Natural stones in ancient buildings in Iran
Natural Stones & Ancient Buildings
The use of natural stones in Iran has a long history. In the ancient time, natural stones have been used to form civilization in Iran. The remaining buildings and works from that time can speak for itself. Among all, Persepolis, Pasargadae and many other Islamic buildings can be named.
There are totally billion tons of natural stone resources in the world including Granite, Marble, Onyx and Travertine. 4.7 Million tons of resources are in Iran. That makes Iran the fourth country in the world for supplying natural stones. However, in terms of color variety and quality, Iran is ranked the first in the world.
Many decorative objects made out of Marble and Onyx used as dishes and jewelry are now exhibited in museums of Iran and other countries. Discoveries also show that, these rocks were used as interior decoration in buildings. Discovery, extraction, transportation, cutting, polishing and using natural stones which were performed in traditional ways, has been transformed profoundly in recent decades. The most important part of this transformation is using modern methods in production and use of these resources. Using Non-explosive extraction methods and deploying hard-cutting machines are the most important changes in Iran’s rock industry, which have taken place in the recent decade and have expanded production and consumption of natural stones.
History of Using Natural Stones
Application of rocks in buildings dates from 12 thousand years ago, and discovering ancient structures like the Egyptian pyramids and structures in Iran and Rome has stunned many people, considering the technology at that time.
Application of stones started with using large blocks, but as the technology went on, weight of stones decreased and they paid more attention to color, polishability, texture and strength of the stones. Nowadays stone plates that are beautiful, colorful, polished and low in thickness are used more frequently.
Pasargadae (Tomb of Cyrus the Great)
The stones that are used in Pasargadae and Persepolis include white limestone (similar to Onyx), grey stonesimilar to Granite in hardness and sometimes black Marble which is very fragile. The black stone used in Pasargadae after 25 centuries has become very fragile and is easily broken into pieces, but the other 2 types are very durable.
Two main kinds of stones are used in the structure, light-colored and grey stones. These stones were carried to desired places in blocks as heavy as 30-40 tones, and the weight of only one of the columns is 17 tones.
