These results represent the first step for applying an appropriate conservation strategy for bronze sculptures with similar characteristics. In terms of corrosion, it is characterised by the presence of oxides. The alloy matches that of other sculptures cast in that period. The data revealed a ternary alloy of Cu, Sn and Zn, with Pb, Fe, As, Bi and Mn as minor elements. For this purpose, a multi-analytical approach consisting of X-ray fluorescence (XRF), X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM-EDS) was carried out to characterise the bulk metal and corrosion layers. Background Ive had this Maine buoy bell wind chime for about eight years now. This study obtained data on the sculpture's elemental composition and corrosion products, gathering important historical and technical information. This instructable will show you a fast, safe method, using common household chemicals that you probably already have, to produce a rich rust patina on iron and steel to give it a weathered, aged appearance.

It may be the air forming oxides or another chemical added to bond molecularly with the surface. Patinas are generally achieved by causing the metal present to react with another element. The outdoor sculpture of the first Portuguese king, D. Patina Formulas The surface of metals may be colored, a patina added either chemically or with heat.
