Large jade polishing
There were two main polishing methods for large jade articles: - ** Hand Toss **: - First, he used an electric tool to install a diamond drill bit to decorate the jade piece, and then he used a diamond file to repair it carefully. - Using 600# - 1200#polishing sandpaper, a large area of grinding was carried out with round sandpaper (from coarse sand to fine sand). - Use a circular cloth wheel to apply polishing paste to polish a large area, and then use a felt grinding head to apply polishing paste to polish the details. You can also use a rubber grinding head to polish directly. - Finally, it was hand-processed with 1200 sandpaper and then polished with diamond powder. - ** Machine Throwing **: - Buy a small jade jewelry barrel polishing machine for 300 - 500 yuan. - Buy Feizhan's 320# - 8000#emery from rough polishing to fine polishing. At the same time, you can buy triangular bead polishing particles, cold light powder, grinding polishing powder, etc. to polish in the polishing machine for a period of time to achieve a mirror effect. Different types of large-sized jade, such as jade, had a special polishing process: - ** Jade **: - Roughly grinding: Use (1000 - 2000 mesh) emery to make tools of various shapes and carefully polish them smooth. - Fine grinding: Use (1600 - 1800 mesh) emery to continue grinding according to the rough grinding method to make it smooth and shiny. - Bright: Use half-lived cowhide production tools to dip in polishing powder (3.5 um diamond powder) and rub it repeatedly to make the jade products bright inside and outside. - Wax: To prevent water and dirt pollution. The process is to first coat the surface with a layer of pasty polishing powder (Green for Chromic Oxides, orange-red for Cerium Oxides), grind the surface with a 2,000-mesh grinding wheel, repeat it twice, then apply a brush, apply the diamond powder on the surface of the jade, and then use a hard brush to polish it. Fine work, start to polish the small places that the big tools can't reach.(Use bamboo chopsticks for bigger ones, bamboo toothpicks for smaller ones, and dip them in diamond powder). Then, use the hard skin to polish it, then use an ultrasonic machine to clean it. Use alcohol to wipe the areas that can't be cleaned, then wax it. Finally, wash off the wax with boiling water and dry it with a hairdryer. Some details should be paid attention to during the polishing process. For example, for large jade articles with a certain hardness (such as Hetian jade), different types of oilstones should be used to polish them a little along one side. At least three types of oilstones should be used from coarse to fine. After the oilstones are polished, there should be no traces of knife marks. Then, the machine should be used to polish them with cowhide or cotton cloth wheels (cowhide throws strong light, cloth wheels throw soft light). Before polishing the cowhide or cloth wheels, it must be polished with oilstones. Otherwise, the effect will be poor and it will be troublesome to redo. Read more exciting novels for free

College Star's English Essay
The following is an example of a college English essay about a celebrity: **Title: Stars - More Than Just Glitter** In modern society, stars play a significant role in various aspects of our lives. They are no longer just individuals with extraordinary talent in the fields of acting, singing, or dancing but have become cultural symbols with a far - reaching influence. Many stars are multilingual, especially in English. For instance, some Chinese stars who have studied or worked abroad, like Li Yifeng, can communicate fluently in English. Their language ability not only helps them in their international career development but also sets good examples for their fans. Stars often participate in international events, such as film festivals or music awards. At these occasions, their proficiency in English enables them to better represent their countries and cultures. However, the star - worshiping phenomenon among college students also has its two sides. On one hand, positive stars can inspire students. Their hard - working stories in achieving fame, like how they overcame difficulties in learning languages and cultures, can encourage students to pursue their dreams tenaciously. For example, when a star shares his or her experience of learning English from scratch, it may motivate students who are struggling with English learning. On the other hand, excessive star - worship can have negative impacts. Some students may focus too much on the appearance and luxurious lifestyles of stars, ignoring their own studies and personal growth. In the context of English learning, instead of concentrating on real language skills improvement, they may only be interested in the English - speaking skills of stars for the sake of idol - worship. In conclusion, stars are an important part of our cultural landscape. College students should view them rationally, learn from their positive qualities, especially in aspects like English proficiency and the spirit of hard work, while also not being overly influenced by the negative aspects of star - worship. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
