More generally, copal includes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. [2] Copal that is partly mineralized is known as copaline. It is available in different forms; the hard, amber-like yellow copal is a less expensive version, while the milky-white copal is more expensive.
Bursera glabrifolia is one of two species commonly referred to as copal. Copal is the wood most commonly used by the woodcarvers in Oaxaca , Mexico . The woodcarvers refer to Bursera glabrifolia as "macho" or male copal, which they like less than Bursera bipinnata , which they refer to as "Hembra" or female copal.
Copaline (or copalite), also termed fossil resin or Highgate resin, is a naturally occurring organic substance found as irregular pieces of a pale yellow colour, for example in the London Clay at Highgate Hill.
Copal tree may refer to several tree species: Trees yielding copal resin. Protium copal, a tree endemic to Mexico and Central America; Hymenaea courbaril, also ...
When the C:N ratio is less than circa 25:1, further decomposition causes mineralization by the simultaneous release of inorganic nitrogen as ammonium. When the decomposition of organic matter is complete, the mineralized nitrogen therefrom adds to that already present in the soil and therefore increases the total mineral nitrogen in the soil.
Mineralized tissues are biological tissues that incorporate minerals into soft matrices. Typically these tissues form a protective shield or structural support. [ 1 ] Bone, mollusc shells , deep sea sponge Euplectella species, radiolarians , diatoms , antler bone, tendon , cartilage , tooth enamel and dentin are some examples of mineralized ...
Due to longstanding pushback and controversial health studies surrounding the ingredient, many processed food manufacturers have already shifted away from using Red Dye No. 3, opting instead for ...
