Abstract:
The present invention discloses a method for preparing a full-body marble-patterned glass mosaic, comprising mixing a glass powder with an additive to obtain a mixture; adding water to the mixture and mixing thoroughly; granulating and sieving to obtain base clay body powder; mixing a colorant and a flux according to a specific ratio to obtain a colorant mixture in powder form; distributing the base clay body powder and the colorant mixture into multiple layers via a mold; press-molding to obtain a clay body; firing the clay body to obtain the full-body marble-patterned glass mosaic. Accordingly, the present invention provides a full-body marble-patterned glass mosaic prepared by the method described above. The glass mosaic of the present invention has a strong layering texture and a well-defined structure, and it faithfully resembles the pattern and texture of natural marble.

Abstract:
A method of fabricating a randomly-colorized glass vessel includes gathering an initial gob of molten primary glass. A quantity of secondary-glass particles is introduced into the initial gob in order to form a particle-containing gob. The secondary-glass particles are made from a secondary glass that contrasts in color with the primary glass. The particle-containing gob is then heated sufficiently to melt the secondary-glass particles and create flows of the secondary glass within the primary glass. Once the desired flows have been created, the gob of primary and secondary glass is introduced into a vessel-defining mold. The mold is sealed and a quantity of gas is injected into the mold in order to form the gob of primary and secondary glass into a vessel.
Abstract:
A crystallized artificial marble is fabricated using incineration ash. In a fabrication method, incineration fly ash of 50 to 80 weight percent is mixed with SiO2 of 20 to 50 weight percent and additives of 0.1 to 3 weight percent for coloring, clarification, and reinforcing. The mixed material is melted at 1300 to 1500° C. for 0.5 to 1.5 hours and water-cooled to form granulation slag. Then the granulation slag is screened to separate fine particles according to size. After mixed with particulate, the granulation slag is deposited in a refractory die and heat-treated at 1000-1200° C. for about 1 hour or less and at 850-1050° C. for about 2 hours or less.
Abstract:
A crystallized glass-ceramic molded product having a glass matrix and crystallized calcium fluoride and fluormica dispersed therein. The molded product is prepared by mixing and melting together the necessary constituents for forming the glass, calcium fluoride and fluormica and rapidly cooling the melt to produce a frit. Particles of the frit or of two or more frits are then subjected to sintering and crystallizing heat treatments.
Abstract:
An inorganic pigment, the pigment comprising a compound which is an oxysulphide or oxyselenide of tin and a metal chosen from niobium or tantalum. The pigments are brightly colored in the color range from yellow, through orange to red, and are especially suitable for the coloration of glass and plastic substrates. Methods for the production of the pigments are also described.
Abstract:
A crystallized glass article having a surface pattern like granite, marble or other natural stones with a line pattern of a desired color or colors, which is formed by fusion bonding small masses of a crystallizable glass material mixed with inorganic pigment powder at a heat-treating temperature higher than the softening point. The surface pattern comprises crystallized glass areas defined by the small masses in the surface layer of the article and the colored line pattern defined by the pigment dispersed in the interfaces between adjacent ones of the small masses in the surface layer.

Abstract:
A glass includes a first glass portion and a second glass portion. The first glass portion has a higher ion packing density than the second glass portion (has a composition that forms a glass in which, out of plastic deformation characteristics, plastic flow is dominant). The second glass has a lower ion packing density than the first glass portion (has a composition that forms a glass in which, out of the plastic deformation characteristics, densification is dominant).
Abstract:
The invention relates to an arrangement of a furnace and of bulk material of glass particles, said furnace (10) comprising a pressing punch (36), a pressure, distance and/or speed sensor and a control device for controlling a pressing process based on the output signal of the sensor. The sensor detects at least a pressure, position and/or motion parameter of the pressing punch (36). The pressing punch (36) acts on the bulk material of glass particles (32)—possibly via an interposed ram (28)—, said glass particles being guided and crystallizable in a press channel (30). The trigger criterion for the process control is a change of at least a motion parameter of the pressing punch (36) upon softening of the bulk material of glass particles (32) which change is detected by the sensor.
