Most wrought alloys are provided in conditions that have been strengthened by various amounts of cold work or heat treatment. Cold worked tempers are the result of cold rolling or drawing by prescribed amounts of plastic deformation from the annealed condition. Alloys that respond to strengthening by heat treatment are referred to as precipitation or age hardenable. Cold worked conditions can also be thermally treated at relatively low temperatures to affect a slight decrease in strength (stress rehef annealed) to benefit other properties, such as corrosion resistance and formabiUty.

From the correlation between the ancient pottery and modern clay one can draw several significant conclusions in addition to the most immediately obvious one that the matching ancient pots were locally made. The amount of temper in the ancient pottery, as evidenced by our comparison with the clay source, has not diluted or otherwise significantly altered the compositional pattern of the ceramic. Also the pottery must not have significantly changed in composition during burial. In addition we observed a small but significant difference between the composition... 

Art s utopia, the counter-factual yet-to-come , is draped in black.45 Darkness marks the place where possibility holds out against actuality. Black works against the deceitful sensuality of culture s facade. Adorno s insistence on black reacted to what seemed a world of ever-louder colours. In 1959 he observed colour s high-pitched shriek in all too much more intense and conspicuous colours . These new colours turned book jackets into advertisements for themselves, in efforts to shake off all that is bookish, old-fashioned and retrogressive about the book.46 Parodic sheen was too able to be misunderstood. Colour may be life s colourful reflections, but it was also a mechanism for drawing attention to the commodity heaven of the post-war. These new commodity colours were synthetic, and the synthetic came to be a testament to the new improved temper of life itself. 

In mid-eighteenth-century France, an eccentric figure of violent chemical opinions and mild temper was drawing the attention of the Parisian intellectual elite. Guillaume-Franfois Rouelle (1703-1770), an inspiring yet extremely absent-minded and easily distracted demonstrator of chemistry at the Jardin du roi, was staging chemical spectacles for a diverse audience of prospective apothecaries, physicians, physicists, philosophes, and literary talents. ...

It is tempting to draw analogy with the development of other analytical technologies (NMR, FAB-MS) and conclude that protein crystallography will soon leave the incubator of "big machine physics" to become an everyday, routine tool used in the medicinal chemistry laboratory. Hopefully, this chapter has shown some of the subtle complexities of sample preparation and handling, data collection, and refinement, etc. that temper this vision and will likely keep this a specialized field for some time.
