Despite its popularity and prominence as a collectible, the composition of glass puzzles many. It derives from the fusion of a siliceous material, such as sand or powdered flint, with an alkali, metallic oxide, or salt. The proportion of these primary ingredients and the types of silica and alkali involved determine the transparency or opacity, clarity or distortion of light and color or the lack thereof in the glass.
The first written mention of glass was made by the Roman historian Pliny, who credited the discovery of glass to a group of Phoenician sailors who had landed upon the coast of modern Syria. While lighting a fire, the sailors rested their cooking vessels on blocks of natron (their cargo and a form of alkali). This chance combination of fire, silica, and alkali created true glass, which ran in molten streams from the fire site. Although the tale is appealing, it is more likely that early artisans working with earthenware accidentally discovered the formula
