What Are the Stages of Clay? Our Pastimes

2017-9-15  Clay is in the bisque, or bisqueware, stage after it has been fired in a kiln once. It is still porous, but cannot become soft again if water is added to it. No additional clay pieces are able to be added to the design after it's been fired once. The firing of the kiln fully hardens the clay and this is the time when the sculpture can be glazed.

11.25 Clay Processing - United States Environmental ...

2015-9-10  Fire Clay -Figure 11.25-4 illustrates the process flow for fire clay processing. Mined fire clay first istransported to the processing plant and stockpiled. In some cases, the crude clay is weathered for 6 to12 months, depending on the type of fire clay. Freezing and thawing break the material up, resultingin smaller particles and improved plasticity. The material then is crushed and ground. At this stage inthe process, the clay has a moisture content of 10 to 15 percent. For certain applications, the clay isdried in mechanical dryers to reduce the moisture content of the material to 7 percent or less.Typically, rotary and vibrating grate dryers fired with natural gas or fuel oil are used for drying fireclay.

The Firing Process for Making Ceramics

2019-10-27  Firing is the process of bringing clay and glazes up to a high temperature. The final aim is to heat the object to the point that the clay and glazes are "mature"—that is, that they have reached their optimal level of melting. To the human eye, pots and other clay objects do not look melted; the melting that occurs is on the molecular level.
