WHAT IS THE MEERSCHAUM ?
Meerschaum, Mg2Si3O8
. 2H2O, is a clay mineral which belongs to the Sepiolite is currently used
in more than 100 different ways in industry. Several deposits of
meerschaum have been reported in Turkey. The deposits in Eskisehir
province are considered to be most important commercially. They occur in
conglomerates as nodules and in stratified detrital limestone. The
impurities present in Eskisehir’s meerschaum are: chert, opalline quartz,
sparry calcite, dolomite and clay (probably Mg-smectite and illite) as
fracture infills. The deposits were formed in the Central Anotolia basin
during, Oligo-Miocene time. Most authors have attributed the origin of
meerschaum as a product of the hydrothermal alteration of magnesite and
serpentinite. Traditional methods of minig meerschaum in Eskisehir have
proven
to be most economic. However, the relative shallow depth of the
water table represents one major problem in some areas.
The Eskisehir
meerschaum has been used for nearly 200 years in making pipes and other
articles for smokers, and small quantities have been used for other
purposes, such as decoration, bracelet, necklace, removing stains, and
also as thermal insulator material.
In Turkey, the most common usage of
meerschaum is pipemaking, because of its unique properties, such as
sorption, chemical composition, white color, good porosity, low specific
gravity, catalytic properties and thixotropy. Meerschaum pipes have been
exported primarily to the USA, Australia, Canada, England, Germany,
Norway, Denmark and other Europen countries.
