Rouffaer reported that the "gringsing" pattern was already known by the 12th century in Kediri, East Java. He concluded that this delicate pattern could be created only by using the "canting", an etching tool that holds a small reservoir of hot wax invented in Java around that time. The carving details of clothes worn by East Javanese Prajnaparamita statues from around the 13th century show intricate floral patterns within rounded margins, similar to today's traditional Javanese or batik motif. The motif is thought to represent the lotus, a sacred flower in Hindu-Buddhist beliefs. This evidence suggests that intricate batik fabric patterns applied with the "canting" existed in 13th-century Java or even earlier. By the last quarter of the 13th century, the batik cloth from Java has been exported to Karimata islands, Siam, even as far as Mosul.
