彩釉玻璃是將無機釉料（又稱油墨），印刷到玻璃表面，然后經(jīng)烘干，鋼化或熱化加工處理，將釉料永久結(jié)于玻璃表面而得到一種耐磨，耐酸堿的裝飾性玻璃產(chǎn)品。

Color glaze glass is an inorganic glaze (also known as ink), which is printed to the surface of glass, and then dried, tempered or heated to process the glaze on the glass surface to get a wear-resistant, acid and alkali decorative glass product.

到了中世紀(jì)，歐洲無數(shù)的天主教教堂都有彩色玻璃窗。然而，直到12世紀(jì)，這些窗戶都相對簡單，規(guī)模小，輪廓由厚鐵架。這是因為羅馬式建筑——一種以厚墻和圓形形式為特征的建筑風(fēng)格——主導(dǎo)了建筑品味。
