Barcelona, Planeta, 1989; 178-198. the ban was not enforced or put into effect In particular, it appears that upon the photoinduced oxidation of its sulfidic counterion, the Cd(2+) ions reprecipitated at the paint/varnish interface after having formed a complex with oxalate ions that themselves are considered to be degradation products of the resin and/or oil in the varnish.

However, the alternatives do have the advantage of being less expensive and less toxic. Specifications. “Cadmium pigments are light fast which generally means they won’t fade for 100 years or longer,” explains Rizvi. The cadmium-free pigment was developed after three years of research and development. This painting differs from the Ensor case in the fact that (a) a varnish was superimposed onto the degraded paint surface and (b) the CdS paint area is entirely covered with an opaque crust. In this way, the results presented in this paper demonstrate how, through a judicious combined use of several microanalytical methods with speciation capabilities, many new insights can be obtained from two minute, but highly complex and heterogeneous paint samples. Artificially aged model samples. The cadmium yellow (cadmium sulphide, CdS) used by Van Gogh was a relatively new pigment, of which it has recently been discovered that in unvarnished paintings, it oxidises with air (to cadmium sulphate; CdSO 4) making the pigments lose colour and luminosity. 2011 Feb 15;83(4):1214-23. doi: 10.1021/ac102424h.
