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.
A fourth term, loam, is used to describe equal properties of sand, silt, and clay in a soil sample, and lends to the naming of even more classifications, e.g. "clay loam" or "silt loam". Determining soil texture is often aided with the use of a soil texture triangle plot. [5] An example of a soil triangle is found on the right side of the page.
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
Soil texture triangle. Soil texture influences the soil chemistry pertaining to the soil's ability to maintain its structure, the restriction of water flow and the contents of the particles in the soil. Soil texture considers all particle types and a soil texture triangle is a chart that can be used to calculate the percentages of each particle ...

Composite liners are used in municipal solid waste (MSW) landfills to reduce water pollution. A composite liner is made of a geomembrane along with a geosynthetic clay liner. Composite-liner systems are better at reducing leachate migration into the subsoil than either a clay liner or a single geomembrane layer. [9]
Constructed wetlands can be used to treat raw sewage, storm water, agricultural and industrial effluent. Constructed wetlands mimic the functions of natural wetlands to capture stormwater, reduce nutrient loads, and create diverse wildlife habitat. Constructed wetlands are used for wastewater treatment or for greywater treatment. [6]
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.
