Complementing carved wood altarpieces and sculptures, the use of metallic leaves became paradigmatic of Portuguese religious ambiences during the 17th and 18th centuries. Although gold has always been favoured, alternative techniques to attain the desired golden lustre were developed simultaneously, mainly with the use of white metallic leaves covered with coloured glazes. Written historic references, present in various technical art texts, indicate that these imitation gildings have been a long time practice. Seldom mentioned, the silvering part of the process is generically described as identical to gilding, while much more attention is given to the golden glazes to be applied over the silvered surface, allowing for their material and technical evolution to be followed. Based on a survey of these historical references, an outline on these developments and the associated terminology is made, keeping in mind that the silver leaf's white glitter also shone on its own right.
