The deterioration of carbonaceous rocks in urban areas can be roughly classified in three kinds of feature patterns visibly distinguishable on the rock surface. In this paper the three different kinds of deterioration are described and interpreted in

The description in Pliny’s ‘Natural History’ of gilding bronze by using mercury becomes clearer if it is seen as a process in which mercury is used only as an adhesive for the gold leaf and in which it is not necessary to heat the object after

The skill of the Florentine glass-blowers of the 17th century is well attested by many surviving examples of their craftmanship. Among the less familiar of these are a number of liquid-in-glass thermometers made about 1660 for the Accademia del Cimen

The discolouration and decay of stonework in smokey atmospheres is a worldwide problem and enormous sums are spent on cleaning and restoration. It is surprising, therefore, that little research has been done on the nature of the process of decay, it

There is evidence that oil-fired carbonaceous particles play an important role in the gypsum formation on urban limestone. The course of the stone decay registered in Venice strongly supports this view. A model simulating the impact of atmospheric fa

The e-type effect on the water vapor continuum, suggested by Bignell's laboratory experiments, is investigated in the atmospheric extinction spectrum of the sun between 8 and 13 µm. A classification of atmospheres in terms of precipitable water w, s

The transformation of airborne SO2 into SO4— taking place in a polluted urban atmosphere has been investigated in terms of the equilibrium of the system composed of SO2, liquid water and NH3. The procedure used for selecting, compiling and assembli

Oil-fired carbonaceous particles are consistently found inside gypsum-calcite layers covering some marbles located in northern Italy urban areas. A series of analyses performed on the particles and on thin sections of sulfated layers show that these

Salinity and tide heights recorded for a month at P 0 , a point in the northern section of the Venetian lagoon, are the basic experimental data used to construct a numerical model which describes the salinity variations at P 0 as a function of the ti

Measurements of the monochromatic atmospheric extinction of solar radiation (in the 0.65–13.5 µm wavelength interval) in the Po Valley and neighboring mountainous areas show the occurrence during the morning (after the night inversion) of an evolu
