Natural opalite (as opposed to the man-made opalite) shares the same basic chemical properties as opal. It is made of tiny spheres of silicon dioxide , which stack onto each other in a pyramid grid shape.
Main opal producing countries. Opal is a hydrated amorphous form of silica (SiO 2 ·nH 2 O); its water content may range from 3% to 21% by weight, but is usually between 6% and 10%.
A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".

Flubber, also commonly known as slime, is a non-Newtonian fluid, easily made from polyvinyl alcohol–based glues (such as white "school" glue) and borax. It flows under low stresses but breaks under higher stresses and pressures. This combination of fluid-like and solid-like properties makes it a Maxwell fluid.
Austrian opaline glass bowl, 1914. Opaline glass is a style of antique glassware that was produced in Europe, particularly 19th-century France.It was originally made by adding materials such as bone ash to lead-crystal, creating a semi-opaque glass with reddish opalescence.
Alexander Parkes was born at Suffolk Street, Birmingham, the fourth son of James Mears Parkes and his wife Kerenhappuch Childs. Samuel Harrison, described by Sir Josiah Mason as the inventor of the split-ring (or key-ring) and widely credited with the invention of the steel pen, was his great-uncle. [6]
Opalite has been used to describe natural stones before there were widespread synthetics. It has been used to describe material that has simalar characteristics to opal without calling it opal directly. Much the same way the term chalcedony might be used (or misused!) I would not be against this being merged into the opal article, unless there ...
