coppernitrateArtificial patination is mostly based on empirical recipes for which the result is difficult to forecast. Little is known about the final corrosion compound formed on the patinated object. Therefore, different patinas based on copper nitrate—an ingredient recurrent in numerous references...
Our chemicals allow you to create stunning, authentic-looking patinas on metals, including copper, brass, bronze, nickel, stainless steel, aluminum & more.
While metals like brass and copper are beautiful on their own, artists and craftsmen who work with them sometimes like to "color" the metals. Most often, what they mean by this is adding a patina to the metal. A patina is a colored film that sits on the surface, produced through the ...
) patinas on copper, brass, and bronze because copper salts are blue-green, but zinc salts are not. You canprobablywipe on a copper-based patina solution with enough effort if that's the look you seek ... but only practice makes perfect....
The results show that some parts of the objects are covered by different kinds of black voluntary patina, indicating the occurrence of various patination recipes and different substrate alloys for the so-called family of "black bronzes". Another kind of chemical patina has been detected on a ...
indicating the occurrence of various patination recipes and differentrnsubstrate alloys for the so-called family of "black bronzes".rnAnother kind of chemical patina has been detected on a Roman object; it is red-colouredrnand has not been described to our knowledge in the literatu...
Different recipes for patina were reviewed, choosing one for its historical coherence and proven efficacy and using it for the patination of both a pure copper sheet and a Cu alloy containing 1 % Au, in order to compare the different features of the pure metal and the all...
Patinas obtained on artistic cast bronze and pure copper plates by using 19th century Western traditional patination techniques and recipes were studied. SEM-EDXS and ATR/FT-IR analysis were performed in order to investigate patinas chemical nature and structure. Further information on their ...
Chemical and physical characterization of artificial patinas obtained on artistic bronzes and coppers by using the 19th century Western traditional patination techniques and recipes by means of SEM–EDS, light microscopy and ATR/FT-IR has been done in previous studies [I.Z. Balta, L. Robbiola,...
An experimentation program was developed to reproduce black patina, based on the use of Japanese recipes. We tried to differentiate the effect of the alloying element (Au, Ag, As, Sn) and the effects of the chemical treatment. These patinas were studied by means of several analytical methods...
