Abstract

The schlagmetal (Dutch Gold), obtained from an alloy of copper and zinc is a cheap alternative for gold leaf, but its colour changes due to oxidations which appear as a result of incorrect manipulations or of exposure to environmental factors (temperature, humidity). This paper presents the influence of shellac based protection film and of two mixtion binders (water and oil based size) on the schlagmetal applied on a gessoed wooden support. To evaluate the behaviour of the metal sheet in the structures presented in this study, the samples were exposed to artificial ageing, and the occurred changes were analyzed by optical microscopy (OM), SEM-EDX and colorimetry in CIE L*a*b* system.

Keywords: Schlagmetal, Gilding size, Artificial aging, OM, SEM-EDX, Colorimetry CIE L*a*b*
