DIY pipeclay triangle

A very simple pipeclay triangle can be made by inserting three thick metal wires through three ceramic tubes and twisting the wire ends using pliers. Alumina tubes, found in various machinery or electric machines, can be used, as they handle direct flame very well.

As a last resort, you can also make a simple triangle with “tails” at its tips from a steel of SS wire, then wrap the inner triangle with asbestos or ceramic fiber tape or sheets.

What Is a Pipestem Triangle Used For?

A pipestem triangle is used to support crucibles or other lab dishes that are being heated on a burner or other heat source. The supported items are placed on the iron wire covering of the pipestem and heated directly. The triangle decreases oxidation and prevent the wires from drooping.

Also known as pipeclay triangles, pipestem triangles are made using wires threaded into an equilateral triangle with ceramic tubes on each side and supported by a support ring. They are normally made from porcelain pipes and galvanized steel. Their dimensions vary widely although the most common lengths are between 1.5 and 2.5 inches long.
