Initially affordable only among the wealthy, glass was used in ancient Rome as containers for oils, perfume, and tablewares. The variety of glass-making techniques reveals the changing tastes and fashions over the centuries. During the 1st century A.D., cast glass was a novel form that was a luxury for the Roman household, but by the end of the century, the innovation of blown glass allowed for less labor-intensive and less expensive production, which meant people of lesser means could afford it. Blown glass became so popular it nearly supplanted ceramic and even bronze wares in the home.
