Materials, archaeological glass

It seems appropriate, therefore, to begin a survey of archaeological materials with a discussion of inorganic materials - from minerals and rocks, the most abundant materials on the planet, to those extracted, derived, or made from them, such as metals and alloys, glass and ceramics (Chapters 1-7). Organic and biological materials produced by, or derived from plants or animals are discussed next (Chapters 8-15). Finally, the atmosphere and the hydrosphere, which make up most of the environment that affects all materials and determines the way they decay, are surveyed (Chapter 17). [Pg.21]

Some solid materials are very intractable to analysis by standard methods and cannot be easily vaporized or dissolved in common solvents. Glass, bone, dried paint, and archaeological samples are common examples. These materials would now be examined by laser ablation, a technique that produces an aerosol of particulate matter. The laser can be used in its defocused mode for surface profiling or in its focused mode for depth profiling. Interestingly, lasers can be used to vaporize even thermally labile materials through use of the matrix-assisted laser desorption ionization (MALDI) method variant. [Pg.280]

NRA has a wide range of applications, including use in investigations of metals, glasses, and semiconductor materials, and in such diverse fields as physics, archaeology, biology, and geology. [Pg.681]
