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.
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.
White pipe clay, white-firing clay of the sort that is used to fashion smoking pipes Pipeclay triangle, a piece of laboratory equipment, typically made from this material; Catlinite or Pipestone, found in Sioux Quartzite deposits in the upper midwestern and southwestern United States, that is used to fashion smoking pipes
A 5-inch (125 mm) square of wire gauze with ceramic center Using wire gauze with an alcohol burner. Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting.
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
Iron rings used in a laboratory. An iron ring or ring clamp is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. [1] In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder. [2]
Stourbridge clay mixed with water could withstand the highest heat of any lute. [7] Hard cement was also commonly used to join glass vessels and fix cracks; it was composed of resin, beeswax and either brick dust or "bole earth", or red ochre or venetian red. Soft cement, made of yellow wax, turpentine and venetian red, was also used for repair ...
Clay chemistry is an applied subdiscipline of chemistry which studies the chemical structures, properties and reactions of or involving clays and clay minerals.It is a multidisciplinary field, involving concepts and knowledge from inorganic and structural chemistry, physical chemistry, materials chemistry, analytical chemistry, organic chemistry, mineralogy, geology and others.
