Grounds / Priming
When I was in college in the 1980's I did course on materials and were taught a recipe to make a primer called a half oil ground. It followed the same recipe as a tradirional gesso ground; rabbit skin glue, calcium carbonate, titanium white only we added half the volume with boiled linseed oil and a egg yolk to help emulsify the mixture.
Is this a safe recipe to use? I remember enjoying painting on it.
Thanks Steven Lewis

A half glue/oil ground has the same issues
associated with the use of animal glue (hygroscopic, very reactive to changes
in relative humidity, etc). Other than this, a properly emulsified half glue/oil ground
is reasonably permanent. These grounds are more flexible than straight
chalk-glue and true gesso grounds. They are more brittle than oil and acrylic
dispersion grounds and are best reserved for rigid supports.
