Materials
High quality wine glasses are often made of lead crystal. Lead crystal glasses' advantages are not only primarily aesthetic. One factor of lead crystal is it is generally considered to have a higher index of refraction, thus changing the angle of the light passing through the material. Lead crystal is also rougher than glass on a microscopic level, allowing wine in the glass to breathe more efficiently when swirled in the bowl. They are also heavier. Using lead in the crystal matrix also offers several advantages in the material's workability during production. Wine glasses are generally not coloured or frosted as this would impede the appreciation of its colour. An exception to this rule is the hock glass.

Famous quotes containing the word materials:
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
“Kicking his mother until she let go of his soul
Has given his a healthy appetite: clearly, her role
In the New Order must be
To supply and deliver his raw materials free;”
—W.H. (Wystan Hugh)
“In daily life what distinguishes the master is the using those materials he has, instead of looking about for what are more renowned, or what others have used well.”
—Ralph Waldo Emerson (1803–1882)
