[3] used unsaturated polyester resin (UPR) as binder and alumina and tenorite (copper oxide) as conductive particles in nanosize.
The patterns for the decomposition products were indexed with ICDD files for Ti[O.sub.2] anatase phase and CuO tenorite phase.
on effect of vinegar in bronze vessels) or copper acetate, copper vitriol or copper sulphate and a mixture of black (copper (II) oxide or tenorite) and red (copper (I) oxide or cuprite) copper oxides that forms in the burning of copper (see Hawthorne & Smith 1979, 121 f.).
It was found that in copper containing mixture cinnabar acted as a reducing agent which transformed tenorite (CuO) to Cuprite (Cu2O) however by the addition of sulphur to mixture tenorite was not reduced to cuprite and copper sulfide was formed at temperatures between 300-500oC and transformed to CuSO4 and (CuO.
From the SEM image of CuO nanoparticles it can be seen that the particles shape with different temperature are various, while the morphology of the tenorite nanoparticles in the previous work were of rod shape [15].

Native copper and tenorite (copper oxide) were noted in gossans 'beneath the soil' above some of the virgin copper veins in the 18th/19th century (Lentin 1800).
The standards selected for Cu were azurite ([Cu.sub.3][(C[O.sub.3]).sub.2][(OH).sub.2]), calcosiderite (Cu,[Fe.sub.6][(P[O.sub.4]).sub.4][(OH).sub.8].4([H.sub.2]O O)), cuprite ([Cu.sub.2]O), libethenite ([Cu.sub.2](P[O.sub.4])(OH)), malachite ([Cu.sub.2](C[O.sub.3])[(OH).sub.2]), nissonite ([Cu.sub.2][Mg.sub.2][(P[O.sub.4]).sub.2][(OH).sub.2].5([H.sub.2]O)), pseudomalachite ([Cu.sub.5][(P[O.sub.4]).sub.2][(OH).sub.4]), tenorite (CuO), and CuS[O.sub.4].
In the same small zone in the Cumbres lugar of the Ojuela mine which produced the claringbullite, a few specimens of tenorite pseudomoiphs after paramelaconite were found as microcrystals, as well as brochantite.
The vehicle is available in Carneol Red, Obsidian Black, Calcite White, Tenorite Grey, Iridium Silver and Cubanite Silver colours.
Some surfaces show brick-red cuprite patinas, while others show dull black patinas of tenorite; the color and luster of the uncoated native metal is fairly bright, but the two other tints add variety and aesthetic interest to these fine copper specimens.
