Adi gets off the bus along with Satya. Where Ro, Rey and Thunder were already looking for them in the crowd. To enter mated see ceramics inside.”Why did you guys take so long,”ucap Thunder.
“Sorry I woke Adi up first. We're in now, no assignment from the supervising teacher,”ucap Satya.
“Who says no. It's what,” said Rey.
“So there are tasks that we have to do yes,”ucap Satya.
“Iya. But we were only given one problem. The process of making ceramic from clay only,” Rey said while reading sheet of paper.
“Ya we have entered now just let us finish quickly and can go around,” Adi said. They all disturb and walk towards a temple where the process of making ceramics is made. Which in front of them was another group heading for first place.
“We go first or just relax this time. Looking at those pale y'all,” said Thunder.
“As usual,”ucap Roy.
“You don't mind Adi,”ucap Roy again. Adi just shook his head if he was okay. After deciding they walked first where they saw where the first material was found.
The defensive material used in the process of making caramics from clay is the clay itself. These special characteristics include being clay or sticky, difficult to absorb water, and can be split into fine grains when dry. Some of these characteristics make the clay become easily formed and created according to your wishes.
Soil formation without a turning table can be done using massage techniques, spin techniques, and slab techniques. While the rotary technique is done on the turntable, either manual or electric. The formation of soil through the printing technique is done by printing the soil in a mold that is usually made of casts or silicon.
After the formation process is complete, the next stage is the drying process. It is best to dry by using natural wind or outdoor drying in the sun. It takes at least 3 days for the natural drying process.
The next process is combustion, this process is done so that the originally fragile ceramics become solid, hard, and strong. Factors affecting combustion results include mature temperatures, furnace atmospheres, and the minerals involved. The raw ceramic materials are then put into the combustion furnace and burned using a temperature of about 700-1,000 degrees Celsius.
The process of grinding is to protect the ceramic, strengthen the structure, and beautify its appearance. The application of this glaze material can be done by dyed, sprayed, poured, or polished with a brush onto a ceramic surface evenly. The function of glazing on ceramics is to add beauty, so that it is more watertight, and add certain effects as desired. Finally, the ceramics that have been glazed need to pass through the glaze combustion stage first to complete the result.
“Tadi is not made of clay. But there are how many types of clay that can be used in the manufacture of scallops,”ucap Roy.
“I don't know. Kind of clay there are several types that I know of. But every country will use clay differently,” Satya said.
“Adi you know not the kind of clay that can be used,” Rey said.
“You don't know. Why don't we just ask the ceramic craftsman to add our ilu,” Adi said.
Kaolin Clay is known for its mineral purity, Kaolin Clay has a bright color that is very often used for porcelain in Chinese/Chinese culture. Although kaolin clay does have some color variations, it is very light in color. When moist, they will be light grey and will light up in the range between gray or white. It is also called White Clay. White clay is often used in the manufacture of cosmetics in the cosmetic industry.
Ball Clay or Clay Ball has very little dirty minerals, so it can not be used alone because of its excessive shrinkage during drying and burning at temperature 1285 ℃. They are very useful, however, when added to other clays to improve the workability and plasticity of Ceramic dough. Due to its high plasticity and high binding quality, Ball clay is commonly used for floor tiles, toilet bowls, flower vases, and cutlery.
Fire clays are a type of clay that has a high refractivity of 1,600 °C and is suitable for use in fireplace construction, firebox, and other applications that require high temperatures such as the Metal processing industry. It usually consists of kaolinite, halloysite, and other minerals that provide good heat-resistant properties. Fire clays are also often used in the production of ceramics and other materials exposed to high temperatures. It is found in various locations around the world and can be processed to produce different types of fireproof clay products.
Stoneware Clay is a fairly plastic Clay, hard, and not porous almost like a rock. Getting its name because of its quality that is like a stone. Stoneware clay is mostly clay-ball based, not and not kaolin-based. In addition, like Fireclay, Stoneware Clay also has a high hot spot that is 1100 to 1200 ⁰C. Stoneware Clay became a popular clay used for tableware such as Pot.
“It turns out there are 5 types of clay that can be used,”sata Satya.
“Now we already know 5 types of that land. If later we want to make an item from clay,” Adi said.
“That's true but not the making step is quite difficult isn't it,”Guntur said as he scratched his cheek.
“Not really if we want to make it,” Rey said.
“It's true, it's just now what time it is. We collect what time,” said Adi.
“For today we gather at three in the afternoon. After that we will eat together before going to the hotel,”kaa Satya.
“Eat what this time,”ucap Guntu.
“It is written typical food area here,”sata Satya.
“So we culinary eat after this,”kata Adi. Satya nodded her head. After they finished asking, they went to see what crafts they could make souvenirs.
“I think there is a place for us to buy souvenirs from clay. We go there yuk,”ucap Satya. They went to the place where Satya went, where the teacher and other students also went to buy ceramic souvenirs from clay.
Adi who saw from plates, vases, glasses, carvings with different shapes. Until Roy who is behind him also pays attention.”Do you like Adi,” Roy said.
“I don't think there's a brother. But mama roughly likes not that if we buy a vase that mingles with the two colors,” Adi said while pointing to the array of red vases mixed with white that blend with each lin.
“I think mama will like,”kata Rey walks over.
