works. The crucible should essentially be made of materials with a much higher melting point than that of the materials to be melted.
What is the main purpose of crucible tongs?
Crucible tongs are scissor-like tools, but instead of having two blades, these tools are replaced with two pincers or pieces of metals that concave together, which allow the users to grasp a hot crucible, flasks, evaporating dishes, or even small beakers.
What is the use of clay triangle in laboratory?
Clay triangle A triangular device made of heat-resistent clay. Used to hold crucibles and porcelain dishes heated by a Bunsen burner. Distributes heat evenly over the surface of objects it holds.
What are crucible tongs used for in chemistry?
What does a crucible do to metal?
Crucibles have been used for thousands of years to make alloys and cast metals. To melt metal inside of a crucible, the materials are placed inside and heated until they reach their melting point. You can make a new alloy by melting a combination of materials with other elements inside of the crucible.
What is the dictionary definition of crucible?
A crucible is a severe test or trial or an extremely challenging experience. This figurative sense of crucible is based on the literal meaning of the word: a heat-resistant container used to melt metals.
