The present invention provides a glass sheet having soda-lime-silica glass composition with a high visible light transmittance (L.sub.tC) of at least 89% with a dominant wavelength (DW) from about 490 to 505 nanometers and purity (Pe) of no more than 1% for control thickness of 5.66 mm and methods of making the same. The glass composition comprising a low iron raw material, a total iron oxide (Fe.sub.2O.sub.3) of 0.02 to 0.06 wt. %, ferrous (FeO) from 0.006 to 0.02 wt. %, redox (FeO/Fe.sub.2O.sub.3) from about 0.30 to 0.55, Cr.sub.2O.sub.3 from about 0.3 to 10 ppm, TiO.sub.2 from about 50 to 500 ppm, SnO.sub.2 from about 10 to 500 ppm, and a critical amount from about 0.10 to 0.25 wt. % of SO.sub.3. The low content of iron oxide is achieved by the partial substitution of regular raw materials by low iron raw materials, with a complete substitution of regular dolomite by a low iron dolomite with a maximum content of 0.020 wt. % Fe.sub.2O.sub.3.

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.

An apparatus for and method of color-striking a color-strikable article. The method includes 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.
