Whether or not gilding products were harmful to the body could not be said to be the same. For the gilded tea set, when the trace mercury content was relatively low, it usually did not have a significant impact on human health during normal use. However, some metal components contained in the processing may be unstable after long-term use, which may cause irritation to the health of the body and cause discomfort in the digestive tract, such as abdominal pain and diarrhea. For gilded jewelry, although highly toxic mercury would be added during the production process, the toxic substances were volatile and would not cause substantial harm to the human body.

In metalworking, it was usually called " gold gilding." Gold gilding was a traditional metal decoration technique that had been produced since the pre-Qin era. It was also known as fire gilding or mercury gilding. It was to synthesize gold and mercury into gold amalgam, apply it to the surface of a bronze ware, and then heat it to evaporate the mercury, so that the gold would adhere to the surface of the ware. " Gold-plated " might be a misrepresentation of " gilded ", and there was no such formal saying in the context of metal craft decoration. The novel " Gilded Palm " is equally exciting.

To a certain extent, gold-plating and gilding were the same. In terms of word class, gold-plating was a verb, which referred to the traditional art of applying gold dissolved in mercury on the surface of an object to decorate it. Gold-plating was a verb and a verb. When used as a verb, it was the same as gold-plating. It referred to the traditional art of applying gold mud made of gold-mercury alloy on the surface of the object, and then baking it to evaporate the mercury and let the gold be fixed on the object. When used as a verb, it referred to gold with good color. The two words are inclusive,"gilded gold" includes "gilded gold", and the pronunciation of gilded gold and Lu is synonymous,"gilded gold" can also be used as "gilded gold". However, in order to make the meaning clear, the two words should be treated separately: when it refers to good quality gold,"gilding" is the recommended word form, while "gilding" can refer to traditional gilding methods.

Gold gilding and gold-plating were essentially the same process. The first step was to prepare the gold amalgam. First, the gold had to be thinned and cut into pieces, then placed into a pre-heated crucible, and then injected with mercury. The ratio of gold to mercury was 1:5 - 1:7, so that it was mixed into a paste. During this process, the surface of the object needed to be cleaned with an acid and base solution. Then, it was time to apply the gold. The gold amalgam was evenly applied to the surface of the object (such as bronze). Next was to crack the gold. By baking the plated object, the mercury would evaporate and the gold would remain on the surface of the object. Finally, it was calendering to make the coating more dense and bright. When the operation was done, the color of the coating could remain unchanged for a long time. This kind of craft could be used to decorate building components such as copper and iron and various utensils. In ancient times, apart from being used on the surface of utensils, it was also used to gild weapons. The entire process usually needed to be repeated about three times, but to achieve a better gilding effect, it was common to repeat it five to seven times.

Gold gilding was a metal processing technique. It was to apply a gold mercurial agent composed of gold and mercury on the surface of a bronze ware. After heating it up, the mercury would evaporate, so that the gold would firmly adhere to the surface of the bronze ware and not fall off. Gold was used in the gilding process, but because it formed a gold layer on the surface of the object, it was not a pure gold product, but an object decorated with a gold layer on the surface.

Gold gilding usually only required a few dozen grams of gold, but the exact amount would vary depending on the size of the object, the number of layers of gold gilding, and other factors. For example, the gold-plated bronze lions in the Forbidden City had been gilded five times, using more than 330 taels of gold. The novel " Gilded Palm " is equally exciting.

Bleach is harmful to the human body. The main component of the bleacher was a strong disinfectant, which was corrosive to the skin and digestive system. Contact with bleaches can cause skin corrosion and burns, causing contact and peeling dermatitides. Eating bleaches by mistake could cause damage to the digestive system such as the esophagus and stomach, and even cause bleeding. The toxic components of the bleacher could also damage the liver and kidney function and even lead to failure. Wear a mask and gloves when using the bleacher, and dilute it before using it. Try to reduce exposure to bleaches and choose a mild shampoo to wash clothes to reduce damage to the skin.
IT work was harmful to the body. First of all, IT workers often sit for a long time, which will affect the heat dissipation of the Scrotum, causing the temperature of the Scrotum to rise, which in turn affects the ability of the testes to produce sperm. Long-term exposure to electronic radiation such as computers will also affect the sperm production of the testes. Secondly, sitting for too long would cause the Prostate to be oppressed, and the secretion of the Prostate fluid would not be smooth, resulting in stagnation. Holding back the urine would increase the pressure on the ureter, causing urine to flow back. Drinking less water would cause the urine to concentrate, and the increase in storage time would easily lead to infection. These were all predisposing factors for Prostatectomy. Prostatectomy could affect the amount and composition of semen, interfere with the survival and activity of sperm, reduce the activity of the zymes in the Prostate fluid, increase the semen's stickiness, and prolong the sperm's liquification time. It may also cause the semen to lower the pH value and produce anti-sperm antibodies, resulting in sperm death. In addition, IT work with excessive eyes, long-term focus on the screen, lack of sleep, heavy pressure, etc. will lead to headaches; less exercise, high pressure will make muscles tense, poor blood circulation, muscle capillaries form blood clots, which can cause neck and shoulder pain; Female IT workers are more likely to suffer from low back pain due to the heavy burden on the spine. In short, IT work had many harmful effects on the body in terms of reproductive health and pain. " When a programmer meets a psychologist " is equally exciting.

Gold gilding and gold plating had their own characteristics and had different practicality in different application scenarios. In terms of process complexity, the gilding process was more complicated and cumbersome, while the gilding process was relatively easier to operate and more versatile. If it was an object with a complex shape and high precision requirements, gilding might be more practical because it could gild a very detailed process, and the gold layer after gilding was relatively thick. In terms of durability, the gold-plated layer had the advantages of anti-corrosion, wear resistance, high temperature resistance, etc., but the gold layer was often thin and easy to fade, while the gold-plated layer adhered firmly to the object and was not easy to fall off. If the durability of the object was high, gilding might be more advantageous. From the perspective of environmental protection and health, the gilding process required mercury to make gold mud. Mercury was a toxic substance, which might affect the health and safety of non-hereditary inheritors during the operation. The addition of cyanidation in gold-plated gold water was also dangerous, but relatively speaking, modern gilding technology might be easier to control under environmental protection and safety management, which would affect its practicality in some scenarios. From the perspective of historical inheritance and artistic value, gilding had a history of more than 2500 years. It was a very ancient metal craft technique in ancient China. Gilding on historical relics and traditional crafts could better reflect its artistic value and cultural heritage. Gilding only had a history of more than 100 years, so it might be more practical in modern industrial production of decorations. In summary, it was impossible to simply determine which was more practical, gilding or gilding. It needed to be considered based on the specific purpose of use, environment, culture, and many other factors. The novel "Gilded Palm" is equally exciting. Everyone is welcome to click and read it!
Listening to books itself would not cause direct harm to the body, but if one was overly focused while listening to books, it might cause some side effects. If you are exposed to noise for a long time while listening to a book, it may cause hearing damage. If you use the wrong equipment when listening to books, it may cause eye fatigue or dryness. Smoking or drinking while listening to books may increase the harm to one's health. Therefore, when listening to books, you should pay attention to maintaining a good posture and volume and avoid excessive concentration.
The nature of a programmer's work and work habits did indeed have some elements that could cause harm to the body. From the perspective of body posture, writing codes for a long time for sitting for a long time may hurt the spine. Because of poor sitting posture, the lower back is suspended, the lumbar spine is in a state of fracture, the gravity on the disc increases, and it is easy to induce degeneration and protrusion of the disc. Long-term forward tilting of the cervical spine will increase the pressure on the cervical disc, stimulate the nerves around the shoulder joint, and cause scapular periapathy, resulting in limited arm movement and pain. In the early stage, there may only be dull pain or shoulder joint discomfort and restraint, and then the pain will gradually increase. At the same time, using the mouse and keyboard in a fixed position for a long time could easily lead to "mouse hand"(carpal tunnel syndrome). The ligaments and tendons in the carpal tunnel would swell. The narrowing of the carpal tunnel would compress the nerves, causing wrist discomfort. It could also cause tendon sheath inflammation, which was manifested as pain in the thumb and index finger, poor joint flexibility, and snapping. The pain and stiffness in the morning were more severe. In terms of eyes, programmers stared at the computer screen all day long, and their eyeballs were not moistened. In addition, they were in dry environments such as air-conditioned rooms for a long time, so their eyes were more likely to dry up. Even a night's rest could not relieve them. They might not be able to open their eyes, have red blood vessels, and other dry eye symptoms. In terms of health indicators, some programmers might have abnormal uric acid metabolism due to their busy schedule, lack of exercise, and irregular diet. For example, some programmers found that the joints on their hands were covered with stone-like lumps (tophus). This was the result of long-term lack of control of uric acid. If the uric acid was too high, it would cause the blood to not dissolve and condense into crystals in the joints and skin. If they did not pay attention, it might even cause kidney damage. In addition, programmers often worked overtime and worked long hours. If they did not get enough rest, did not exercise, and often stayed up late, the probability of sudden death would increase. However, as long as they maintained a regular lifestyle, persisted in exercising, and reduced staying up late, they could avoid such serious situations.
