Abstract
A method of producing shaped articles of artificial stone, ceramics, metal, plastic and the like, each having a fine, attractive pattern on part or all of the surface thereof formed in a pattern course of a prescribed thickness. The shaped article is produced by forming a dry particle course on a base surface, positioning a scraper at a prescribed point on the base surface, moving the scraper in accordance with the pattern to be expressed, and using a different type of particles to fill the cavity thus formed by the scraper, and allowing the particles to set into an integral mass, either as they are or after being overlaid with a backing course.
