Great discoveries hidden from the world

Great discoveries hidden from the world
.....😇😇😇❤️❤️❤️.....
Even today, scientists are working day and night to make new discoveries. When an important discovery is made, all records of how it was made are usually kept. It is to produce the same product again and again without difficulty.
Thousands of years ago, people made important discoveries. However, due to various reasons, the production process or the raw materials used in some of them have been completely lost to the world today. No one has been able to reproduce them no matter how hard they try. These are some of the great and important designs.
1.Damascus steel

'Damascus steel', which was made in Syria as the center, was used to make military tools like swords. These are very strong and sharp, and this is due to the fact that this type of steel contains finely processed strong carbon fibers.
Made from the 3rd century to the 17th century AD, specially shaped iron was imported from India and Sri Lanka as raw material for this type of metal. The composition of these special irons is still a secret, and here the structure has been obtained by mixing things like wood and leaf pieces with ordinary iron.
By the end of the 17th century, production of these had stalled and was completely discontinued. The reason for this is the shortage of raw materials caused by the blocking of trade routes. Although many attempts have been made to reproduce these with the help of modern technology, they have not been successful so far.

1. Starlight
   Between the 1970s and 80s, a young chemist, Mr. Maurice Ward, made a wonderful discovery. This material, named Starlight, could withstand temperatures of up to 10,000 degrees Celsius.
   Many organizations, including NASA, quickly realized the importance of his discovery and offered to contribute to their production and further research. However, Ward A, who was afraid of losing the right to this kind of discovery, did not allow anyone to have samples of his discovery and refused to give its chemical composition to anyone. He stated that in order to give it, he should get 51% of the rights of all the products made using it.
   Ward died in 2011. Even then, he had not told anyone about the production of Starlight and had left no notes or samples about it. After that, many people tried to reproduce it, but none of them succeeded.
2. Roman plaster
   The Roman mortar used for the construction of buildings in ancient Rome is very high in terms of strength and durability. Between 300 BC and 476 AD, these have been widely excavated and parts of some of the constructions made from these are still in good condition today.
   Limestone, stone chips and porcelain ash have also been used to make this mortar. Pozzolana is a type of ash that is deposited around the volcano after the eruption.
   The use of Roman plaster gradually declined after 500 AD and died out after the fall of the Roman Empire in the 14th century. They briefly came to the fore in the 18th century, but soon fell out of use. At the present time, the use of ash for construction work is being re-discussed after conducting a number of researches on the strength of ancient Roman mortars. The use of these is also more environmentally friendly, and further studies are being conducted on the composition of the Romans.
3. Flexible glass
   A composer who lived there during the Roman Empire made a wonderful discovery. It is the production of an unbreakable, flexible type of glass. He used his invention to make a glass vase and presented it to Tiberius Caesar, the emperor at the time.
   Tiberius tried to break it, but he could only bend it. The creator easily restored it to its original shape with the help of a hammer. He expected to receive praise and gifts from Tiberius, but something else happened. Tiberius, who speculated that even the price of gold may drop in the near future due to this design, ordered to capture its designer and behead him.
   With the beheading of the creator, all the secrets of this new discovery were also buried. The reason is that he has not recorded anything about it. After that, many people tried to produce something like this, but no one succeeded.
4. Crystallization and preservation of dead bodies
   In 1792, Girolamo Segato, born in Italy, invented a wonderful method of preserving corpses in a living form. Having studied Egyptian mummification at a young age, he was able to successfully experiment with a special method of crystallizing a corpse instead of removing water and preserving it in a living form without spoiling.
   Many who witnessed Segato's adventure said that he had become accustomed to Egyptian magic, and therefore its curse would be upon him. Afraid of this, he destroyed all the research notes he had written on it.
   By 1836, he was very afraid of losing his life, and he urged his friend Pelligrini to inform him about his 'secret method'. However, he died before that. Along with this, his secret also disappeared and many people including Pelligreni tried that method using the facts they knew, but it all went in vain. The body parts still preserved by Segato in Florence, Italy
