Crucibles and their lids can come in high form and low form shapes and in various sizes, but rather small 10 to 15 ml size porcelain crucibles are commonly used for gravimetric chemical analysis. These smaller crucibles and their covers made of porcelain are quite cheap when sold in large quantities to laboratories, and the crucibles are ...
Crucible An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [ a ] and sometimes to their melting point . Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.
A Gooch crucible, named after Frank Austin Gooch, [1] is a filtration device for laboratory use (and was also called a Gooch filter [2]). It is convenient for collecting a precipitate directly within the vessel in which it is to be dried, possibly ashed , and finally weighed in gravimetric analysis .
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.

Wet chemistry commonly uses laboratory glassware such as beakers and graduated cylinders to prevent materials from being contaminated or interfered with by unintended sources. [3] Gasoline, Bunsen burners , and crucibles may also be used to evaporate and isolate substances in their dry forms.
In 2006 researchers at University College London and Cardiff University discovered that potters in the Hesse region of Germany since the late Middle Ages had used mullite in the manufacture of a type of crucible (known as Hessian crucibles), that were renowned for enabling alchemists to heat their crucibles to very high temperatures.
The crucibles were made by firing kaolinitic clay at temperatures greater than 1100°C, forming mullite. Mullite is an aluminum silicate only described in the 20th century and is responsible for the excellent properties of the Hessian crucible. [1] [2] Main production centre of the Hessian crucibles was the village of Großalmerode.
