What is a crucible how is it used?
A crucible is a piece of laboratory equipment used to heat chemical compounds to very high temperatures or to melt metal. It’s a little container full of violent reactions.
Where are crucibles used?
Crucibles are used in fuel–fired furnaces, in electric resistance furnaces, in induction furnaces or simply to transfer molten metal. They come with or without pouring spouts and in a wide variety of traditional and specialized shapes.
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
What is the use of crucible in laboratory apparatus?
A lab crucible is a type of laboratory glassware used to burn, melt or mix solid chemical compounds over a burner. It can hold all kinds of substances, materials and fluids. It is also used in quantitative gravimetric chemical analysis.
What are the two meanings of crucible?
1: a vessel of a very refractory (see refractory entry 1 sense 3) material (such as porcelain) used for melting and calcining a substance that requires a high degree of heat. 2: a severe test He’s ready to face the crucible of the Olympics.
What is the crucible a metaphor for?
In his 1953 play The Crucible, playwright Arthur Miller employs a fictionalized account of Massachusetts Bay colonists accused of witchcraft in 1692 as a metaphor for government persecution of suspected communists during the mid-20th century.
Can you use steel as a crucible?
Yes if it is thick steel and not just like a coffee can. It will degrade over time but at aluminum temperatures it should last more than long enough for multiple uses.
What do you use for a crucible?
crucible needs to be ceramic, to melt steel cans you have to raise the temp as high as the melting point of steel so any ferrous metal crucible will melt as well. Steel or cast iron works well for aluminum lead copper or gold though. Chairman Mao found out backyard steel don’t work so well.
Why do we use crucible?
Crucible is used in the laboratory to contain chemical compounds when heated to extremely high temperatures. Crucibles are available in several sizes and typically come with a correspondingly-sized lid.
What are the different types of crucible?
Crucibles – Porcelain, Platinum, PTFE, Stainless Steel, Nickel, Carbon Steel, Zirconium and Vitreous Carbon.
Why is it called the Crucible?

What is the function of Crucible Tong?
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 are the uses of laboratory tongs?
Laboratory tongs are large pincers for grasping and lifting vessels of heat -resistant material used in high temperature chemical reactions. Tongs differ in shape are designed to pick up laboratory items including, hot evaporating dishes, beakers, crucibles, and other laboratory apparatuses.
Why did we use porcelain crucible?
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.
