Dead skin cells are easily removed by softly rubbing natural pumice stone
block over infected area after bathing or showering. During this process,
blood flow is increased, therefore giving a massaging effects.
Care and health of the feet is important for health of the body. Doctors
highly advise the use of natural pumice stone to diabetics for the
important removal of dead skin cells and the daily care of feet.
How does the pumice form ?
The origin word of Pumice come from Italian and it had constituted weld
for the other languages’ equivalent. Italy has been using the pumice mine
for ages and consumed nearly all its pumice reserve. Italy is not the
single country that consumed its pumice mine. It is possible to give an
example about the pumice mine where it was consumed its reserve in our
country. There has been a pumice mine in Sindelhoyuk village in Kayseri
but as it was finished its reserve, pumice and bims are not produced.
Pumice stone is named different in other languages.

Pumice is a kind of volcanic rock. It has a
glassy shape. As a result of volcanic activities; two kinds of pumice
produced; acidic pumice, basalt pumice. (Scoria, basaltic pumice) The
colour of basalt pumice is dark and its specific weight rather more
according to acidic pumice ( 1,2 - 2 gr/cm3 ) Asidic pumice is the most
widespread and it is used a lot in the world. The colour of this pumice is
light grey colour / dark white because of its own features as silisium,
potassium and sodium. During the formation, because of sudden cold and
sudden gas abandon of structure, it got rather pore shape. Nearly all the
pores don’t have connections each other. Its density is changed between
0,5-1 gr/cm3 . Because of much pore of pumice; its permeability is very
low against to voice and heat. Hardness of pumice is about 5,5 – 6
according to mohs scale and the its SiO2 ratio which formed its structure
is between 60% - 75%. As a result of this ratio; pumice can even abrade
the steel. Pumice doesn’t contain crystal water. pumice stone is
ineffective as chemical.
In the depths of world outer covering, there have been magma pockets which
was formed due to partial melting of basalt. In normal conditions, this
magma sucks all the meterial which may be liquid or gas at very high
pressure. (H2O, CO2, F) With time, the pressure which is upon these magma
pockets, decrease with the effect of ground movement. When the ground
movement occurred, a volcanic explosion starts and these gas erupt from
magma. When the gas disengaged, the stickiness of magma increases very
rapidly and its solidification heat rises. In this way the magma foams,
smashs and it forms the material which is known as pumice. This material
is thrown from the crater with a big gas explosion and it disperses
around.
Pumice is a kind of rock which was not able to find time to be crystallize
because of very sudden cold. When it solidified, the steam which dissolved
in it, is disengaged suddenly and it forms pore structure with eruption.
When these conditions formed all kinds of lava may become pumice.
Obsidien, peks-tayn and perlite, are acceptable as own sort of pumice. The
pumice is mostly compared with perlite from volcanic rock varieties like
obsidien, peks-tayn and perlite. However pore shape of pumice, as it isn’t
contain cyrstal water and as any process was not done, as it is used
naturally, it provides much advantage to pumice. The natural lightness of
pumice provides very big easiness to the pumice purification process from
other impurities. This process can only be made by using the water because
the pumice can remain over the water. For this reason it doesn't pollute
the environment and it doesn't waste the energy sources in order to
transform into other products.
Pumice in History
B.C.(Before Christ) in first century at architecture summary which is
belong to Vitruvio the pumice is mentioned. Vitruvio defines it as
"lighter than water" therefore he defines it as “swimmer" Also he explains
that "it does not suck the water" and " it is hygienic" as well. The
pumice stone was used usually at the construction of thermal bath and
temple in the time of Romans. Some of these works of art can still be
seen. The clearest examples which belong to these eras are; Roman
Pantheonu and Hagia Soffia (or Ayia Sophia) church in Istanbul. It was
started to use in Germany in Rhinenland city during 18 th century. In the
vicinity of Europe any interest wasn’t showed to pumice until the near
period. The pumice stone was started to use in California as a contruction
material in the middle of 18 th century in U.S.A. Within last 30 years; by
technological development and by increasing of environment sensitivity,
have been getting its using widespread.
Pumice using in Textile Sector
The physical and chemical features of pumice (Na2O - K2O) are
completely convenient to do stonewash for products at textile industry. By
the development at washing techniques, the pumice stone was started to use
to wash lighter fabrics as well. Also the bigger calibrated ponza stones
were started to use at new generation washing machines.
The pumice which is used in this sector is the asidic one and its colour
is white. It doesn't form stain at the product and it doesn't necessitate
any cleaning. This situation doesn't cause any extra increase to the cost
of textile product. However, the pumice which will be used must have been
rounded and it must have been decomposed painstaking from all other
impurities. Also the differences of the fabric which will be washed and
because of the diversities of washing machines; the pumice must have been
calibrated with different dimensions.
At the textile sector in order to do a well abrasion without giving damage
to the product, we recommend our pumice which have no impurities, with
high quality and painstaking workmanship was applied.
Pumice using at Constructions
The type of the pumice stone which is being utilized at constructions,
named as bims and was passed from German to our language. It has perfect
physical and mechanics features. The pumice is used usally in all the
places where the perlite is used. The energy and investment that are used
at perlite, as is not necessary at pumice; because of the need to protect
energy and as it is durable against to the earthquake, the using of pumice
products are continue to increase with a growing fast. Because of the
distressing earthquakes that were occurred in our country ; the
construction sector started to give importance to these products.
The pumice has as much density as the normal sand's and gravel 's 1/3 -
2/3 . The same situation is seen at the concretes as well which was made
with pumice. At the constructions the pumice concrete provides economy,
from the time and workmanship because of to be lighter than normal
concrete. (Unit volume weight 800 - 900 kg / m3 ) Also it is possible to
economize from the iron approximately 20 %, as the pumice will have
decreased the burden which is added to the subbase.
Instead of sand-gravel mortar, using pumice stone mortar, because of
lightness of mortar causes less loading to the mechanical strength, To use
light weight products as block for down concrete and as wall component,
causes less concrete needs and the time and workmanship advantages which
was provided from to use orderly component causes decreasing at
construction costs. Also at the walls which was constructed with the sort
of these blocks; directly gypsum, ceramic and similar coatings are able to
be applied. In the event of plaster applying, cracking and blistering
aren’t occurred at the plaster at next years.
Heat permeability coefficient of pumice ( 0.33 - 0.80 kcal / mh 0C ) is
plus more 5 – 7 times than normal concrete. Because of its this feature,
it provides considerable heat and energy economizing. Because of the
pumice’s pore shape, heat insulation of construction components which were
produced from pumice, too much more than the other construction components
which were produced from the other materials. The constructions which were
built by using the pumice productions, as it provides high heat
insulation, it decreases considerably the expenses of heating and cooling.
Also its perfection that shows for the voice insulation is offered to the
constructions as an extra convenience.
The block for down concrete is a nother kind of light weight construction
component that was produced from pumice and it is used at story concrete.
Also the pumice stone is used at construction as subbase filling material
and as roof insulation material as well.

the fire. |
| Because of its high thermal durable. |
| Because of its maximum voice insulation. |
| It sticks well on the plaster. Because of
easy workmanship. |
| It is durable against to the getting
iced. |
Pumice using at Agriculture
The volcanic soils with their natural structure, the decayed plants, with
the supplement nourishment that were provided by animal and human life; it
provides very convenient milieu in order to grow plant. 85 % pore shape of
pumice stone causes to show light density features. Even the smallest
pumice has a lot of both large and small pores. The soil’s situation
becomes porer and it airs. Also it is used in order to improve features of
soil and hinder to become lump of artificial fertilizer. The pumice is
used as soil at greenhouses, in the region where sour orange grows, at the
orchard, at the grass field and in all the agriculture regions. Their
applying results are perfect.

The advantages at agriculture
that were provided by the pumice
|
| |
| It provides perfect airing. |
| You are able to use it repeatedly. |
| It doesn’t get lump and shrink with time.
|
| The nourishment adjustment's control is
easy. |
| It doesn’t shelter the harmful elements
as fungus and insect. |
| It is watered easily. |
| It doesn’t decay. |
| It doesn’t produce bad odors. |
| It is pH neutral. (6-7) |
Pumice using at Building Restoration
Today, a lot of developped countries make the cleanliness by using the
pumice stone, instead of sand at sandblasting method for clean the
historical building’s dirtied fronts. The pumice stone gives opportunity
to do the cleaning without giving damage to the surface of building,
because of the pumice’s soft abrading feature.
Pumice using for filtration
The pure pumice stone is able to be used for filtration of drinking water.
The pumice doesn’t contain any elements which may be threat for human
health. While the pumice is being used at two layer filter; it is usually
used for primary refining because of its lightness. The other layer below,
strains the small material which was not able to be caught by pumice.
Pumice using at Cosmetic
The pumice stone is raw material of foot assist. The products that were
produced from pumice stone are widespreadly used firstly at soap, in
toothpaste, in tooth powder and in creams.
Pumice using at Glass Sector
The pumice is used again as a material for television tube correction,
glass polishing, cut glass completing.
Pumice using at Electronic Sector
Because of its soft abrading feature, the pumice products are prefered at
circuit packets cleaning.
Pumice using at Paint Sector
The pumice products are used at voice insulating wall paints, primer paste
correction for motifed paint.
