A view of the periodic table of elements differentiating metals, metalloids and nonmetals – “The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable and ductile … Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile … metalloids are intermediate in their properties … more like the nonmetals, but under certain circumstances, several of them can be made to conduct electricity. These semiconductors are extremely important in computers and other electronic devices.”

A site that goes into the history, invention and making of glass. “The very first glass known to stone age people which was used for making weapons and decorative objects, was obsidian, black volcanic glass. The earliest known man made glass are date back to around 3500BC, with finds in Egypt and Eastern Mesopotamia. Discovery of glassblowing around 1st century BC was a major breakthrough in glass making.”
From the Corning Museum of Glass. “Thousands of different chemical compositions can be made into glass. Different formulas affect the mechanical, electrical, chemical, optical, and thermal properties of the glasses that are produced. There is no single chemical composition that characterizes all glass. Typical glass contains formers, fluxes, and stabilizers.” Also on this site, see the Glass Dictionary, Museum Publications and more.

Precompressed Hardwood for easy bending, even in the cold condition. Finished components may be bent in more than one plane and in small radii of curve.
A variety of Cork Products from a company that’s been around for 150 years. Also see their Cork Store
Standard and custom-made industrial & consumer cork products.
Information and resources from APCOR, the Portuguese Cork Association (Associação Portuguesa de Cortiça), which ”…represents, promotes, divulges and carries out research in the Portuguese cork industry”. Portugal produces more cork than any other country in the world. Cork production is a sustainable process, as the bark is stripped to harvest the cork while the tree continues to live and grow.
