The dried roots of the tororoaoi [sunset hibiscus] plant are called nire. The nire is placed on a stone and beaten until it falls apart, then placed in a stone mortar with some water and worked with a pestle or mallet. The resulting sticky liquid [nirejiru] is collected in a cotton bag. This liquid is used in the vat when making paper. Nirejiru is a liquid with no smell or colour, is clear and slick.
