Enamel pearls can be composed of different dental tissues (enamel, dentin, etc.) and can thus be classified based on this composition. Enamel-dentin pearls make up the largest proportion pearls and consist of a core of tubular dentin surrounded by enamel. Large enamel-dentin pearls may contain pulp within and are termed enamel-dentin-pulp ...
The chambered nautilus (Nautilus pompilius), also called the pearly nautilus, is the best-known species of nautilus. The shell, when cut away, reveals a lining of lustrous nacre and displays a nearly perfect equiangular spiral, although it is not a golden spiral. The shell exhibits countershading, being light on the bottom and dark on top. This ...
In animal tooth development, the inner enamel epithelium, also known as the internal enamel epithelium, is a layer of columnar cells located on the rim nearest the dental papilla of the enamel organ in a developing tooth. This layer is first seen during the cap stage, in which these inner enamel epithelium cells are pre-ameloblast cells.
The veneers used are primarily woods, but may include bone, ivory, turtle-shell (conventionally called "tortoiseshell"), mother-of-pearl, pewter, brass or fine metals.. Marquetry using colored straw was a specialty of some European spa resorts from the end of the 18th ce

Champlevé is an enamelling technique in the decorative arts, or an object made by that process, in which troughs or cells are carved, etched, die struck, or cast into the surface of a metal object, and filled with vitreous enamel.
Fast dry enamel – Can dry within 10–15 minutes of application. Ideal for refrigerators, counters, and other industrial finishes. [7] High-temp enamel – May be used for engines, brake calipers, exhaust pipe and BBQs. Enamel paint is also used on wood to make it resistant to the elements via the waterproofing and rotproofing properties of ...
As the cells of the reduced enamel epithelium degenerate, the tooth is revealed progressively with its eruption into the mouth. The degeneration of reduced enamel epithelium also mediates the initial epithelial attachment to the tooth, which is called the junctional epithelium. The reduced enamel epithelium consist of: Inner enamel epithelium
Romanesque champlevé enamel was applied to a cheap copper or copper alloy form, which was a great advantage, but for some pieces the prestige of precious metal was desired, and a small number of nielloed silver pieces from c. 1175–1200 adopt the ornamental vocabulary developed in Limoges enamel.
