Abstract
Disclosed is a shaped article made from concrete, artificial stone, ceramic, metal, plastic, etc. and having a minute and beautiful pattern expressed on part or all of the surface thereof by a pattern course of a prescribed thickness. This shaped article is produced by forming at least two superposed courses of different dry particles on a base surface, moving a scraper located at a prescribed position above the base surface in accordance with a pattern to be expressed so as to scrape at least the lowermost course, allowing the dry particles of the upper course to cave into a cavity thus formed, thereby expressing the pattern on the bottom surface of the lowermost course, and allowing all the particles to set into an integral mass, either as they are or after the top surface of the uppermost course is made even or overlaid with a backing course.
