Is glass and feeder a thing? 10

First of all, 'feeder' and 'glass' are different things.

The feeder is located between the glass and the glass.

The difference between 'feeder' and 'glass' both contain lead oxide is that 'feeder' uses it as an auxiliary material, while 'glaze' uses lead oxide as the main material.

'Glass' also contains most of the components of glass, including (limestone, sodium carbonate, quartz sand, calcium, etc.), unlike glass, 'glass' is fired at a low temperature (about 800 degrees), while glass is fired at a high temperature of more than 1200 degrees.

The feeder is a traditional Chinese ancient glaze made by hand, which is the feeder. And glaze is a handicraft made with a mold with a modern formula. Before the Qing Dynasty, it was called Liuli, and the Qianlong Emperor felt that the word Liuli had the homonym of displacement, so he changed its name to Gong Material, and officially changed its name to Materializer after liberation.

The material of the feeder is more simple, and the craftsmanship of the production is emphasized. The glaze is modern and decorative.

Glass and feeder are different things.

The differences are as follows.

First, the main material. The main material of the glaze is lead oxide, and the main material of the feeder is glass with a low melting point.

Second, the process of formation is different.

Glass is a work in which raw materials are melted and poured into a special mold to form at one time.

The feeder is to melt raw materials such as silicates and other metal oxides at high temperature and pull them into rollers of various specifications.

Please, don't take the question for granted. Feeder and glass are a kind of glass products, and there are entries in the specific introduction. To put it simply, one is low temperature and the other is fired at high temperature.

I didn't come to get points, I happened to pass by, and I couldn't stand it anymore.

In the book "History of Chinese Arts and Crafts", glaze is also known as a material.

It's actually the same thing, there is a difference between having and not having a color.

Glass is an amorphous inorganic non-metallic material, which is generally made of inorganic minerals such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silica and other oxides.

The main component of ordinary glass is silicate double salt, which is an amorphous solid with an irregular structure. It is widely used in buildings to insulate wind and light, which is a mixture. In addition, there are colored glasses that are mixed with oxides or salts of certain metals to show color, and tempered glass that is prepared by physical or chemical methods.

Some transparent plastics are sometimes referred to as plexiglass.

Glass is artificial crystal in a variety of colors (color is produced from various metal elements).

Colored glass, also known as "ruli", is a rare ornament made of artificial crystal (containing 24% lead dioxide) of various colors (the color is produced by various metal elements) and fired at a high temperature of more than 1,000 degrees. Its color is colorful, and the quality is crystal clear and dazzling.

In ancient China, the original material for making glaze was obtained from the by-products produced during bronze casting, and then made into glaze after refining and processing, and the colors of glaze were varied, and the ancients also called it "five-color stone". In ancient times, because it was difficult for the people to obtain, people at that time regarded colored glass as even more precious than jade.

In June 2008, the glaze firing technology was selected into the second batch of national intangible cultural heritage list determined by the Ministry of Culture, and the glaze on the market is mainly dewaxed glaze represented by the south and handmade glaze represented by Boshan (Zibo). The more famous teams of domestic glaze production are glaze workshop, Renli glaze, Liuyuan, etc.

Precautions for the use of glass

Because the hardness of the glazed hand is relatively strong, equivalent to the strength of nephrite, but it is also relatively brittle and dusty, and cannot be slapped or collided hard, so after we have a glazed work, we should pay attention to its maintenance, and pay attention to it when maintaining, and do not collide or rub to move. to avoid scratches on the surface.

Glass maintenance should be maintained at room temperature, the real-time temperature difference should not be too large, especially not to heat or cool it by itself, the plane is smooth, should not be placed directly on the desktop, it is best to have a gasket; It is advisable to wipe with purified water, if tap water is used, it needs to stand for more than 12 hours to maintain the gloss and cleanliness of the surface of the glass, and must not be stained with oil stains and foreign objects; It is also necessary to avoid contact with sulfur gas, chlorine gas, etc.

Colored glass, also known as "glaze", is made of artificial crystal of various colors as raw materials, and is fired at a high temperature of more than 1,000 degrees. Its colors are cloudy and colorful; Its quality is crystal clear and dazzling.

The first material used to make glaze in ancient China was obtained from the by-products produced during the casting of bronzes, which were refined and processed to make glaze. There are many colors of glaze, and the ancients also called it "five-color stone". In ancient times, because it was difficult for the people to obtain, people at that time regarded the glass as more precious than jade.

In June 2008, the glaze firing technique was selected into the second batch of national intangible cultural heritage list approved by the Ministry of Culture.

At present, the reputation of the glaze on the market is mainly dewaxed glaze represented by the south and the hand represented by Boshan.

Summary. Liuli is an ancient Chinese material, it has a history of 2466 years, and has been used exclusively by the royal family since ancient times, and there are extremely strict grade requirements for users, so it is rare among the people.

Liuli is known as the first of China's five famous artifacts (gold and silver, jade, glass, ceramics, bronze), one of the seven treasures of Buddhism, and has been basically lost in the Ming Dynasty. However, even the very incomplete craftsmanship of the Ming Dynasty is still protected by the grade, and the glass at that time was already very impermeable, so it was called medicinal jade. "Ming System" contains:

The ornament given by the emperor to the champion is medicinal jade, which is only available above the fourth grade.

Classification of glass.

Class A ancient glaze, made of "glazed stone" and "glazed mother". Glazed stone.

Class B Taiwanese glaze, evolved from Western glass art. The origin is the ancient Egyptian "Fianse" craft. The analysis results of "Research on Ancient Chinese Colored Glass" show that:

The proportion of silica in "Fians" is 92%-99%, which is obviously different from the glass in the Zhou Dynasty in China. However, due to the similarity of the two shapes, some people call it Western glass.

Class C water glaze, today's common imitation glaze, made of unsaturated resin material, is characterized by light weight, knock on the sound of gold and stone without glaze, and easy to discolor, turbidity, no collection value, but ** very low.
