What are the main applications of spirulina blue?
The color of snail green has many merits in various uses. Looking at the book "Tiangong Kaiwu", the use of this color involves a wide range of fields.
First, in the dyeing and weaving industry, snail green is a heavy material for dyeing. The dyer takes snail green and applies it to the fabric in a delicate way. The color of its dyeing is deep blue, like water in a pool, quiet and deep. On the silk silk and silk, the color of snail green gives it a different style, or as a robe, which is worn on the body, showing solemnity and elegance; or as a curtain, hanging in the room, adding a bit of quiet rhyme. And the longer the color is, the more mellow it becomes, unlike his color that fades easily, so it is favored by weavers and dyeers.
Second, on the road of painting, snail green is also valued by painters. The painter enters the ink with snail green and wipes it on rice paper. You can paint mountains and rivers, paint the mountains, the peaks and peaks contain green, just like Cuidai, with a natural tone; you can describe the forest springs, dye the forest leaves, lush and green, and the springs seem to contain blue and vivid. The color of snail green can help the painter outline the artistic conception, create an ethereal and distant painting, and make the viewer seem to be immersed in the beauty of the mountains and rivers.
Third, in the art of ceramics, snail green also has its uses. The kiln worker uses snail green as a glaze and applies it to the pottery blank. After firing in the kiln, the surface of the porcelain shows a faint blue luster, like the shadow of clouds in the blue sky and the light of the deep sea. Whether it is a bottle or a bowl, the snail green glaze color gives ceramics a unique beauty, which is both practical and ornamental. It adds a unique artistic charm to ceramics. Among many kilns, it is unique and cherished by the world.
To sum up, the color of snail green shows its unique charm in the fields of dyeing, weaving, painting, and ceramics, adding luster to all kinds of skills. It is really wonderful.
How safe is spirulina blue?
The blue of the snail octopus is related to safety, and this is a big deal. Take the "Tiangong Kaiwu" as an example. Although the safety of the blue of the snail octopus is not detailed, there are many insights into various creations and physical properties, which can be analyzed by side.
The snail octopus is the egg sheath of the mantis, and its color may be different from ink blue. For most natural things, its color is often related to its environment and its own characteristics. In ancient records, snail octopus is used as medicine, which has the effect of fixing essence and shrinking urine, nourishing the kidney and helping yang. The color is ink blue, either because of the mineral infiltration in the environment, or because of its own special composition.
If it is about its safety, the first thing to look at is where it grows. If it is born in a clean place, it is less polluted, and its safety can be high. Gu Yun: "Those who are near Zhu are red, and those who are near ink are black." Things that are born in a clean place are less filthy and evil. And snail octopus is not only a place for mantis to raise children, but mantises choose a suitable place.
Check its composition for the second time. Although "Tiangong Kaiwu" does not say the cause and composition of the color of snail octopus blue, it is inferred that it is composed of natural substances. Natural things, if they are non-toxic, can be safe. Ancient healers used snail octopus to treat diseases, and some of their safety has also been verified by practice. However, the physical properties of the world are complex, or there are unknown ingredients, which cannot be completely determined.
Furthermore, observe its changes. If the blue object of snail octopus ink is exposed to temperature, water, light, etc., there is no strange change, no peculiar smell, peculiar color, and abnormal shape, then the stability is good and the safety is also increased. Ancient identification of objects often uses intuitive changes to detect their properties.
However, if you want to know the safety of snail octopus ink blue, it is still not enough to rely on ancient books. In today's world, science and technology are prosperous. We should use scientific methods to analyze its composition and structure in detail, and through rigorous experiments, we can understand its advantages and disadvantages in the human body and the environment. Although ancient wisdom can be inspired, scientific evidence is the right way to understand physical safety.
What are the advantages of spirulina blue compared to other pigments?
The blue color of Luo Wan is unique compared to other colors. The blue color is like the blue of the sky and the blue of the water, which has the charm of nature and has a quiet and peaceful state. Above Luo Wan, it is like a pool reflecting the sky, giving people a sense of distant and elegant.
Compared with the bright colors such as red orange and yellow, the blue color is less noisy and more restrained. The color of red orange and yellow is like the burning sun, dazzling and warm, but it is easy to get tired when you look at it for a long time. The blue color is like a clear spring in the mountains, babbling and flowing, and when you look at it, your mind is calm and calm, like a spring breeze.
Compared with black and white plain colors, although the two also have a simple and simple beauty, they are slightly monotonous. And blue adds a touch of agility to the simplicity, just like the faint blue in a black and white picture scroll, making the picture suddenly charming, just like hearing thunder in the silent place, and seeing beauty in the colorless.
Luo Wan valerian, when it is dyed, the craftsmanship is also unique. The craftsman carefully blends, so that the shade of blue is appropriate, which does not lose its freshness and elegance, but also has a sense of hierarchy. When it touches the body, it mirrors the skin, and the skin tone is more radiant and elegant. Walking, the blue Luo Wan dances lightly with the wind, like blue waves rippling, beautiful beyond words. Therefore, the blue color in Luo Wan, is really complementary to each other, compared to other color, unique this can lead to reverie, tranquility and far-reaching and highlight the advantages of smart.
What is the production process of spirulina blue?
Although the production process of blue-purple glaze is not specifically recorded in "Tiangong Kaiwu", with reference to the records of ancient glaze production and relevant knowledge, it is roughly as follows:
The production of glaze requires preparation of materials. Quartz sand is the main raw material, and it is necessary to select those with pure texture. It is also often accompanied by soda ash, limestone and other fluxes to reduce the melting point of quartz sand and make it easier to melt. And the ratio of raw materials is very important. Different proportions cause different colors and textures of glaze. To make blue-purple glaze, a specific proportion may be required, and copper, cobalt and other colorants are added.
Melting is a key step. In a special furnace, the raw materials are melted at high temperature. In ancient times, firewood and coal were used as fuel. After long-term high temperature calcination, the raw materials were fully reacted and fused into a uniform liquid state. This process requires extremely high heat control. If the temperature is too high or too low, it will affect the quality of the glaze.
When forming, when the glaze liquid reaches a suitable temperature and fluidity, the craftsman uses exquisite skills and special tools, or casts it in a mold, or uses a blowing method to shape the glaze liquid into the desired shape. This step requires skilled techniques and agile movements to ensure the molding effect.
The coloring process determines that the glaze appears blue-purple. Or add cobalt-containing minerals to the raw materials. At high temperature, cobalt ions interact with the glazed matrix to give a blue tone; or add copper-containing substances, and through complex chemical reactions, produce a purple effect. The ideal blue-purple can be achieved by a reasonable combination and precise dosage of the two colorants.
Then annealing. The formed glazed products need to be slowly cooled and annealed to eliminate internal stress and prevent cracking. Place it in a specific annealing kiln and gradually cool down according to the set procedure. After several hours or even days, the structure of the glazed glass is stable.
Finally, modification. For annealed glazed glass, craftsmen refine it by polishing, carving and other processes to make the surface smooth, add artistic beauty and details, and finally become a beautiful blue-purple glazed product.
