Gilding: Mediums, Mordants & Techniques

This is an ongoing project as I learn gilding techniques and better comprehend their application. As part of my own experimentation I have used supports that I am likely to use in a real application, 230gm pergamenata and 100lb Strathmore Bristol Vellum. My intent is to also make a similar test page on parchment when I get the chance. I am testing both modern and period mordants and paints.

There are sources detailing how to make period mordants for gilding, most common of which is Cennini’s Il Libro dell' Arte. My intent is to experiment with the various recipes so that I can make my own batches from scratch, however, since I wanted instant gratification I have so far been using mordants purchased from others.

Making & Storing Glair

Various dictionary definitions describe it as "a sizing liquid made from egg white". It can be used as both a binder for paint pigment and, much to my surprise, as a size for laying down gold leaf.1
