一種非結晶的無機物質,以熔合矽石(二氧化矽)及鹼性氧化物而成。一般來說應為透明,但常常呈半透明或不透明。其性質之特色為在常溫下材質堅硬,高溫下則具可塑性,另外能抗風化及不受大部分化學物質侵蝕(氫氟酸除外)。兼具實用與裝飾用途,能塑成多種形狀,可上色或另加修飾。玻璃最早為釉料,見於西元前約三千五百年的美索不達米亞區域(Mesopotamia),而首個完全由玻璃製成的物件記載於西元前約2500年。 Een amorfe, anorganische substantie die wordt gemaakt door silica (siliciumdioxide) te fuseren met een basisoxide, meestal transparant maar vaak ook doorschijnend of ondoorschijnend. Kenmerkende eigenschappen zijn de hardheid en stijfheid bij normale temperaturen, de plastische eigenschappen bij verhoogde temperaturen en de weersbestendigheid en bestendigheid tegen de meeste chemische stoffen, behalve waterstoffluoride. Het wordt gebruikt voor zowel gebruiksdoeleinden als decoratieve doeleinden, en kan worden gemaakt in diverse vormen, gekleurd en gedecoreerd. Glas is ontstaan als glazuur in Mesopotamië in ongeveer 3500 v. Chr. De eerste voorwerpen die geheel van glas zijn vervaardigd, dateren van ongeveer 2500 v. Chr. Sustancia amorfa inorgánica fabricada por fusión de sílice (dióxido de silicio) con un óxido básico; generalmente transparente, pero a menudo translúcido u opaco. Sus propiedades características son la dureza y rigidez a temperatura ordinaria, su capacidad para ser trabajada plásticamente a elevadas temperaturas y su resistencia a la acción atmosférica y a la mayoría de los productos químicos, excepto al ácido fluorhídrico. Utilizada para propósitos utilitarios y decorativos, puede dársele diferentes formas, colores o decoraciones. El vidrio se originó como vidriado en Mesopotamia aproximadamente en 3500 a.C., y los primeros objetos realizados enteramente de vidrio datan de aproximadamente 2500 a.C. An amorphous, inorganic substance made by fusing silica (silicon dioxide) with a basic oxide; generally transparent but often translucent or opaque. Its characteristic properties are its hardness and rigidity at ordinary temperatures, its capacity for plastic working at elevated temperatures, and its resistance to weathering and to most chemicals except hydrofluoric acid. Used for both utilitarian and decorative purposes, it can be formed into various shapes, colored or decorated. Glass originated as a glaze in Mesopotamia in about 3500 BCE and the first objects made wholly of glass date to about 2500 BCE.
