Which term describes a low-fire clay that is porous and must be glazed?

Explanation:
Low-fire clays like earthenware stay porous because they don’t vitrify completely when fired. That porosity means they absorb water unless a glaze is applied, which seals the surface and makes the piece watertight and usable. Firing is the heating process itself, bisque is the first fired stage before glazing, and chroma relates to color—not a clay type. So the term that best fits a porous, low-fire clay that must be glazed is earthenware.
