Shanxi black is mainly composed of plate-like plagioclase, which is
composed of twin crystals. It accounts for 55-60%. The pyroxene is
20-30%, and the amphibole and secondary amphibole are about 5%, and
also contain trace minerals such as biotite, chlorite, quartz and
potash feldspar.
Shanxi black stone is now widely used in architectural decoration.
The Shanxi black stone can be used as a tombstone. The nameplate,
the Shanxi black of litchi surface can be used for outdoor shops.
The Shanxi black stone of the mushroom surface can be used as the
roadside stone. All the places where the building needs stone can
be used in the Shanxi black stone. Because of the Shanxi black
stone fire caused the appearance of dyeing Shanxi black now, dyeing
Shanxi black and dyed still have a certain difference, the two
sides have the advantages:
Dyeing Shanxi black stone has a certain price advantage. Now, the
cost of dyeing Shanxi black on the market is much cheaper than that
of finished Shanxi black. And the quality of stone is also good,
and the quality is very good. So dyeing Shanxi black has a certain
cost performance advantage.
Partial dyeing of Shanxi black will lead to uneven color. Unlike
Shanxi black itself, the natural stone color, dyed Shanxi black
because the color is later artificial color, so in the color will
be uneven. It is easy for workers who are not skilled in working to
make the color uneven. The edges of the plates are stained with
dye, so that they are different from the real Shanxi black. But if
a good worker, these are not matters. In this case, the finished
products are not seen by ordinary people.
Dyeing Shanxi black every year needs protection, and later cost is
higher than that. Dyed Shanxi black color is later artificial, so
in the long term use must be regular protection, discoloration is
easy to appear, so this makes dyed Shanxi black later cost
increase. The most important thing is that dyes containing
chemicals are harmful to human body, so indoors are not
recommended. Shanxi black dyeing and natural Shanxi is still some
gaps.
