Chemical Composition, Structure, and Physical Properties

The structure of glass is a consequence of its chemical composition and thus the raw materials used for its production. This chapter is limited to the discussion of glass types relevant to conservation, neglecting specific developments in modern applications. 

Apart from Si02, other inorganic oxides, such as phosphorus oxide, can act as network formers. Alkaline or alkaline earth oxides have a different effect, 

In spite of some general rules for dating glasses by their chemical composition, there are many uncertainties due to the fact that the glass production of each period exhibited a broad variety in composition, although some recipes remained the same over the centuries. Nevertheless, archaeometric studies can

The chemical composition, structure, and physical properties of the Ru films will be the subject of continuing investigations. Of particular interest is the characterization of the potentially mixed-valent [TMPEDTA]RunpzRuHI(H20)5 films and the nature of the conductive [TMPEDTAjRu mirrors.
