Crucible tongs are scissors-like tools with a pair of attached arms that curve outward near the ends to form a rounded gripping area that allows users to safely grasp crucibles, flasks, evaporating dishes, or small beakers.[1] They are made of durable metals—stainless steel, brass, or nickel, for example—that can withstand high temperatures.[2]
Crucible tongs are used most often with crucibles, small ceramic or metal vessels used to heat chemicals to temperatures up to 565.56 degree Celsius.[3]
As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly. Therefore, crucible tongs come to play a key role when burning, or doing anything with hot objects. Moreover, some of them also have a special characteristic. For instance, a locking version of crucible tongs can be locked with the edge of a crucible, allow users to be more comfortable and more confidence while moving a very hot crucible from place to place. Hence, they provide more safety for the users.[4]
It is necessary to wear safety goggles, gloves, and proper shoes when using crucible tongs. The scorching objects in a crucible might be spilled off and cause damage to the holder's skin. Since crucible tongs work with the crucible, one must know the safety procedures of the crucible.
