The Firing Process for Making Ceramics

The bisque firing continues until the kiln reaches about 1730 degrees Fahrenheit. At this temperature, the pot has sintered, which means it has been transformed to the point that it is less fragile while remaining porous enough to accept the application of glazes. After the desired temperature has been reached, the kiln is turned off.

The cement kiln

The heating process is efficient because the meal particles have a very high surface area in relation to their size and because of the large difference in temperature between the hot gas and the cooler meal. Typically, 30%-40% of the meal is decarbonated before entering the kiln. A development of this process is the 'precalciner' kiln.

Figure 1: Brick making process 1.2 Firing process in the kilns Firing is the last operation in brick making process. Green bricks are fired in the kilns to convert a fairly loosely compacted blend of different minerals into a strong, hard, and stable product i.e. fired brick. The firing process determines the properties of the fired brick —

What Is Kiln Drying? The Reasoning Behind Drying Wood

The Kiln Drying Process. When trees are felled and brought to a lumber mill, the first step is usually to debark and sort the logs by species, size or by end-use. Logs destined for wood flooring, for example, are then sawn into rough boards of the required dimensions. These are often edged or trimmed for length before they are dried.

During the candling process, the lid of the kiln is propped open an inch or so with a kiln brick. This allows any moisture to evaporate out of the kiln. For the same reason, the peepholes, also known as spyholes, on the side of the kiln are left open. As an alternative to candling overnight, a lot of potters will do a 'pre-heat' in the kiln.

A kiln should be aligned when it is in operation for four very important reasons: 1. A straight cold kiln has a measurable misalignment at operating temperatures. This is because the shell axis elevation increases by one half of the thermal expansion of the shell diameter. This expansion is the function of the shell temperature and, as such, it
