Disclosed are a miserite crystallized glass for an artificial tooth and a method for coloring same, the method enabling a production of a uniform shade without degrading the physical properties of a crystallized glass by means of simply adding a small amount of coloring additive powder when preparing the crystallized glass. A miserite crystallized glass for an artificial tooth according to the present invention is colored with any one of the shades in groups A, B, C and D of the Vita shade guide which is a tooth shade reference. The miserite crystallized glass has a miserite crystal phase as the main phase and comprises a hydroxyapatite crystal phase and a xonotlite crystal phase as additional phases.

The subject matter described herein includes a method of manufacturing colored borosilicate glass including, preparing a raw material composition to form a homogenous powdered mixture, placing the homogenous powdered mixture in a container, heating the mixture to a temperature of 2500-3000 F., charging the container with additional homogenous powdered mixture until the container is full, melting the homogenous powdered mixture until it forms molten borosilicate glass, and refining the molten borosilicate glass between 2800-3200 F. to allow air to escape and the glass to fully homogenize.

A method of color-striking a color-strikable article including the steps of: conveying a color-strikable article within a proximity of an energizer, and selectively color-striking said article with said energizer to produce a predetermined pattern on the article.

Latent colorant material compositions, soda-lime-silica glass compositions, and related methods of manufacturing color-strikable glass containers. The latent colorant material compositions may be introduced into a plurality of base glass compositions having redox numbers in the range of ?40 to +20 to produce color-strikable glass compositions and color-strikable glass containers. The latent colorant material compositions introduced into the base glass compositions include a mixture of cuprous oxide (Cu.sub.2O), stannous oxide (SnO), bismuth oxide (Bi.sub.2O.sub.3), and carbon (C). After formation, the color-strikable glass containers may be heat-treated to strike red or black therein.

The invention provides a method for producing composite nanoparticles, the method using a first compound capable of transitioning from a monoclinic to a tetragonal rutile crystal state upon heating, and having the steps of subjecting the first compound to a hydrothermal synthesis to create anisotropic crystals of the compound; encapsulating the first compound with a second compound to create a core-shell construct; and annealing the construct as needed. Also provided is a device for continuously synthesizing composite nanoparticles, the device having a first precursor supply and a second precursor supply; a mixer to homogeneously combine the first precursor and second precursor to create a liquor; a first microreactor to subject the liquor to hydrothermic conditions to create an\isotropic particles in a continuous operation mode; and a second microreactor for coating the particles with a third precursor to create a core-shell construct.
