in early 1993 by the National Center for Supercomputing Applications (NCSA)
at the University of Illinois at Urbana-Champaign, Mosaic is available

Mosaics
Mosaics, surface decorations, composed of variously colored small pieces of glass, stone, ceramics, or other materials.
Materials and Techniques
In ancient times mosaics
were a form of floor decoration made of small pebbles and later of cut
or shaped pieces of marble, hard stone, glass, terra-cotta, mother-of-pearl,
and enamel. Pieces, in the form of small
cubes,
are called tesserae or tesselae, and are embedded in plaster, cement, or
putty using various techinques.
Damaged mosaics in Istanbul
have provided
information
on techniques. Walls to be covered with mosaics received three coats of
plaster made up of combinations of lime, sand, brick dust, straw, and marble
dust. The plastered wall was then painted in detail in fresco and immediately
set with colored cubes to match the painted surface.
To make tesserae, thin slabs of marble or colored stone were cut into strips, which then were cut or broken into cubes. Molten glass was tinted with metal oxides in a wide range of colors and then broken into strips and cubes after solidifying. Gold and silver cubes were produced by gilding glass slabs of pale shades with gold or silver leaf. The cubes were set into the painted surface one at a time, often resulting in deliberate irregularity of the surface.
Pre-christian Mosaics
In the 4th and 3rd millennia BC, Mesopotamia developed a type of mosaic composed of slender cones of baked clay with some base ends painted red, black, and white. These were embedded in mud brick walls to create a decorative protective coating in geometric patterns.
In Crete and on the Greek
mainland during the Bronze Age (1600-1000 BC),
water-worn
pebbles were used to decorate floors, sometimes in subtle, multicolored
designs. Before the end of the 3rd century BC, pebbles were replaced in
large part with tesserae cut from stone and sometimes from glass, allowing
artisans to create more detailed designs. Early mosaics from Pompeii show
the introduction of Hellenistic mosaics in Italy.
In the Renaissance (14th century to 17th century), mosaic workshops were active in Venice and Rome, where the technique imitated that of illusionistic painting on a gigantic scale. A revival occurred during the 19th century, when mosaics workshops were established in Italy, France, England, and Russia.
Pre-Columbian Mosaics
The Native Americans of Central America independently developed a mosaic technique. Turquoise, a popular material, was cut into small pieces set with vegetable resin onto harder surfaces such as bone and pottery.
