Ceramic colours containing effect pigments and a liquid glass forming component for decoration of metallic, ceramic and glassy articles and a process for the preparation of a ceramic glaze.

STA-18, a molecular sieve having a SFW structure and containing phosphorus in the framework, is described. STA-18AP (as prepared) can have a lower alkyl amine, such as trimethylamine, and one of 1,6-(1,4-diazabicyclo[2.2.2]octane)hexyl cations (from diDABCO-C6) or 1,7-(1,4-diazabicyclo[2.2.2]octane)heptyl cations (from diDABCO-C7) or 1,8-(1,4-diazabicyclo[2.2.2]octane)octyl cations (from diDABCO-C8) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide, can be used as a pH modifier for making SAPO STA-18. A calcined product, STA-18C, formed from STA-18AP is also described. Methods of preparing STA-18AP, STA-18C and metal containing calcined counterparts of STA-18C are described along with methods of using STA-18C and metal containing calcined counterparts of STA-18C in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.

A universal or all-purpose laser marking composition for forming satisfactorily dark laser marks on a wide variety of substrates is provided. The marking composition comprises an enhancer of nitrides, carbides, silicides, and combinations thereof. The enhancer may be selected one or more of ferromanganese, ferrosilicon, Fe.sub.xSi.sub.(1-x) where X can range from about 0.005 to 0.995, Fe.sub.5Si.sub.2, MgFeSi, SiC, CaSi, (Co)Mo, MoSi.sub.2, TiSi.sub.2, ZrSi.sub.2, WSi.sub.2, MnSi.sub.2, YSi, Cu.sub.5Si, Ni.sub.2Si, Fe.sub.3C, Fe.sub.7C.sub.3 and Fe.sub.2C, MoC, Mo.sub.2C, Mo.sub.3C.sub.2, YC.sub.2, WC, Al.sub.4C.sub.3, Mg.sub.2C, Mg.sub.2C.sub.3, CaC.sub.2, LaC.sub.2, Ta.sub.4C.sub.3, Fe.sub.2N, Fe.sub.3N, Fe.sub.4N, Fe.sub.7N.sub.3, Fe.sub.16N.sub.2, MoN, Mo.sub.2N, W.sub.2N, WN, WN.sub.2, and combinations thereof and combinations thereof. Upon disposing the marking composition on a substrate and exposing the marking composition to laser radiation, the marking composition absorbs the laser radiation, increases in temperature, chemically bonds with the substrate, and when formed on each of a metal, glass, ceramic, stone, and plastic substrates, the mark has a negative L dark contrast value of at least 1 compared to a mark formed by the marking composition without the enhancer.
