1826 results about "Ceramic glaze" patented technology

Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a ceramic body through firing. Glaze can serve to color, decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids, sealing the inherent porosity of unglazed biscuit earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain. In addition to their functionality, glazes can form a variety of surface finishes, including degrees of glossy or matte finish and color. Glazes may also enhance the underlying design or texture either unmodified or inscribed, carved or painted.

Phosphorescent blends

Self-glowing phosphorescent blends comprises of silicates, phosphate, and their compounds with aluminates (e.g. alumino-silicates and alumino-phosphate) phosphors are disclosed. These blends can be optically charged by exposure to sunlight or artificial light sources, and are able to emit visible light for hours in darkness without the need of electricity or consumption of materials. Such optical charging-discharging cycles can be repeated at least 1000 times. These blends can be used to form many commercial products and used in many applications such as: self-glowing paints or coating blends, self-glowing adhesive tapes, self-glowing foils, self-glowing glues and sealants, self-glowing ceramic glazes, self-glowing writing and printing inks, self-glowing papers and stickers, self-glowing textiles and cloth, self-glowing glasses, and self-glowing plastic composites. The “self-glowing” refers to the ability to emit visible light or photon, without simultaneously being externally excited, or consumption of energy (like lamps) or materials (like candle) at the same time. These self-glowing blends or composites can glow in the darkness without consuming electricity and can be utilized in the following applications:
    • 1. Self-glowing marking, labeling, decoration, film coating, and paintings on the body of bicycles, automobiles, ships, and aircrafts. Such utility will display the contour, the location, and color of the subject's body at night or in darkness with the benefits of decoration and safety of traveling.
    • 2. Self-glowing marking, labeling, decoration, film coating, and paintings on the walls, the swimming pools, stairs, steps, and other outstanding objects inside or outside of a building. Beside apparent decoration utility in the darkness, they can also show the contour or locations of the objects in the darkness to avoid injury related liability.
    • 3. Low-level lighting source, i.e. “Electric less” lamps. By applying the blend on artificial lamp surfaces, they can self-glow in the darkness for hours after lamp is turned off. When lamp is back on, they can be optically excited and charged up, while shifting the lamp color to longer wavelength and warmer appearance.
    • 4. The blends can be utilized in many other special self-glowing products to save electricity and pollution and prevent safety hazards in darkness. For example, self-glowing paper and ink will allow people to write in the darkness without need for lamps. Self-glowing paint, tapes, ceramic glaze, and labels will allow people to act in the darkness without the need for electric lamps. Self-glowing glass and plastic articles will decorate or display at night without need for electric lamps. Besides conserving electricity and environment, self-glowing products may be used to direct traffic and prevent injury associated with power outage or electric lamps failure. These products also provide convenient safety measures in products such as self-glowing textiles that pedestrian and bicyclists can wear at night, without the need for electric lamps.
