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.
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
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]
Wire gauze was also used in safety lamps containing a flame in coal mines and environments where flammable gases may build up; the gauze prevents the flame from igniting gas outside the lamp, causing an explosion. Some wire gauze is made with a ceramic centre. [4]
A laboratory tripod is a three-legged platform used to support flasks and beakers. Tripods are usually made of stainless steel or aluminium and made light-weight for efficient portability within the lab.
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.
Crucible tongs are used most often with crucibles, small ceramic or metal vessels used to heat chemicals to temperatures up to 565.56 degree Celsius. [3] As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly. Therefore, crucible tongs come to play a key role when burning, or doing ...
Lute (from Latin Lutum, meaning mud, clay etc.) [1] was a substance used to seal and affix apparatus employed in chemistry and alchemy, and to protect component vessels against heat damage by fire; it was also used to line furnaces. Lutation was thus the act of "cementing vessels with lute".
