The glass matrix, which occupies the majority of the molded body, is rich in SiO 2 and has excellent chemical corrosion resistance.
Since the molded body has many glass phases, it has good translucency.
A beautiful pattern is formed by a synergistic effect such as the incident light reflection phenomenon in the grain boundary region of the fused glass frit and the good diffusibility of the coloring pigment. Since the molded product contains a large amount of glass, various curved products can be easily molded in the heating and softening temperature range. Further, since the fusion property is good, it has a feature that a molded product in which glass frits of other composition are integrated and integrated can be obtained. Furthermore, the composition content is a large amount of SiO.
Since 2 is acceptable, 70% by weight of general-purpose glass such as float glass, bottle glass, and opalescent glass is contained in the raw material.
It is possible to mix up to, and contribute to the utilization of resources by recycling glass.

The crystallized glass of the present invention has a symbiotic structure of diopside crystals and calcium silicate crystals, and imparts high strength to a molded body with a large amount of glass due to the aggregate effect of needle-shaped crystals. are doing. The glass matrix with a high content of silicic acid is chemically stable and has excellent acid resistance. The molded product has a large light-transmitting property, and can form a brilliant appearance in comparison with conventional crystallized glass due to interactions such as light interference of crystals, reflection effect of a microcrystalline film at grain boundaries, and diffusion of coloring pigments. . The composition of the crystallized glass of the present invention is about 70%.
It has the feature that general glass materials can be blended.
This feature can greatly contribute to resource recycling of float glass, bottle glass, fluoride glass, and the like. Further, it is possible to perform fusion-bonding with general glass integrated products or glass of other materials which have similar thermal properties in terms of material, and to provide a beautiful artificial stone material economically at low cost.
