Introduction to Porcelain
This course is an introduction
to the material - porcelain clay. You are required to have experience of working
with other clay sorts before you can enroll on this course.
Studying the basic
techniques enables one to make creative designs. The last
two or three lessons are used to make glazes such as
temoku, as well as traditional Japanese and Chinese
glazes for a special ´reduction´ firing in the kiln.
Porcelain is a
ceramic material made by heating raw materials,
clay in the form of
kaolin, in a
kiln to temperatures between 1,200 °C and 1,400 °C. The
toughness, strength, and translucence of porcelain arise
mainly from the formation of glass and the mineral
mullite within the fired body at these high
temperatures. Porcelain is sometimes referred to as china.
This is because until the 17th century, China was the sole
producer of porcelain.
