The bole is polished with a brush before the gold; the gold is burnished afterwards. In the practice Ferragut describes, the gold is burnished with an agate stone and the bole is wetted with water alone, without glue, when the leaf is laid. If you are not going to burnish, mordant gilding is a different technique: you have the \u003ca href=\"\/en\/products\/mixtion-al-agua-para-dorar-1-l\"\u003ewater-based gilding mordant\u003c\/a\u003e.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eYellow bole or red bole?\u003c\/summary\u003e\u003cdiv class=\"innv-faq__a\"\u003eThe colour of the bole shows through slightly and gives the gold its final tone, and the colours in the range can be mixed together. In the altarpiece practice documented by Ferragut (GE-IIC), yellow is usually applied over the whole surface and red only in the areas to be burnished; the author himself points out that the colour has varied over the periods (red bole over the whole surface on Baroque altarpieces, black bole for silver on early 20th-century frames).
