A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring.
It is used for holding a test tube in place [2] when the tube is hot or should not be touched. [3] For example, a test tube holder can be used to hold a test tube while it is being heated.

A myth contained in the classical Jewish text Pirkei Avot states that the first pair of tongs was created by God right before God rested on the Seventh ...

When they are specifically used to occlude an artery to forestall bleeding, they are called hemostats. Another form of locking forceps is the needle holder, used to guide a suturing needle through tissue. Many locking forceps use finger rings/loops to facilitate handling (see illustration, below, of Kelly forceps).
It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source. [14] This type of tube is used in the sodium fusion test. Ignition tubes are often difficult to clean due to the small bore. When used to heat substances strongly, some char may stick to the walls as well ...
