Julian tongs are made from a single piece of metal that is bent in half and has a sliding bracket to adjust the distance between the jaws.Crucible holders may have other shapes that are suited to specific applications (melting precious metals, for example). They range in size from one millimeter to multi-liter. In addition, some crucible tongs can be securely attached to the crucible with a locking device for added security. Beakers usually have a flat bottoms and a lip around the top. Because crucibles are typically heated to very high temperatures, the tongs must also be able to tolerate high heat. The arms themselves may also be curved to accommodate the shape of crucibles, flasks, beakers, or other glassware items.

Crucible tongs are typically made of metal and have two curved and concave pincers.Typically used to hold beakers that have been heated, the ends of the jaws may also be wrapped or coated with an insulated material.
