Who Invented Silk?

The Silkworm Legend Silk has its origins in China. According to them, the first person to discover it was the Yellow Emperor’s consort, Hsi Leng Shih in 3,000 BC. One day she sat under a mulberry tree in the royal garden to enjoy her tea. A cocoon fell from above into the hot liquid. When it did the strong silk thread unwound itself. The empress began raising silkworm and also invented the loom. In honor of her discovery, they gave her the title “Silk Goddess.” Archeological Evidence of Silk A recent archeological discovery appears to contradict this legend. It is a cup made from ivory and inscribed with silkworm designs. Along with the cup, they also found silk-making equipment. The items are believed to be about 6,000 to 7,000 years old. This has led experts to believe that silk must have been invented some 10,000 years ago! Excavations in China reveal further evidence of silkworm farming. In 1927 they found part of a cocoon along the Yellow River. It was estimated to be from between 2,500 to 2,300 years BC. Another find was a group of threads, ribbons and other pieces of silk dating as far as back 3,000 BC. These were unearthed in Zhejiang province. Use of Silk Silk was highly prized by the Chinese. At first, only royalty could wear it, notably the Emperor, his chief consort and his heir. Favored colors were white and yellow. Commoners were banned from using it. However people used silk in other ways. They would use it as parts for bow strings, musical instruments and fishing equipment. Silk was even used as currency. Eventually the old laws went lax and everyone could wear silk just like their king. Silk was quite...
Who Invented the Ironing Board?

Who Invented the Ironing Board?...

After the emergence of the iron, many had lesser predicaments regarding the look and feel of their clothes that they wear. But using the early models of the iron still posed a new problem: Where to iron the clothes? That question seemed to be voiced by a lot of people before a black woman, who invented the ironing board, came to help the people have an easier time to iron clothes. Who is this woman who invented the ironing board? The Known Creator of the Ironing Board During the 19th century, a former slave named Sarah Boone gained a worthy achievement that brought this inventor not only glorious fame and success, but also hostile detractors who didn’t believe in Boone’s invention that much. Nevertheless, this invention of the ironing board was patented, and Boone was said to be among the first African Americans who garnered a patent for a particular useful invention. Its patent (U.S. Patent #473,653) was done in the 26th of April in 1892. Doubts about Boone’s Invention As aforementioned, not everyone actually really accepted Boone’s invention of the ironing board. Some argue that this model was merely an improvement of earlier and existing versions made by others. According to these people, Boone wasn’t the first who invented the board for pressing clothes. However, most people say that these claims may seem to be inaccurate even if there are actual records of a number of early inventions of this product. The Features of the Ironing Board Invented The ironing board that Boone designed and invented had a number of useful features: Those who had seen the patent can see that the design had a curved and narrow design. It was also reversible. And that made it simpler...
Who Invented Plastic Wrap?

Who Invented Plastic Wrap?...

Plastic wrap is such a common and ordinary thing you can find in every house every day. If you have food left over after a meal it is sometimes quite common to put them in a plate and cover them with this film. The idea is to cover and seal off any food you want to put inside containers in order to keep them fresh. Its invention is credited to Ralph Wiley from Dow Chemical. You will usually get plastic wrap in rolls contained in boxes. Each box usually comes with a cutting edge to make cutting the plastic film a lot easier. Every plastic film sticks to containers like an adhesive sealing food tight. It takes on different names depending on the location. In the United Kingdom, it’s called a cling-film. Some people in the United States call it cling wrap while it is called glad wrap. Invention of the Plastic Wrap The very first sheet of plastic ever used for wrapping anything was called cellophane. It was invented by Jacques Brandenberger, a Swiss chemist, in 1911. It was used as packaging and was quite favored due to the fact that it was transparent. However, it was never used to wrap or seal food. Needless to say, that isn’t the same as the plastic wrap that we use nowadays. The plastic wrap that we are familiar with is used primarily to wrap or cover food. Saran is the very first sheet of plastic to be used to wrap food. Saran or Saran Wrap is a trade name of Dow Chemical. This actually refers to various polymers and monomers that has properties that act like a barrier. Compared to other plastics, this plastic wrap is able to contain aroma...
Who Invented the Skyscraper?

Who Invented the Skyscraper?...

Defined as a super tall building that is continuously habitable, a skyscraper is a fascinating invention. The Empire State Building in New York City, the Willis Tower in Chicago and the Taipei 101 in Taiwan are just some of the most impressive skyscrapers ever created. Today, these buildings serve as practical solutions to the increasing scarcity of land worldwide. Aside from these things, it is also good to know the history of these tall buildings including who invented the skyscraper. The Invention of the Skyscraper Who invented the skyscraper? After he created the first ever load-bearing structural frame for the Home Insurance Building within the City of Chicago in Illinois in 1885, it is but right to credit architect William Le Baron Jenney as the Father of American skyscrapers. The ten-storey building was the very first skyscraper in the world. In 1891, American architects Louis Sullivan and Dankmar Adler designed the Wainwright Building in Saint Louis, Missouri. It was also a ten-storey building. However, many people considered it the first true skyscraper rather than the Home Insurance Building because it was constructed with steel frames. Furthermore, it featured vertical bands, which helped emphasized the building’s height even more. Additional Facts and Other Interesting Information After the early skyscrapers were created, fire restrictions and height limits were introduced. In 1895, the American Surety Building was completed in New York. It was the tallest building during that time. In 1930, the Chrysler Building was completed in New York City. In 1931, the Empire State Building, which was comprised of 102 floors, was completed. In 1932, the Boerentoren was constructed in Antwerp, Belgium. It was made up of 26 floors. In 1940, the Torre Piacentini was completed with 31 floors within the...
Who Invented Chalk?

Who Invented Chalk?

Your first encounter with chalk might have been in the classroom where you often see your teachers use them to write on a chalkboard. The most familiar form of chalk a lot of people have come familiar with is made of slender sticks around a quarter of an inch thick and about three inches long. You might even have come to wonder who invented chalk. Who Invented Chalk It might come as a disappointment to find out that no one can tell who invented chalk. Chalk is readily found in nature and has been used as a tool for drawing and writing for quite a long time. Drawings that date even to the prehistoric times have been discovered by archaeologists. The earliest chalk writings/drawings have been found in caves. As time went by artists from various countries used chalk to make drawings and sketches. Their work was protected using shellac or any comparable substance. For the convenience of these artists, a major innovation was introduced – chalks shaped into sticks. Even though chalk artists can’t be credited as the ones who invented chalk, their need introduced an innovation that would last for centuries. Making Chalk In the same way we don’t know who invented chalk, we also don’t know who invented the method to make chalk into sticks. What we know is that the method starts by grinding natural chalk into a very fine powdery form. Water is then added along with clay and various color pigments depending on what color of chalk you want to make. The clay actually acts as a binder of some sort. The mixture will initially look something like putty that would be rolled and shaped into cylinders and then would be left to...
Who Invented the Outhouse?

Who Invented the Outhouse?...

Bowel movement being a basic universal need, it’s easy to imagine how the man who invented the outhouse came up with the idea. But who was the first latrine maker? Prehistoric Times Defecation in ancient times is thought to have been done indiscriminately. Prehistoric men released human waste anywhere in the forest. But soon, as the idea of privacy was beginning to take shape in their minds, they began to do it in isolation in caves. This was the crudest form of an outhouse by the first latrine maker or makers. Some studies estimate this to have happened about the same time when man learned to dress up. But the problem of available space in the latrine caves soon started troubling them. Thus, probably for convenience sake, they started digging holes for the purpose and partly refilling it with earth to make it reusable by others. Then, as refilling reached the level of the ground, they dug another site. As they advanced in living standards, people started living in constructed shelters of wood and thick canvas, and much later, wood and stone. The idea of communities also began to propagate. About that time, caves were too isolated and dangerous to continue serving the defecation needs of the people. The person or persons who invented the outhouse came up with the idea at this time. It Really Started in China The earliest record of a water closet system was in China. A stone toilet bowl with a water system was found to have been used in 206 B.C. Thus, the first latrine maker and the person who invented the outhouse could well have been a Chinese who lived around this time. Outhouses in Europe Some experts estimate that the first...
