    What is titanium dioxide-Why is it used in food products

    Titanium dioxide, or TiO2, sometimes referred to as E171, is an inorganic, solid substance used in a wide range of consumer goods including cosmetics, paint, plastic and food, according to the American Chemistry Council. In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a "paint primer" – it often goes on a hard-shelled candy like Skittles before the color is added to give it a "uniform shine."

    Titanium dioxide for Chinese ceramic glaze-Glazing & Restoration

    Several products make up the Coldglaze PRO 2 System. These are combined to create the optimum reglazing or repainting application. As a result, the System is trusted by museums, curators and restoration experts worldwide for use on priceless items and artefacts.Coldglaze Clear Gloss is a two-part, water-resistant, very tough glaze with excellent non-yellowing qualities which cures to a smooth, hard finish. It offers high strength surface adhesion and has been tested for 20 cycles in a dishwasher at 60°C without signs of deterioration.For repainting, Coldglaze Gloss can be mixed with pigments or oil colours and applied via paintbrush or airbrush. Adding Titanium Dioxide White Pigment will colour the gloss white rather than the standard clear finish.When reglazing, Coldglaze is normally applied via airbrush. When airbrushing, PT146 Thinners must be added to the Gloss to thin it suitably. Lowering the viscosity of Coldglaze with Thinners can also help make application via paintbrush easier.

    Titanium dioxide for Chinese ceramic glaze-Titanium Dioxide

    TiO2 occurs in many silicates in nature, accounting for over 1% of the earth's crust. Thus it is manufactured using a variety of materials and processes. Titanium dioxide power is very fine-grained and it agglomerates, so glazes containing it need to be sieved to break down the small lumps (even a high-speed propeller mixer often won't do it).Although titanium is the strongest white pigment known for many uses, in ceramics the whiteness (and opacity) it imparts to glazes is due to its tendency to crystallize during cooling. While titanium dioxide is used in glazes as an opacifier, it is not as effective and easy to use as tin oxide or zircon. It can be used as an additive to enliven (variegate, crystallize) the color and texture of glazes by introducing crystallization. Rutile works in a similar manner, typically both become saturated in the melt beyond about 5-6%, producing a dry and unstable glaze surface. In moderate amounts, it encourages strong melts, durable surfaces and rich visual textures.Titanium is available both as raw and surface-treated products. Non-pigmentary grades flow more freely in the dry state. Self-opacified enamels are made by adding titanium during smelting to supersaturation. Upon firing the enamel, the titanium crystallizes or precipitates to produce the opacity. Titania is also used in dry process enameling on cast iron appliances for its effect on acid resistance, color and texture. In glass, non-pigmentary titanium dioxide increases the refractive index and intensifies color.

    Lithopone: an alternative to titanium dioxide

    Lithopone was developed in the 1870s as a substitute for lead carbonate (lead white), to overcome its drawbacks of toxicity and poor weathering resistance. Within a few years, titanium dioxide displaced lithopone to become the white pigment (PW6) par excellence in the industry and the world’s best-selling inorganic pigment. However, titanium is a product whose price is subject to large price variations due to product availability. These price increases affect the competitiveness of finished products, and so the search for an alternative to titanium dioxide has generated a variety of possibilities to optimise its use.

This extraction is carried on so that the resulting product, after the addition of the required amount of sulphuric acid, is in the form of a dry powdered .mass, in which approximately 95 per cent of the titanium is in a soluble form. Th dry powdered mass is thenextractedin suitable leaching tanks with water, whereby a solution of approximately 70 grams of sulphuric acid and 100 grams of titanium oxide to the liter, is obtained.After settling, the clear solution containing the titanium oxide, is run oil andfurther processed, whereby a roduct is obtained containing approximate y 35 per cent titanium oxide, 2 per cent sulphuric acid and 63 per cent of water.

    Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide ("zinc white"), zinc sulfide, and white lead.
