The Pipeclay Triangle is a crucible for burning.
It is twisted with iron wire and covered with porcelain tubes, of different sizes. It can be used to support a burning crucible or a small evaporation pan for heating. When the crucible is placed, the bottom of the crucible should be placed on one of the three porcelain tubes horizontally and diagonally.
A triangular support made of wound heat – resistant ceramic tubes and iron wire, used to support a crucible for heating and preventing cracking.
The Pipeclay Triangle can withstand high temperatures because it is encased in heat-resistant ceramic tubes, and it can withstand weight because the hollow tubes are threaded with iron wire. When an object needs intense heat from a Bunsen burner, a mud triangle is usually placed on an iron ring as support for the object. Or in experiments that require an alcohol lamp to heat a crucible.
