As artists and conservator with experience of over 30 years and connoisseur of modern, scientific, analytical procedures / nondestructive and destructive methods /, argues that the scientific team detected only and all layers of the stain, first / protective / paint over the image derived brush and oil paint. More sensationally, known to the general mass of people Madonnas painted on canvas, La Giaconda. Sfumato the painting process in the structure of the entire section painted the back, that is the intersection of the basics of color on canvas, grund, and the payment of the total cross-section images of so-called substantive holder. The whole layer of paint and painted siccative, Renaissance oil on canvas .. Although Leonardo alchemical things and applied research, journalists in ignorance of the methodology are probably insufficiently consulted spokesman scientific reports, or he himself overlooked the conservation ethic and not well versed in painting technology and issues sfumato in terms of pigments and binders / as little as possible /? I think it's hasty inconsistent information is intended for copyright sensationalism without a critical and coherent paragraph a review before putting into the world public? The above problem sfumati whom they mentioned that the coating formed fingers said nothing about the results of analysis of the types of binders and aging, perhaps even in the many layers. If it worked 4 years for all within these layers, there was chemical contamination, Renaissance painting technology and his touch, a kind of unwanted chemical reactions, possibly nano biosphere, which in this case the inevitable happened outside awareness builder current visual status portraits. The color fades and sepia occurs or the protective layer of audit changes? If it is not auditing, it is no small problem, artistic value of the original state of pigment is inevitably lost, irretrievably lost an aging intensity of the original color? Of course, over time, and certainly, as I said, beyond the expected awareness of author L. Davincija. A journalist to proclaim sfumati technology, which is certainly not grounded truth. All of the images next to secondary, primary preserve of aging pigment and binder as whatever it was, the rest are tertiary values. The most common are poor because they are inaccurate alchemical recipes like today, improvisation and voluminous and weight and what I see from the newspaper article and television news is a typical example of under-coordinated information and partly grounded in reported sensational views of conservation rhetoric. Only databases and descriptions of methods potentially hiding the truth and the more recent on this subject, "eternal" theme around this ingenious portrait / the enigmatic smile. It is obvious that science today is increasingly suffering from a lack of journalistic sensationalism, or at least modern criticism, to say the lack of professional ethics, at least the whole of the region of conservation of cultural heritage and fine arts.I've learned not to sfumato painting, but only a method of visual manifestation of deep space. This is not art, it's just kind of applied technology that is not a psychological category of art, certainly not with Leonard because he is basically one of hundreds of individual creators of the world picture, ie, scientist, researcher, designer and technical art for him was what PC Tools to us today.
