A
Short History of Plaster
Plaster has been in use for
thousands of years. It can be seen in pyramids and
temples, churches and Roman buildings. The most ancient
plaster discovered was used circa 9000 B.C. in the region
of Mesopotamia. In 7500 B.C., Jordanians used a
mixture of lime and limestone.
The Greeks also
used gypsum, in ancient Egypt; the Egyptians used plaster mainly as a
surface for their decorations. There are lots of examples of
Roman use, particularly in the remnants of the city of Pompeii.
They used a hard, fine plaster on their walls and ceilings,
with wonderful relief
ornamentation.
Plaster has been used in art, and in the
manufacture of homes and countless buildings throughout
the ages. In Medieval and revival times, gesso, which is
plaster of Paris mixed with glue, was used to grant the
ground for tempera and oil painting.
Medieval Europeans had a production system
known as wattle-and-daub; wooden frames filled with
plaster. Even the Native Americans used clay to form a
sort of plaster that filled holes within a framework of
small branches woven like basketwork between supporting
poles, resembling the wattle-and-daub
method.
It is a resourceful medium that stands the
test of time. Even today, buildings that are hundreds of
years old still have plaster in outstanding
condition.
In the nineteen hundreds plaster was
mostly replaced by gypsum board (also called sheetrock or
drywall), not because of better quality, but because it
was less labor intensive and cost less. Plaster has been
replaced, and in some cases almost forgotten, but its
quality cannot be matched or outdone by the materials
that are being used in its
place.
