When was the first pottery made?

Wet clay can be molded into any shape. After a few days, the clay will dry out and become hard. If the clay is dried or fired, its structure changes. Products made from fired clay are called ceramics. Ceramic vessels are called pottery. The first pottery was made about 10 thousand years ago. To prevent the stored grain from spilling through the holes in the baskets, these baskets were coated with wet clay from the inside. Perhaps one day one such basket fell into the fire. The reed burned down, and the first pottery was made.

There are three types of pottery - pottery, pottery and porcelain. The simplest type of pottery - earthenware - is made from clay and fired. It is porous and slowly passes water. As time went on, people learned that some stones can be melted into a kind of glass. Stones were crushed and mixed with clay. Pottery made from such clay is called pottery. Ceramic products do not pass water and can be used for cooking on fire.

During the Tang Dynasty (618-906), the Chinese began to make a different kind of pottery. They were made from special white clay mixed with crushed stones. Such pottery, called porcelain, was fired in kilns at a temperature sufficient to melt iron. Porcelain products were translucent (light could be seen through them) and durable. Around 3300 BC, the potter's wheel began to be used. The potter placed a piece of clay on a circle in the center. During the rotation of the circle, he gave the clay the necessary shape, pressing on it with his fingers. Pots made on a circle are always round.

People of all ancient civilizations - Egyptian, Persian, Mesopotamian - made beautiful pottery. The Egyptians used icing in many colors. The Persians were painting their pottery as early as 4000 BC. The ancient Greeks and Romans also made large earthenware vases. But the most beautiful pottery in ancient times was made by the Chinese.

In what ridiculous way did American lawyer Clement Vallandigham die?

In 1871, Clement Vallandigham, an American lawyer, handled a case defending a man accused of murder over a bar quarrel. He built the proof of innocence on the fact that the victim himself accidentally shot himself, taking a gun from his pocket in an uncomfortable position. Vallandigham wanted to visually demonstrate this development by putting another pistol in his pocket (as he thought, unloaded). As a result, the lawyer, taking it out, shot himself. He died from his wound, and his client was acquitted.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

New membrane will reduce the cost of water filtration 05.01.2021

Researchers from the University of Texas at Austin and Pennsylvania (USA) have created a new membrane for water purification with a uniform density at the nanoscale. This structure of the membrane allows you to get more clean water and make the filtration process cheaper.

Desalination membranes remove salt and other chemicals from water. The way the purification takes place is a seemingly very simple process: salt water is passed through a filter - pure water flows out from the other side. But there are many subtleties and complexities within the process.

The research team determined that the desalination membranes are incompatible in terms of density and mass distribution, which can hinder their performance. Uniform density at the nanoscale is the key to increasing the amount of pure water that these membranes can produce. The uniform density made the new membrane significantly thicker than current counterparts. However, as previous studies have shown, thick membranes are actually more permeable. This came as a surprise because the thickness was thought to reduce the amount of water that could pass through the membranes.

Scientists have developed three-dimensional reconstructions of the nanoscale structure of the membrane using modern electron microscopes. They modeled the path that water takes through these membranes to predict how efficiently the water could be purified based on the new structure. In the article, the authors report that the efficiency of the membranes has become 30-40% higher. This means that they can purify more water with significantly less energy consumption. The opening could expand access to clean water and lower water bills for both individual homes and large farms.
