“Feldspar is not a familiar rock, the way granite and limestone are, but it is a large constituent of all igneous rocks, those produced under extremes of heat and pressure, and when feldspar disintegrates, because of pressure or because of erosion by air or water, it largely turns into clay. Clay has been used since time immemorial to make all our bricks, tile and pottery that largely make human life possible through the combination of clay, fire and desire. It was from a divine version of this material that God made the human body, as many people believe. The mundane material, clay, as the basis of human culture.”
