This six-color glazed snuff bottle with floral yellow cover is 6.2 cm high and 5 cm wide.
The yellow colored glaze is the body, which is covered with six colored colored glazes: red, yellow, green, blue, purple and black.
Carved with lotus flowers, branches and leaves, frogs and other figures.
This one must be a rare and exquisite workmanship.
There is still the last bit of red material left, but this time Chen Wenzhe mixed it with ruby red material.
Since there aren't many, I can only make a simple vessel.
After thinking about it, Chen Wenzhe chose ruby red cloud bat pattern wash.
This kind of utensil is oblate in shape, white stone red in color, and has a deep and gorgeous color.
The whole body of the vessel is engraved with patterns of clouds and bats, which are simple and solemn, thick and full of atmosphere.
This is the last glass product, and Chen Wenzhe will call it a day after finishing it.
It was at this time that Cao Qingchun came over. He was very interested in seeing Chen Wenzhe's movements.
Chen Wenzhe also didn't expect that he didn't even know how Liuli was made.
To put it simply, to make colored glaze, you first mix various pigments, melt them in a high-temperature furnace, and then wrap the molten glass with an iron rod and keep rotating it.
Then use a blow tube to take out the glass body. After taking it out, you can shape the glass and blow it with a blow tube.
After the colored glaze is formed, it is stored in a heat preservation kiln for four days. If it does not burst, the colored glaze is ready.
To put it more carefully, you need to first select the various colors of paint you need and wash these paints carefully.
After mixing it in proportion, it is melted in a 1400 furnace and refined into crystal glass.
The molten glass is wrapped around an iron rod and kept rotating in the furnace.
Then take out the glazed body from the high-temperature stove with a 1.5-meter-long blow tube.
After taking it out, keep rotating the glass to give it shape.
The temperature of the stove is very high, and the newly taken out glass is softened to a good degree, making it easy to shape the glass.
However, the modeling technique must be fast, because the colored glaze will gradually cool down.
When shaping the shape of the glass, you should use a blow tube to make the shape of the glass better.
However, the blowing scale needs to be carefully controlled, otherwise the glass production will fail.
After the glass is finalized, it can be placed in a 500-meter heat preservation kiln for four days.
If the glass does not explode, it means the glass is finished.
Therefore, the entire process of making colored glaze works is not difficult.
Of course, rotating glass, shaping and blowing still require experience.
But compared to the process of making porcelain, the process of blowing glass products is much simpler.
It can also be seen from here that the most important thing is to mix various pigments.
Because whatever color you mix, you will eventually get what color colored glaze you get.
To put it simply, colored glaze refers to glass works made of artificial crystals of various colors as raw materials and dewaxed at high temperatures using the ancient bronze lost-wax casting method.
Its colors are flowing and beautiful, its quality is crystal clear and dazzling.
But among the many colors of colored glaze, which color is the most rare to find? How are the colors of these colored glazes formed?
Very few people know this. Let’s talk about red first, because red is the most difficult color to come out.
In the past, red was rarely used in the production process of colored glaze.
Cost is one aspect, but more importantly, no one in the industry has mastered this technology.
Starting in 2007, when everyone was preparing gifts for the Olympics, they started researching.
Because the relevant organizers proposed that the Olympic Games will be held in our country, and red will definitely be the main color.
In this way, can the colored glaze be made red?
This promoted the progress of the research and development of red colored glaze, and finally produced a batch of red colored glaze.
Because the technology was not very mature at that time, many reds were burnt to look like iron embroidery.
After the Olympic Games, many companies in the industry are also stepping up the development of red.
Then came the 2010 World Expo held in Dahai City, and another batch of red colored glazes emerged.
At this time, the red colored glaze is relatively mature and the color is more pure.
The development of red is now better than before, a lot, but it is not perfect. So far, red is still leaning towards purple.
So what raw materials are used to make red? In fact, there are two kinds of materials to make red.
The first is cuprous oxide, which is a monovalent copper oxide.
The second type is colloidal Au, also known as colloidal dispersion, which is a homogeneous mixture.
Colloids contain substances in two different states, one dispersed and the other continuous.
The dispersed part is composed of tiny particles or droplets, and the dispersion particle diameter is between 1nm and 100nm;
Colloid is a type of dispersion particle with a diameter between that of a coarsely dispersed system and a solution. It is a highly dispersed multi-phase heterogeneous system.
Therefore, red colored glaze is still very precious, even in modern times.
Then there is blue-green colored glaze. The blue-green color in colored glaze is the most commonly used color.
After the colored glaze is introduced from Wanwan, this is the basic color.
It is also the most widely used color, and its main component is copper oxide.
Light yellow is called gold in the industry. This color caters to the hobbies of some rich people and is generally used for seals and Buddha statues.
Used on Buddha statues, it is mainly used to show the majesty of the Buddha statue.
The main component of light yellow is cadmium oxide. Cadmium is a highly toxic substance, but it is relatively stable after being oxidized and can produce wonderful colors.
Therefore, it has been widely used in recent years. It is also one of the less stable colors. The color of each batch of goods may be different.
In this way, you can see which colors of colored glaze are rare and how the color of colored glaze is formed.
Like blue, blue is also the basic color of colored glaze, and it is also a more widely used color.
The color system is stable and there is little color cast.
Its main component is cobalt trioxide, which is an inorganic compound and a black oxide of cobalt.
It is generally used for coloring glass and ceramic products, which is also known as cobalt blue.
Dark green is rarely used in conventional gifts, and is generally used by some masters in art ornaments.
The amount of this stuff is relatively small, but each piece is high-quality, and its only ingredient is nickel trioxide.
Finally, there is purple. The saying that purple has a romantic color has become more commonly used in recent years.
Purple uses manganese dioxide, and generally the price of purple is slightly more expensive.
Obviously, the color ruby red is very rare even among glass products.
After all, this kind of thing is unstable. If you want to make red, once the color is prepared, it really depends on luck whether the final colored glaze is ruby red.
Therefore, Chen Wenzhe has a special advantage when making ruby red colored glaze.
Because he can cheat, he can easily do things that others cannot do by learning from the experience of his predecessors.
