Before treatment, the samples were exposed to outdoor weathering for different periods of time and then treated with a 5 % solution of pure iron (II) sulphate and commercial iron (II) sulphate. It was determined that the pre-weathering time affected the final colour change, as the samples ...
Colour - Energy Bands: The valence electrons, which in other substances produce bonding between individual atoms or small groups of atoms, are shared equally by all the atoms in a piece of a metal. These delocalized electrons are thus able to move over t

W. Weylfurther suggested, on the modern view, that the deepening in colour might be due to the influence of the PbO bond in the glassy structure. On the other hand, it is also well known that colouring oxides such as iron, copper, etc., all produce more intense colours in heavy lead...
