Posted by Satyendra on Jan 10, in Technical 0 comments Evolution of Blast Furnace Iron Making The origin of the first smelting of iron is concealed in the unrecorded history of human civilization. The first evidence of iron implements being used in ancient times actually comes from Egypt where an iron tool was found in a joint between two stones in a pyramid.

The origin of many prehistoric iron implements was probably meteoric iron. More than 4, years ago, people discovered meteoric iron. But it was another 2, years before the production of iron from mined iron ore began. When their empire collapsed around BCE, the various tribes took the knowledge of iron making with them, spreading it across Europe and Asia.

This layer retards the rate of further oxidation.

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.

Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others Whereas Lanphere and his colleagues referred to these two K-Ar ages of and million years, the ages are actually from another report and were obtained from samples collected at two localities in Canada, not Alaska.

There is nothing wrong with these ages; they are consistent with the known geologic relations and represent the crystallization ages of the Canadian samples. The Liberian example Table 2 is from a report by Dalrymple and others These authors studied dikes of basalt that intruded Precambrian crystalline basement rocks and Mesozoic sedimentary rocks in western Liberia.

The dikes cutting the Precambrian basement gave K-Ar ages ranging from to million years Woodmorappe erroneously lists this higher age as million years , whereas those cutting the Mesozoic sedimentary rocks gave K-Ar ages of from to million years. Woodmorappe does not mention that the experiments in this study were designed such that the anomalous results were evident, the cause of the anomalous results was discovered, and the crystallization ages of the Liberian dikes were unambiguously determined.

The Liberian study is, in fact, an excellent example of how geochronologists design experiments so that the results can be checked and verified. The final example listed in Table 2 is a supposed 34 billion-year Rb-Sr isochron age on diabase of the Pahrump Group from Panamint Valley, California, and is referenced to a book by Faure and Powell

It is fun to learn the history and origin of old cast iron cookware. It can also be a huge learning curve. Here are tips to help you with your research as you venture into the world of vintage cast iron skillet identification. This is an overview; there are many ins and outs and exceptions, of course.

The tuyere nozzle was connected to the bellows for the supply of air.

It would be extremely difficult for a person to consume more than 20mg of iron from their diet, Dr Shovlin said. Low dose supplements that can be bought over the counter at pharmacies and supermarkets typically contain around 14mg – the equivalent of a day’s intake. Women need more iron to remain healthy than men. The NHS recommends men need 8.

Most people should be able get all the iron they need from their daily diet. Women need more iron because of blood loss during menstruation. Pregnant women may also need iron supplements to ensure they get enough for their growing baby. Good sources of iron include dark leafy vegetables, brown rice, meat and fish, nuts and seeds eggs and dried fruit. Around six million British people take iron supplements — mostly to treat anaemia, a disease caused by iron deficiency, which causes feelings of exhaustion.

The NHS advises that taking 17mg or less a day of iron supplements is unlikely to cause any harm in healthy people. But for people low in iron, the standard dose in Britain is around mg a day. The study by Imperial College suggests that further research may be needed to see if this level is too high.

After that he dies. So a Brahma lives for 36, Kalpas, or 36, x 2, x 4,30, human years — i. After the death of each Brahma, there is a Mahapralaya or Cosmic deluge, when all the universe is destroyed. Then a new Brahma appears and creation starts all over again.

The continental nations of Europe are entitled to the credit of having fully developed the BF from the primitive method of producing iron blooms in a Catalan forge.

Axes and Swords for Beheading Beheading was a form of execution rather than a form of torture, but it could form part of a programme of torture. For example beheading was a part of the process of drawing, hanging, and quartering. Decapitation has been used as a form of capital punishment for millennia. The terms “capital offence”, “capital crime”, “capital punishment,” derive from the word caput, Latin for “head”, referring to the punishment for serious offences involving the forfeiture of the head.

Good sources of iron include dark leafy vegetables, brown rice, meat and fish, nuts and seeds eggs and dried fruit.

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic Stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria. While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae.

One genus of stromatolite very common in the geologic record is Collenia. The earliest stromatolite of confirmed microbial origin dates to 2. The most widely supported explanation is that stromatolite builders fell victims to grazing creatures the Cambrian substrate revolution , implying that sufficiently complex organisms were common over 1 billion years ago.

Factors such as the chemistry of the environment may have been responsible for changes. Cyanobacteria as well as extremophile Gammaproteobacteria are thought to be largely responsible for increasing the amount of oxygen in the primeval earth’s atmosphere through their continuing photosynthesis. Cyanobacteria use water , carbon dioxide and sunlight to create their food.

A layer of mucus often forms over mats of cyanobacterial cells. In modern microbial mats, debris from the surrounding habitat can become trapped within the mucus, which can be cemented by the calcium carbonate to grow thin laminations of limestone. These laminations can accrete over time, resulting in the banded pattern common to stromatolites. The domal morphology of biological stromatolites is the result of the vertical growth necessary for the continued infiltration of sunlight to the organisms for photosynthesis.

Layered spherical growth structures termed oncolites are similar to stromatolites and are also known from the fossil record.

Near Gettysburg, PA First an explanation on what is wrought iron Up until the mid s wrought iron was available. True wrought iron was produced by melting iron ore with silica in a furnace. Depending on the amount of refinement needed in the resulting wrought iron bar, determined the number of times the process of drawing out, cutting, and forge welding was performed.

A low quality wrought iron for nails and wagon wheels would be perhaps as little as 2 or 3 times through the wrought process. Higher quality wrought would go though the process more times for items of finer quality such as high end ironware for the kitchens of the wealthy. I tested a pair of old tongs once and found that one side of the tongs was low quality wrought while the other side of the tongs were much higher quality.

Through the opening between the tymp and dam, an operator ladled off the iron for mould casting and with an iron bar, called a ringer, pried away slag that stuck to the walls or accumulated around the tuyere nose.

The company used this early marking prior to , sometimes in combination with the Sidney name. This indicates that the piece is an authentic Wagner. Wagner made molded cast iron with a polished exterior and interior, and the best production was from to If the Wagner Ware logo is in the center of the bottom then it was made approximately If the is no heat ring and a stylized Wagner Ware logo then it was made between and He avoids Griswolds with the small logo and Wagner Wares that describe the pan by size — e.

If there is no heat ring on the bottom it was probably made between If there is a heat ring it could be another 10 years older. In another response he said: Matthew Griswold and John Selden produced hardware items. The company was renamed to Griswold Manufacturing Co. Notice the lack of a heat ring that was seen on the older pieces. These would either be in addition to or, in some cases, instead of the traditional size numbers. On some smaller pans, you may see a tiny numeral on the bottom of the handle.

Iron and Types of Iron

In addition to a “more sanitary condition,” iron bed frames offered consumers elegant, beautiful designs that many wooden beds couldn’t compete with. Because iron is a durable material that is less subject to breakage, many of these beds may be found in antique stores as well as city dumps today. If you have found a potential antique, you must study it closely to determine the date. The style of an iron bed can indicate its age.

It is clear that there is no increase in the values as a function of time.

Willamette Meteorite , the sixth largest in the world, is an iron-nickel meteorite. Iron meteorites consist overwhelmingly of nickel-iron alloys. The metal taken from these meteorites is known as meteoritic iron and was one of the earliest sources of usable iron available to humans. Those artifacts include, for example, a bead from the 5th millennium BC found in Iran [2] and spear tips and ornaments from Ancient Egypt and Sumer around BC. Meteoritic iron is very rare, and the metal was probably very expensive, perhaps more expensive than gold.

Some pseudofossils, such as dendrites , are formed by naturally occurring fissures in the rock that get filled up by percolating minerals.

Its most important property is that it is very soft. It is easy to work and shape and is just soft enough to cut through with quite a bit of difficulty using a knife. Pure iron can be hammered into sheets and drawn into wires. It conducts heat and electricity and is very easy to magnetize. Its other properties include easy corrosion in the presence of moist air and high temperatures.

Commercial pure iron has many different characteristics which include i improved resistance to corrosion and oxidation, ii excellent magnetic properties, iii high chemical and metallurgical purity, iv very good hot and cold forming capability, and v suitability for all types of welding. Pure Iron is largely used in the production of relatively small volumes of special alloy steels, in the aviation, automotive, construction, petrochemical industries, and in the manufacture of magnets, gaskets, fuse wire, welding rods, lighting conductors and MRI magnetic resonance imaging scanners.

However, it no longer qualifies since current standards for commercially pure iron require a carbon content of less than 0. Wrought iron is soft, ductile, magnetic, strong with high elasticity and tensile strength, malleable and hence it can be heated and reheated and worked into various shapes, becomes stronger the more it is worked, and suitable for members in tension or compression.
