'''Ganghwa Girls ' High School's Global Issues Forum Camp English essay'''

During the first semester, I researched about Goryeo in a club under the theme of 1,100 years of the foundation of Goryeo. My mind got more complicated as I studied more and more, so I had to take time to organize what I knew. It is important to know, but it is of no use if it is not sorted out. Then, I learned about the activities in global camp. It was an activity to research, debate, and post materials. I thought learning what I didn't know was a good chance and I can tell others what I know so I decided to participate in a global camp. I usually have a quiet personality. However, I am playing the role of a team leader because I wanted to work on my own as much this time. Being a leader of the team, my teacher often called me and I had to have a meeting often, so it was a little overwhelming at first. But I became more interested in the camp.

My future dream is to be a researcher. Researchers conduct research based on existing data. I also chose chemistry as the topic because I wanted to study the celadon of Goryeo and study on the non-acquired colors that have not yet been identified. Before the camp, gunpowder was the only relationship I knew about the chemical. But this time, I learned something new by choosing an unknown field, Goryeo celadon. It was possible to complete the technique 1,300 years earlier than in China, although we were able to encounter the Goryeo celadon skill later. And there are more than four ways to make celadon, as well as the inlay technique we usually know. Also, the blue color of Goryeo celadon is said to be the use of oxidation, reduction reaction, which made me more interesting to learn chemistry.

The ability that I get most from the camp activities is cooperate with my colleagues. Unlike the usual data research, we worked with each other by helping and encouraging each other. As a result, I, who liked to do things by myself, enjoyed activities with my team. These changes will also help me later in my life. The activities with Wiki page and the team organizing things that I know and don't know give me a clear reason to participate in the global camp again next semester.

='''Goryeo celadon'''=
==Origin of Goryeo celadon==
The Goryeo celadon that we talk about as an art piece is a porcelain made of clay and coated with glaze and baked over 1,300 degrees Celsius. In China, jade symbolized a man of virtue and used it as a burial object, believing that it meant eternal life and drove out demons. At that time, the ruling class had many desires for jade and many people wanted to bury jade in their parents ' graves. However, the jade production was so small that they tried to turn precious jade into clay during the period. In Korea, Chinese celadon has been found in ancient tombs between 4 and 6 C, which can be found by importing Chinese celadon as royal jade. The color of Goryeo celadon was an advanced technique 1,000 years ago. In the 3rd and 4th centuries, China created a yellow celadon from Wolju Gama, and was not until the 9th century that it produced perfect celadon. The Buddhist Zen sect, which was widely practiced in China around the 9th century, began to use Goryeo celadon as a tea cup as its practice, as the habit of drinking tea to clear one's mind while meditating. The Chinese made perfect celadon, then the Goryeo people back-track it and created the Goryeo celadon at 11C. Chinese celadon is in its heyday during the reign of Emperor Huizong in 12C, and Goryeo celadon also hits peaks in 12C. We traced the celadon from 1,500 years of study by the Chinese and created it in 200 years. Afterwards, excellent Goryeo celadon started to be produced in Gangjin, Jeolla-do, and Gochang, looking for high-quality soil. In the beginning, Goryeo celadon is usually brown and is made of neat, intelligent, and neat celadon, but in the 12th century, it has been painted with patterns. At that time, the world of Goryeo people was a Buddhist world. They held their hearts in the Goryeo celadon and prayed for eternal world. For example, they used ponds, a world of Buddhist virtues, willow trees, ducks playing along the water, and wild flowers that showed silence and silence. This is why Goryeo celadon, which contains hundreds of years of desire for life, created the most beautiful pottery in the world.

==Techniques used in Goryeo celadon==
● Sanggam technique (상감기법)

The Sanggam technique is to dig a pattern using a sharp carving knife, and then to express a painting with mud deposits on the brush by using a method that can fill the part with more colored mud. Clay shrinks as the moisture evaporates, so it is often formed by the contraction of the other colored soil in the based soil and the intaglioed based soil.

● Intaglio relief technique (음각, 양각 기법)

It is a technique to make a shape of a vessel and dig out a pattern with a fine line before the soil dries, or bend the outer edge of a pattern to show off the pattern. It is the most basic technique from around the 11th century to the end of the Goryeo Dynasty, getting out from the early stage of the production.

● Ron-brown underglaze on white slip and Underglaze slip techniques (철화, 퇴화 기법)

Ron-brown underglaze on white slip and Underglaze slip techniques are techniques that express patterns in a manner that looks like paint on the surface of a baked vessel. The section of the finished product has a layer of earth patterned over the based soil layer, and then a layer of organic material overlaid on top of it, divided into iron oxide and degeneration according to the color of the painting. Ron-brown underglaze on white slip technique is known as iron oxide when it is painted with a black pattern on it. Underglaze slip technique refers to a technique in which patterns are drawn in black and white in the finished product, using red and white soil containing little iron.

● extrude relief technique (압출, 양각 기법)

It is a technique that pushes a properly dried bowl into a frame carved with the pattern of the bowl. This technique let pattern stand out. It can saves more time than carving out patterns one by one, and produces more vessels of the same type. The vessels are usually of many types suitable for printing, plates, and whole, and are usually patterned on the inner surface of the vessel.

● copper oxide Technique (동화(산화동)기법)

oxidized copper is also called jinsa. This is because when you burn it with reductant, it becomes red. However, it is very difficult to make red because copper oxide is very unstable depending on conditions such as temperature control and fuel supply. The copper oxide is expressed only in parts such as the buds of flowers and the edges of petals with an inlaid technique. There are also a few techniques made by painting the front of the bowl with copper oxide.

==Found Goryeo celadon==

[[File:청자순화4년명호(사진).jpg|thumbnail|Celadon with ‘淳化四年’Treasure number 237 <ref>한국민족문화대백과 http://encykorea.aks.ac.kr/Contents/SearchNavi?keyword=%EC%B2%AD%EC%9E%90%EC%88%9C%ED%99%944%EB%85%84%EB%AA%85%ED%98%B8&ridx=0&tot=4911#</ref>]]

This is a celadon pot with ‘淳化四年’ made in 993 years by the late 10th century, when Goryeo began to make the celadon pot in earnest. It is difficult to see it as a celadon, because it is yellow in color and the glaze is not completely dissolved and is running down. It was used in the shrine of Taejo of Goryeo as it was a highly developed listener in 993 years. Unlike a gas kiln, the success rate of the kiln at that time was less than 20 percent, and we can know how many failures there were through 10 to 15 meters of sediment found in the celadon pot.

'''A Growing Me With Global Forum Camp'''

2018 Global Forum Camp! I am now attending English camp which is held even during the short 2 weeks of summer vacation. Some of my friends halted me for doing it in only two weeks of summer vacation. Then, I told them firmly. " I have never missed a camp. The more I went to camp, the more confidence I have in speaking English. I couldn't say a word at first, but I did a little at the second time. Therefore, I will talk to my teacher in English a lot this time! " Then added “My friends♡, Let’s go together!” As a result, now I am participating in the camp with my friends, and this time I decided to challenge myself to speak English with my teachers.

My topic in this camp is investigating the chemical principles of the color of Goryeo celadon. Someone can say, 'um..?' for this topic. However, we talked about the topic on the 1100th anniversary of the foundation of Goryeo, I was very curious to hear about this topic and it's an amazing subject. Actually, I did not know much about Goryeo celadon. I only knew that the colors were so pretty and wonderful and enemy take the pottery makers with them during the war. Anyway, as I searched with my friends, I found out that the colors of Goryeo celadon use oxidation and reduction reactions. Know-how to make a celadon was a secret, so now there is no way to know. It was regrettable that we had to figure out a way to make beautiful Goryeo celadon, not just like the old one. However, it was a great try to find the way to make things in history step by step with advances in technology. I also wanted to develop and discover something that would help people.

I am so happy and easy to find the article on the first base of our group in a short time. Anyway, it was a good chance to learn English as well as Goryeo celadon, learn many things together. Also, I like to learn new things, this is the first time I have learned how to sign up for the wiki and tried to upload it by myself. I thought I'd like to upload other things that I'm interested in. This is very amazing experience to me. At this 2018 Global Forum camp, I became a strong person, because I have less fear of speaking English and being courageous than before. I hope I can become a growing person by trying many things to learn new things.
