Zirconium oxide is used in the production of ceramic colors or stains for ceramic tile and sanitary wares. Zirconia and siHca are fired together to form zircon in the presence of small amounts of other elements which are trapped in the zircon lattice to form colors such as tin—vanadium yellow, praseodymium—zircon yellow [68187-15-5] vanadium—zircon blue [12067-91 -3] iron—zircon pink [68412-79-3] indium—vanadium orange (105—108).

Soap scum tends to be built up as fine layers of calcium or magnesium fatty acids on the bathroom surfaces, gradually dulling the surface and serving as a matrix for trapping other soils, such as sloughed skin cells, dirt, lint, and mildew. Many bathroom surfaces are fabricated to be shiny, and the soap scum, which is white or cream colored, tends to become apparent when the shine is dulled. As the more popular bathroom colors are pale or white, it is hard to see the soap scum itself on the surface, owing to the lack of color contrast. Soap scum is much more apparent on dark surfaces (like black ceramic tiles) or on transparent surfaces (like transparent shower doors). It is therefore somewhat hard for the consumer to determine that the soap scum has been completely removed from the surface except by the reappearance of the native shine of the surfaces. 

Another route to stable high-reflectance standards is the use of ceramic tiles or white glass materials. Such materials are usually used only in the visible region of the spectrum due to absorbances shown by the pigments in the UV and NIR. Typically, the tiles are a ceramic baked onto a metallic substrate, with the white pigment usually being titanium dioxide. Such standard materials are provided by Erie Ceramics and the OMH. These standards are used heavily in the color measurement instrumentation in which durability is the key factor in their selection. A similar standard, under the appellation of SRM-2019, has been provided by NIST for use in the... 

More robust standards than paper are generally used in the standardization of spectrophotometers and spectrocolorimeters. These include ceramic tiles, such as those from the British Ceramic Research Association (BCRA), that are available in both calibrated and uncalibrated form from the NPL and other associated laboratories. Similar tiles are available from Erie Ceramics but must be sent to an outside agency for calibration. These tile sets provide both highly saturated and pastel colors, along with a number of nonneutral grays. The BCRA sets also provide a metameric pair to allow the user another method of checking instrument accuracy. 

Any product that depends on aesthetics for consideration for purchase and use will be improved by the use of color. Hence, many ceramic products, such as tile, sanitary ware, porcelain enameled appHances, tableware, and some stmctural clay products and glasses, contain colorants. 

Uses. The most important areas of use of pigments are paints, varnishes, plastics, artists colors, printing inks for paper and textiles, leather decoration, building materials (cement, renderings, concrete bricks and tiles—mostly based on iron oxide and chromium oxide pigments), leather imitates, floor coverings, rubber, paper, cosmetics, ceramic glazes, and enamels. 

Glazes are usually tested on small samples of bisque-fired clay called test tiles or c/ay slabs (see Activity 4.3, p. 173). It is advisable to test glaze colors first to determine if they are suitable before using them on ceramic pieces.
