The History of Ancients Faith  

---

The trust of the ancients Stone is able to provide the power of the resulting natural energy and can give aura, both positive aura physically and psychologically and will give more value of its magical energy and contain energy that influences the wearer. The energy of this stone that can be felt derived from the aura of energy power from the strength of the stone, so its energy is not from the magical creatures inside but from each agate will have its own energy that can also affect, depending on the user's intention as a positive or negative force.

Metal Alloy

---

Metal is a chemical element that has strong properties, clay, hard, electric and heat conductor, and has a high melting point. Metallic ores are found by means of mining in pure state or mixed with elements such as carbon, sulfur, phosphorus, silicon, and impurities such as clay, sand and soil.

Metals can be divided into several classes, namely:
1. Heavy metals: iron, nickel, chrome, copper, lead, and lead
  zinc.
2. Light metals: aluminum, magnesium, titanium, calcium, potassium, sodium,
  And barium.
3. Precious metals: gold, silver, and platinum.
4. Fireproof metal: tungsten, molybdenum, titanium, and zirconium.

In use and usage, the metal is generally not a metal compound, but is an alloy. Metals and alloys are important engineering materials, used for the construction of machinery, vehicles, bridges, buildings, and aircraft.
Due to its usage of mechanical engineering, the important metal properties are mechanical, physical, and chemical which determine the quality.

Iron ore is a raw material for making iron which can be a compound of oxide, carbonate, and sulphide and mixed with other elements such as silicon. Iron ore is processed in a furnace or kitchen high to produce coarse iron. Rough iron is a raw material for cast iron, wrought iron, and (steel) .The three kinds of materials are widely used in engineering.
Steel is a metal alloy between iron and carbon with a maximum theoretical carbon content of 1.7%. Cast iron is a metal alloy between iron and carbon, which measures from 1.7% to 3.5%. Wrought iron is a steel that has a low carbon content.
Judging from its usefulness, iron and steel blends are the backbone of modern civilization today for transportation, building, agricultural and machine tools.

Material of Iron Origin

---

The iron raw material is iron ore whose iron percentage should be as big as possible. Iron is an ferro oxide (Fe2O4 and Fe2O3) or iron carbonate (FeCO2) called spatial iron stone. Raw iron processing in high kitchens is done by reducing iron ore using coke, auxiliary materials, and hot air.
Iron ore imported from mines in various grades and chunks that are not as large, and mixed with rock and clay.  

Minerals are a substance that is abundant in the earth, which has special features and features and has a constant chemical composition. While rocks are a combination of two or more minerals and have no fixed chemical arrangement. Ore is a mineral or rock that contains one or several kinds of metals in a considerable percentage to be used as a mine. The amount of metal contained in the ore varies. Metals in pure state are rarely found in the earth, most of which are oxide, sulfide, carbonate, and sulfate compounds that are metal ores that need to be processed into useful metals for humans.

The main ingredient for making crude iron is iron ore. Various kinds of iron ore contained in the skin of the earth in the form of iron oxide and iron carbonate, among which the most important is as follows.
1. Brown iron stone {2Fe2O3 + 3H2O} with iron content ranges from 40%.
2. Red iron stone also called hematite {Fe2O3} with iron content ranges from 50%.
3. The magnet iron {Fe2O4} stone is dark greenish black, magnetic with iron content of 60%.
4. Calcite or spat calcite stone {FeCO3} which is also called spherosiderite with iron containing about 40%.
The iron ore from the mine is usually still mixed with sand, clay, and rocks in uneven boulders.

Temperature and Chemical Reaction

---

The principle of high temperature process is the principle of reduction. In this process carbon monoxide substances can absorb the acid from the iron bonds of acidic substances at high temperatures. At high temperature combustion + 1800oC with hot air, then the temperature is generated that can carry out the reduction. In order to avoid a deadlock because the process takes place then given limestone as an additional material. The additives are acidic when the iron ore has an alkaline character and otherwise the auxiliary additives are provided which is alkaline when the iron ore is acidic.
The gas formed in the high kitchen is then streamed out through the top and into the air heater. The dripping slag protects the rough iron from the oxide by hot air being inserted, the slag is then separated. The process of reduction in the temperature high goes on as follows:
Charcoal from coke burns according to the reaction: 

C + O2 => CO2

part of CO2 together with charcoal to form a substance that is located on the top of the gas 

CO2 + C => 2CO 

At the top of the kitchen high at temperatures from 3000 to 8000 C higher iron oxides are converted to lower oxides by indirect reduction with CO according to the principle:

 Fe2O3 + CO => 2FeO + CO2

At the time of the process the charge goes down and there is an indirect reduction according to the principle: 

FeO + CO => FeO + CO2

This reduction is called indirectly because it is not a pure charcoal that reduces but compounds the carbonaceous substances with oxygen. While direct reduction occurs in the hottest part of the kitchen, which is directly above the penetrating pipe. This reduction takes place as follows.

 FeO + C => Fe + CO

It is the CO that rises upward to make the indirect reduction. Every 4 to 6 hours of high temperature.

Conclusion

---

Iron Stone has high moisture content and contains many elements of ferrous metal so it can be attached to magnet iron. In addition, this stone can also absorb the energy of heat so slightly reflect light.
