What is ceramics?

In museums, of course, you have seen various vases, vessels, cups and dishes made by potters. Pottery items are made from special clay while it is soft and then fired in kilns to harden it. The art of making such things is called pottery. The word "ceramics" is sometimes used not only in relation to products made of clay alone, but also to products covered with enamels and glass. But in any case, for the manufacture of these products, firing methods and natural materials are used: clay, sand and crushed rocks.

Ceramics is one of the most ancient arts on earth, as clay is found almost everywhere. Sherds made in prehistoric times were found. A well-fired pottery is very durable. It may break, but it never rots or rusts.

The ancient Chinese were wonderful potters. They invented a process for producing a very strong, translucent ceramic known as porcelain. In the West, this material became known under the name "china", like the country itself, where it was first produced. There are six main types of clay used to make pottery.

The first is ordinary clay, which is not suitable for fine work. What is obtained from it is called earthenware or ceramic dishes.

The purest clay is kaolin, or Chinese clay. It is used to make Chinese porcelain. When fired, it acquires the purest white color. In ancient times, when there were no refrigerators, earthenware jugs were used to store cold water. The water in them remained cold because this type of ceramic is a rough material and allows liquid to seep into its fine pores. Leaking out, the liquid begins to evaporate, and this constant evaporation of moisture from the surface of the vessel helps the jar and its contents to remain cold.

In modern times, earthenware is coated with a special shiny compound to prevent this evaporation, and such dishes are usually called not earthenware, but ceramics.

How did the atheist's request to kill him with magic end?

On March 3, 2008, the atheist Sanal Edamaruku challenged a well-known Indian sorcerer on a popular Indian TV show, asking him to demonstrate his power on him - to kill with magic. For several hours the sorcerer unsuccessfully performed ritual actions, and, having not achieved success, he concluded that the atheist was "protected by a very strong deity."

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. ... >>

5W fast wireless charging IC from Toshiba 15.01.2014

Toshiba Electronics Europe (TEE) announced the release of an improved TB6865FG power transmitter and TC7763WBG receiver chipset.

The new set will allow faster wireless charging of mobile devices. The ICs support 5W of power transfer and allow simultaneous charging of two freely placed mobile devices. Features include a precise foreign object detection (FOD) function and an integrated digital logic controller that greatly simplifies the design.

The new chips are developed in response to the growing demand for efficient wireless charging of mobile devices. One emerging area of ​​application for wireless charging is waterproof mobile gadgets—devices completely encased in an airtight shell. The tightness of such devices is guaranteed due to the absence of any external connectors.
