St. Demetrius (270 - October 26, 306AD)

In this particular icon the background gilding is brushed as opposed to being burnished (polished). The effect is a less shiny and less mirroring, satin surface. This type of gilding is also done on red bole and also uses two layers of gold leaf - the only difference is that instead of using an agate burnisher to polish the gold in this case a brush is used to smooth it out.
