History of Stone in Human Civilization

The history of stone use in human civilization dates back approximately 2.5 million years. During the Old Stone Age (Paleolithic), our ancestors first shaped flint and basalt stones by chipping them to create simple tools such as hand axes, knives, and spearheads. This tool-making revolution set humans apart from other primates.

In the New Stone Age (Neolithic), with the emergence of the first villages, stone went beyond tools and became a primary building material. The stone walls of Jericho, the towers of Çatalhöyük, and the stone circles of Stonehenge in England all demonstrate humanity's growing understanding of the strength and durability of stone.

The great ancient civilizations each brought stone to new heights in their own way:

• The Egyptians quarried and transported massive blocks of granite and limestone to build the Pyramids of Giza, which still stand after 4,500 years.
• Mesopotamians used black and white stones to create inscriptions and epic reliefs, such as the Code of Hammurabi stele.
• The Achaemenid Persians at Persepolis and Naqsh-e Rostam carved stone columns, staircases, and reliefs with unparalleled elegance, narrating the glory and cultural diversity of the Persian Empire.
• The Greeks and Romans built temples, theaters, and aqueducts from marble and travertine, forever shaping the foundations of Western architecture.

During the Middle Ages, stone churches and castles symbolized the power of God and feudal lords. In the Renaissance, stone was transformed into lifelike sculptures by the hands of artists such as Michelangelo.

The Industrial Revolution mechanized stone extraction and cutting, bringing stone out of palaces and onto sidewalks and the facades of ordinary buildings. Today, from decorative stones used in flooring and facades to industrial stones employed in road construction, concrete, and even electronic chips, the history of stone in human civilization continues to unfold. It is a story that began with a stone axe in the hands of early humans and has since found its way into the heart of modern technology.

Types of stones and their properties

1. Igneous Rocks

• Granite: Hard, resistant to abrasion and acids, with coarse crystalline grains. Suitable for flooring, stairs, and interior and exterior facades.
• Basalt: Very hard and heavy, dark-colored (gray to black), with high compressive strength. Suitable for street paving, railways, and road surfaces.
• Pumice: Lightweight, porous, rough, and floats on water. Suitable for skin exfoliation and manufacturing lightweight building blocks.
• Dolerite: Finer-grained than basalt, hard, and dark. Suitable for sand, gravel, and road construction materials.

2. Sedimentary Rocks

• Limestone: Relatively soft, reacts with acid, cream or gray in color. Suitable for producing cement and lime, as well as for interior facades.
• Travertine: Porous, layered, lightweight, and heat-resistant. Suitable for building facades, courtyard flooring, and bathrooms.
• Sandstone: Rough, composed of cemented sand grains, with moderate strength. Suitable for courtyard paving and non-load-bearing walls.
• Quartzite: Very hard, resistant to acid and abrasion, usually white or gray with a glassy luster. Suitable for staircases, facades, and kitchen countertops.

3. Metamorphic Rocks

• Marble (Marble - crystalline): Crystalline, takes a high polish, available in a wide range of colors (white, green, pink, black), soft and sensitive to acid. Suitable for sculpture, luxury flooring, and countertops.
• Marble (Marble - intermediate type - "Marmerit"): Between marble and limestone in composition, takes a good polish, more resistant to staining than crystalline marble. Suitable for stairs, flooring, and hotel lobbies.
• Slate: Dark, with parallel layers, completely impermeable. Suitable for false ceilings, terrace flooring, blackboards, and garden paving.
• Hornfels (Metamorphosed Shale): Very hard, fine-grained, shiny, resistant to heat and acid. Suitable for industrial flooring, laboratories, and roofing.

Uses of stones in human life

1: Tools and Survival (Early Historical Stage)

Scenario: A piece of granite, broken off from a mountain by weathering, is found by early humans near a riverbank.

How it was used: Using skilled strikes, they shaped it into a simple hand axe or grinding stone (for cracking nuts).

Reason for choice: Due to its hardness and high density, granite is ideal for pounding, cutting, and grinding.

2: Monumental Architecture (Ancient and Classical Civilizations)

Scenario: Now, a larger block of the same granite is quarried by workers using wedges and picks.

How it was used: After carving and partial polishing, this block is used as a palace column, a temple foundation, ziggurat steps, or a pharaoh's statue.

Reason for choice: Exceptional resistance to pressure, weathering, and time; a symbol of power and eternity.

3: Modern Construction Material (Industrial Stage)

Scenario: Today, quarried granite is cut into thin slabs using diamond wire saws.

How it is used:

• Flooring and facades of luxury buildings and metro stations (due to resistance to foot traffic).
• Kitchen countertops (resistant to heat and scratches).
• Public staircase steps.

Reason for choice: Natural beauty, color variety, ability to take a polish, and extremely high durability.

4: Aggregate in Concrete and Infrastructure (Hidden but Massive Use)

Scenario: Waste and fragments of the same granite that are unsuitable for slabs are sent to a stone crusher.

How it is used: These pieces are crushed down to sand and gravel. Then:

• The sand and gravel are mixed with cement to produce concrete – the material that forms the basis of dams, bridges, tunnels, and skyscrapers.
• Fine gravel is used as ballast (foundation material) beneath railway tracks to hold them in place.

Reason for choice: Crushed stone is cheap, readily available, and highly resistant to pressure.

5: Source of Raw Materials for Other Industries (Chemical and Technological Use)

Interesting fact: Granite is composed of various minerals (quartz, feldspar, mica). Each has its own separate application:

• Quartz (silica sand): Melted down and turned into glass, drinking glasses, eyeglass lenses, and fiber optics.
• Feldspar: Used in the production of ceramics, tiles, and pottery glazes.
• Mica: Used as electrical insulation in wires and printed circuit boards.

Reason for choice: The chemical and physical properties of each mineral make it essential for a specific industry.

Application 6: Art, Jewelry, and Aesthetics (Symbolic and Decorative Use)

Scenario: A rare vein of granite containing garnet or amethyst crystals.

How it is used: After diamond cutting and polishing, this stone is used as a gemstone in rings, necklaces, or as a decorative object on a CEO's desk.

Reason for choice: Rarity, luster, and unique beauty that create high artistic and financial value.
