- The Bessemer Process was a method of steel production invented by Henry Bessemer that involved forcing air through molten pig iron to remove impurities like carbon.
- The process took place in a large container called a Bessemer converter, where air was blown through molten pig iron, oxidizing it and reducing the carbon content to the desired level for steel.
- Before the Bessemer Process, steel was too expensive to produce in large quantities and was made through more costly methods, but the new process reduced the cost of steel production significantly.
Brass is a metallic alloy that is made of copper and zinc. The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
Iron: A strong, hard magnetic silvery-grey metal, the chemical element of atomic number 26, much used as a material for construction and manufacturing, especially in the form of steel.
Steel: A hard, strong grey or bluish-grey alloy of iron with carbon and usually other elements, used as a structural and fabricating material.

A Brief History of Steel & The Mysterious EutecticKen Newell
The second agricultural revolution coincided with the Industrial Revolution; it was a revolution that would move agriculture beyond subsistence to generate the kinds of surpluses needed to feed thousands of people working in factories instead of in agricultural fields. Bessemer’s invention of cheap steel was the cornerstone of both revolutions.
Revisiting the history of steel production process and its future direction (...POSCO Research Institute
[Asian Steel Watch] Vol.1(2016.1)
Steel is one of the most fundamental industrial materials that has sustained human civilization for millennia. Backed by rich steelmaking esources and reserves, the steel industry has continued to grow thanks to the superior characteristics of steel materials, economic and efficient mass production, and the evolution of steel technology. While adapting to the changing business environment, the steel industry will continue to develop in step with the progress of human civilization. This article examines the evolution of steel technology throughout history, and forecasts the future development of the steel production process.

1. How new modern materials prompted changes in architecture in the late nineteenth century in
reference to the construction of the Crystal Palace or Eiffel Tower.
After the Baroque faded slowly away, eighteenth-century architecture consisted primarily of
revivals of previous periods. This time was to be the calm before the storm, for the approaching
Industrial Revolution was to change everything about the world as it was then, including
architecture. Previously, building materials had been restricted to a few manmade materials
along with those available in nature: timber, stone, timber, lime mortar, and concrete. Metals
were not available in sufficient quantity or consistent quality to be used as anything more than
ornamentation. Structure was limited by the capabilities of natural materials. The Industrial
Revolution changed this situation dramatically.
In 1800, the worldwide tonnage of iron produced was 825,000 tons. By 1900, with the Industrial
Revolution in full swing, worldwide production stood at 40 million tons, almost 50 times as
much. Iron was available in three forms. The least processed form, cast iron, was brittle due to a
high percentage of impurities. It still displayed impressive compressive strength, however.
Wrought iron was a more refined form of iron, malleable, though with low tensile strength. Steel
was the strongest, most versatile form of iron. Through a conversion process, all of the impurities
were burned out of the iron ore, then precise amounts of carbon were added for hardness. Steel
had tensile and compressive strength greater than any material previously available, and its
capabilities would revolutionize architecture.
This change did not happen over night. Prior to the introduction of bulk iron, architecture relied
on compressive strength to hold buildings up. Even great structures like the Chartres Cathedral
or the Parthenon were essentially orderly piles of stone. Architects were accustomed to thinking
of certain ways of creating structure, and though they glimpsed some of the possibilities of the
new materials, the first applications were made using the old ideas.
The explosion in the development of iron and steel structures was driven initially by the advance
of the railroads. Bridges were required to span gorges and rivers. In 1779, the first iron bridge
was built across the Severn River in Coalescence, England. It was not an iron bridge as we might
conceive of it today, but rather a traditional arch made of iron instead of stone. The compressive
strength of limestone is 20 tons per square foot. The compressive strength of cast iron is 10 tons
per square inch, 72 times as high, permitting significantly larger spans. Later, the truss, long used
in timber roofs, became the primary element of bridge building. A triangle is the strongest
structural element known, and applied force only makes it more stable. When a diagonal is added
to a square, the form can be viewed as two triangles sharing a side, the fundam.
Portable X-ray Fluorescence (PXRF) for Compositional Analysis of Early Americ...Olympus IMS
Handheld XRF analyzers are used worldwide to provide highly specific material chemistry for rapid and accurate identification of alloys and metals. Industrial requirements for quality control, plant maintenance, and profit/loss have prompted portable XRF manufacturers to minimize measurement times, ruggedize analyzer housings, simplify operation, extend the elemental range and detection limits, and improve the accuracy (correctness) and precision (reproducibility) of the results.
The nuances of archaeological, conservational, and collectible metalware analyses are similar to those for industry. The objectives of the analysis, the representativeness of the sample measurements, and the condition of the sample are all important considerations. Part of a private early American metalware collection in Salem, Massachusetts, was made available to illustrate the versatility of portable, handheld XRF measurements.

7. Bessemer's process made steel comparably priced to wrought iron. Steel allowed great strides in transportation, shipping, building and weaponry. Higher strength steel components produced more powerful engines, guns, tanks, and naval ships. The mass production of steel led to turbines and generators that made harnessing water and steam power plausible. The effects of Bessemer's process extended across the world and have changed the way we live today. Henry Bessemer Andrew Carnegie
