Ingredients
or, préparation jaune, gomme adragante, colle de poisson
Preparation Steps
The gilding is generally composed of gold grains mixed with a yellow preparation to aid application (p. 818). Binders mentioned in contemporary texts like Ibn Badis and confirmed by the study include gum tragacanth (gomme adragante) and fish glue (colle de poisson) for better adhesion (p. 820). The beautiful brilliant surfaces are the result of careful burnishing (brunissage) (p. 820).

Evidence
"Dans la majorité des cas, la dorure... paraît constituée de grains d'or mêlés à une préparation jaune, probablement pour faciliter l'application. (p. 818)"
Remarks
XRF measurements showed that most gold does not contain silver, except for a few late manuscripts (BNF Arabe 6983, 1184, 6989, 7211) where silver values (around 4% in 7211) might indicate natural gold or a specific mix (p. 818, note 61).
