Final answer:
Stained glass is a form of art that uses metallic oxides to create colors in the glass. The colors are ingrained in the glass as it cools, resulting in a beautiful display of colors when light passes through. The perception of stained glass changes with the lighting conditions.
Step-by-step explanation:
Stained glass is a form of art that uses different metallic oxides to produce colors in glass. The colors are created by mixing specific oxides, such as copper(II) oxide for turquoise, manganese dioxide for purple, cadmium sulfide for red, cobalt oxide for blue, and Iron(II) oxide and chromium(III) oxide for green. These oxides are added to the molten glass, and when the glass cools, the colors become ingrained in the glass. The beauty of stained glass is not only due to the coloring, but also how light passes through the glass, creating different perceptions of color depending on the lighting conditions.
