During the Medieval period through the 5th and 15th centuries in Europe, technology advancement in metal forming and extraction was becoming popular. The reason for this is because of the battles and empires in the time periods having the desires to expand and build up their military. To complete this task, an edge in iron working and metal forming had to be solidified as a strength for those wanting to further expand their countries boundaries. An example of this would be the Roman Empire. (Source) This research paper is going to talk about how people in the medieval time periods extracted iron ore, what technology was utilized to make armor, and what armor was produced and how it was made in the middle age era.

“Bloomery” referred to the process at which the iron was made. (who used the bloomery). Iron ore would be smelted with hot charcoal.(Find temperature of a bloom versus blast furnace) A blacksmith would use a hammer and anvil to remove slag and form the iron ore into wrought iron containing 0.02% to 0.08% carbon which was absorbed from the charcoal. ( http://www.anselm.edu/homepage/dbanach/h-carnegie-steel.htm) The downside to this process is that iron would be full of slag due to the restrictions in size of the bloom furnace which ranged from 1m to 2m high (pg877 history of warfare). A bloom was portable and could be made virtually anywhere. A bloomery was made with stone, clay and other hard earth materials to support the high temperatures to smelt the iron ore ingots. For heating the bloom charcoal was used. Bellows were used to blow air into the furnace to increase the heating of the iron ore. The bellows can blow air into the fire either by hand or by a water wheel. (http://www.anselm.edu/homepage/dbanach/h-carnegie-steel.htm) The size of the furnace would restrict the size of the armor and the slag would interfere the strength of the armor. This limitation was noticed and an attempt to make the bloomery hearth larger would be made. When the bloomery was made larger this made the temperatures higher …show more content…
Wootz consists of high carbon (nearly 1.2%C to 1.6%C) crucible steel. This is first created by small pieces of iron in sealed crucibles and charcoal being heated into a cake. Then the mixture is left to cool slowly, and exported to manufacturers. The cakes would be manipulated by forging it into blades. Through this process, the cementite was broken up, decreasing the brittleness and created a watered silk texture to the blades surface. (The night an blast furnace pg 11, 12, 14) Wootz steel would be imported by Europe and also called Damascus steel.(History of Metallurgy pg
In the Medieval Times , life as an Armorer was difficult and hard working. As an Armorer in his daily life it was hard as a peasant. They would eat a very little and wear a very little. Also armorers wore blouses of clothes and skin fastened leather belt is round the waist and armorers went barefooted also in the winter. Since armorers were peasants they were poor so they had a limit on food. They usually would drink ale that was a type of beer because it was really popular for the lower class. As an educated peasant armorers were educated before the age 14. Another difficult task in the Medieval times was that armorers has land but it was mostly owned by Kings and Queens. Actually some armorers lived on their own small plot of land and
The iron industry was and still is now a very important and dangerous industry. It involved very dangerous tasks including mining in enclosed caves. Henry Oliver played a very important role in the iron and mining industry. Hope you enjoy!
The same year, parliament prohibited the building of any new mill in the colonies for the rolling or plating of iron ore and the steel could be created. Pig iron could only be exported to England.} (page 54)
The sequence of steps to successfully obtain steel became known as the Bessemer process, and this would be responsible for the extremely fast innovation within society. This is very evident, as not only did steel acquire several different uses within society, but the effects had greater, beneficial impacts than anyone could imagine. The biggest use that steel was required for, was the building of railroad tracks. Thanks to this invention, the concept of transportation was redefined for people. Instead of wagons and walking, someone had the ability to now board a train, and reach their destination much faster than before. Along with the creation of the railroad system, the usage of steel also allowed society itself to become more advanced, as cities could grow bigger and more complex. Back when iron was used, the height of the building was extremely limited due to its fragility. However, now with the product of steel, architects were allowed to make buildings as high as they wanted, which led to the creation of the world’s first sky scraper in
Andrew Carnegie was an Industrialist, he made steel out of iron. Now that the Bessemer Process was invented, it sped up the process of purifying iron by 96 times. What used to take us 24 hour now takes us 15 minutes, what that does is is purify the iron , and with iron being purifies at a faster rate, steel could be made at a faster rate.
The Medieval Machine by Jean Gimpel, shows information about the technological accomplishments of the middle Ages. The basic idea is that during the two centuries from around 1050 Western Europe went through a kind of industrial revolution that was just as important as of the nineteenth century’s.
One of technology advances that made it possible to produce more steel was Bessemer converter which
In the 19th century, we were already big with steel. But, here came Henry Bessemer and changed the whole concept of it so we can put that steel to use. He created the Bessemer converter, which converts iron into steel. With this converter, we started to get massive bridges, railroads, the first skyscrapers. The Washington Monument was made with this steel. America started to expand and got bigger and better because of this invention. “As a home industry, iron and steel making ranks fifth in the Unites States being exceeded in order, by agriculture, slaughtering and packing foundry and machine shop products and lumber and timber products. It furnishes work over a quarter of a million employee supports directly 1,000,000 people, and indirectly many other in tributary operations with their
Industrialisation and urbanisation developed during the late 1700’s. This was the process of companies removing physical labour and replacing this with machinery. The iron and the textile industries we’re two fields of work which played a big impact on the industrial revolution and the people who mainly benefited from these occupations were the very poor and working class.
New technologies were used such as alloying and casting metals for tools, weapons, and luxury goods.
During the 16th century England and much of Europe found itself in turmoil and in a constant state of war. The outbreak of fighting led to the invention and development of new weapons and the growth and change of weapons of old. The development of weapons was a trademark of the time, with a sort of renaissance, or re-birth in the field of weaponry (Miller). The technology was highlighted by the invention of gunpowder by the Chinese which eventually found its way to England (Grolier). However, the use of gunpowder was minimal, because the use of had yet to be perfected. The technological advancement most useful during the period was progression of the metals used in weaponry. The new forms could
In many states across the United States, laws have been passed regarding carrying guns on campus. In states where they do allow students to conceal a firearm they must meet certain criteria. For example only students over the age of 21 are able to legally carry a firearm on campus with a handgun license. As mentioned in the beginning many any states have passed this law, but across the United States there are still a lot of states who debate on whether they should allow their own students to conceal a firearm on campus. Back in the 1900’s many students had access to rifles because it was part of a sport. Across the United States hunting was a hobby for many college students. The idea of student’s being allowed to carry firearms on campus often carries different emotions for people across the United States but it’s important to understand the different arguments related to the topic because we are part of the problem. Citizens take the time to preach what is wrong with this country but in reality what are you really doing in regards to keeping our citizens safe, is anyone safe in this country, are our own college students safe when stepping foot on campus?
Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.
With the technology advancing, the production of material moved from small shops and homes into large factories for mass-production. This included steel industries that allowed the transfer of “…manufacturing plants away from naturally flowing waters (outside the city) to areas inside and around the cities where more abundant labor was available”.
Recently the firms were supposed to change their marketing strategies from product-oriented to customer-oriented. In this context, the firms need to provide “what they have to provide into the market” rather than “what they want to provide into the market”. In addition, the firms should allocate their resource into the appropriate domain for which the customer really wants. For the purpose, the firms need to analyze the external environments.
