content: FROM CARD: "FINE CLOSE-GRAINED PEBBLES OF QUARTZ AND CHALCEDONY, WHICH SHOW THEIR ARTIFICIAL USE BY HIGHLY POLISHED PARTS. THESE CLOSE-GRAINED PEBBLES ARE USED FOR THE POLISHING OF THE CLAY SURFACES OF POTTERY, WHICH IS ACCOMPLISHED BY GRASPING THE STONE IN THE TIPS OF THE FINGERS AND THUMB, AND WITH A RAPID RECIPROCATING MOTION RUBBING THE FACE OF A VESSEL UNTIL HAS TAKEN A HIGH GLOSS. THIS POLISHING INCREASES THE HOMOGENEITY OF THE WARE AND REDUCES THE DANGER OF BREAKAGE IN FIRING. WHEN THE WARE IS PAINTED RED A SECOND POLISHING IS RESORTED TO AS SOON AS THE RED OCHER SLIP HAS DRIED IN."
