Marbled papers are among the best known decorated papers. In a shallow tray, solutions of pigments are sprinkled onto the surface of a watery substance, traditionally an extract of Irish moss. Using combs or other pointed implements, the marbler then works the colours into different patterns. Then a sheet of paper is carefully put onto the surface of the tray from one of the corners. When it is lifted again, the pattern has been transferred to the sheet.
