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.

Methods of creating a batch of recycled glass from mixed color glass cullet. In one embodiment, the method includes receiving at a glass plant a weight and color composition percentage of a first batch of mixed color cullet. The glass plant also receives a weight and color composition percentage of a second batch of mixed color cullet. The weight and color composition percentage of the first batch and the second batch are combined to generate a combined weight and composition percentage. The combined weight and composition are percentage are used to generate, automatically at a glass plant, a formulation to produce glass of a desired color.

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.

In order to provide a method which can produce red glass vessels and which is attended by low cost in respect of the raw materials/starting materials and also in respect of control of process parameters, an appropriate method for producing red glass vessels is proposed in which a colourless molten glass composition containing at most 3% by mass of tin oxide and at most 3% by mass of copper oxide is produced, where the resultant colourless molten glass composition is refined under neutral conditions with sodium sulphate and/or calcium sulphate and with a carbon-containing reducing agent with a molar carbon/sulphate ratio of from 0.5 to 5, where glass vessels are moulded from said refined glass composition, and where the glass vessels are cooled to a temperature of below 520 degrees C. to 580 degrees C.

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.
