What type of material is characterized as being unrefined and unfired in ceramics?

The type of material characterized as being unrefined and unfired in ceramics is greenware. This term refers to clay objects that have been shaped and dried but have not yet undergone the firing process in a kiln. At this stage, the clay retains moisture and is still fragile, making it susceptible to breaking or deforming if not handled with care.

In contrast, porcelain, stoneware, and earthenware are types of clay bodies that have been fired at various temperatures and thus are no longer in their unfired state. Porcelain is known for its fine texture and durability, while stoneware is typically more robust and suitable for functional ware. Earthenware is distinguished by its porous quality, usually fired at lower temperatures but still not in an unfired state like greenware. Understanding these distinctions is crucial in the study of ceramics and the processes involved in creating ceramic works.
