"Temperature Control" - anothor important factor in ceramic firing
Temperature control is another essential aspect of ceramic kiln firing. The kiln temperature must be controlled both when the kiln is firing and when the kiln is cooled as well as controlling the atmosphere of the kiln as needed by using the most economical fuel but getting the most heat. The temperature control factors are as follows :
- Understand the nature of kilns > Although kilns are built in the same method, no two kilns can produce the same result. This is because every kiln has its own variety and flaws. However, by firing vessels several times you will recognize its unique point that will help to achieve the same quality firing result.
- Temperature acceleration > The temperature in the kiln should be adjusted appropriately. Do not accelerate the firing and should not keep firing or stand on fire for a long time without adjusting the temperature because not only it wastes fuel and energy but also it changes the chemical reaction of the glaze and clay. The workpiece will then not be as beautiful as it should be.
- Setting the firing temperature > If the firing temperature is set too high, the glaze will flow more. Some types of glaze will flow greasily on the kiln shelves and the clay will swell. In extreme cases, the kiln shelves may distort or break down onto each other. The firing that does not reach the maturity, the container surface will be rough and the color will not be beautiful. However, firing below the mature temperature can be solved by bringing it to fire at the higher temperature again.
- Do not forget to record the firing > Record every firing no matter raw firing, glaze firing or firing on glaze in order to know which type of firing are successful or facing obstacles in order to study the problem and find a solution in the future. The advantage is that when the same container is needed again, it can be done by checking the firing log. Therefore, firing requires a lot of experience in order to improve and develop for better results. No matter how skilled or experienced potters are, they should still record it every time by writing them in text or plot points on the firing table.
