The bone dry stage is when the moisture is out of the clay, and it's dry enough to bisque fire. This process can take at least a week or even longer, depending on the climate you live in. If it is very humid, you have to exercise patience.

Drying can be speeded up by pre-heating the ware in the kiln to 176°F (80°C) for a few hours. This part of the firing, up to 212°F (100°C) is called water smoking, which causes the water in the pores between the clay crystals …

Even if the clay is totally dry, it is important to use a kiln-drying cycle before the true firing begins. The key is to raise the temperature gently and hold it as long as necessary at 180°F to 190°F (82°C to 88°C).

Drying clay is always accompanied by shrinkage. As water leaves, the particles move closer together. Fine particle clay shrinks more than large particle clay because of the presence of more water. Drying shrinkage is always related to the grain structure of a clay and also to plasticity.

There are 3 main stages of firing clay. The first stage is the drying process. Clay needs to be bone dry before it's fired. The second stage is bisque firing. During the bisque fire soluble greenware clay is transformed into ceramic material. The third stage is the glaze fire. Each of these processes is important. So, let's take a closer ...
