Abstract

The invention provides a crystallized glass product with pattern, which comprises: a crystallized glass layer A formed by sintering multiple small crystallized glass bodies and crystallizing them at the same time; and a crystallized glass layer B formed by arranging a crystallized glass plate B on at least one surface of the crystallized glass layer A while it is in sintering state, and crystallizing the crystallized glass plate B from surface to inner center. The primary crystallization of the crystallized glass layer A is at least one of beta- wollastonite, beta-CaO-SiO2 and diopside, CaO-MgO-2SiO2; while the primary crystallization of the crystallized glass layer B is is at least one of beta- wollastonite, beta-CaO-SiO2 and diopside, CaO-MgO-2SiO2. Besides, the invention further provides a manufacturing method of the crystallized glass product with pattern.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2007-187654 filed on July 18, 2007, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a patterned crystallized glass product and its manufacturing method, as well as its use in building exterior materials, interior materials, furniture panels, desk panels, and the like. Background technique [0004] In recent years, with the change of times, there have been increasing demands for various crystallized glass products such as building exterior materials, interior materials, furniture panel materials, and office desk panel materials.
