Stainless Steel Jewelry
Stainless steel jewelry is strong, durable and rust-resistant. It typically has a silver sheen, but, unlike silver, it will not corrode and it is not susceptible to scratches, dings or dents. Stainless steel can be used to make nearly any type of jewelry, from rings and bracelets to necklaces, watches and earrings. Steel contains carbon, nickel and chromium. In order for steel to be considered stainless, it must contain at least 12 percent chromium. Chromium makes the steel stainless by creating an invisible top layer that prevents oxygen from rusting and otherwise corroding the steel surface. This means that stainless steel jewelry will not rust or tarnish.
Ceramic
A ceramic is an inorganic compound, non-metallic, solid material comprising metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. This article gives an overview of ceramic materials from the point of
view of materials science.
The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous (e.g., glasses). Most often, fired ceramics are either vitrified or semi-vitrified as is the case with
earthenware, stoneware, and porcelain. Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (extensively researched in
ceramic engineering). With such a large range of possible options for the composition/structure of a ceramic (e.g. nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is
vast, and identifiable attributes (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify for the group as a whole. General properties such as high melting temperature, high hardness, poor conductivity, high
moduli of elasticity, chemical resistance and low ductility are the norm, with known exceptions to each of these rules (e.g. piezoelectric ceramics, glass transition temperature, superconductive ceramics, etc.). Many composites,
such as fiberglass and carbon fiber, while containing ceramic materials, are not considered to be part of the ceramic family.
