I am reading “The Illuminated Alphabet” by Timothy Noad and Patricia Seligman which gives a gesso recipe of:
12 parts of slaked plaster (dental grade)
4 parts white lead
1 1/2 parts of fish glue (seccotine)
2 parts of sugar (crystals or coffee sugar)
A pinch of Armenian bole
In my research I have noticed that just like in baking there is no universal recipe for certain common items. So this left me wondering what the other options are.
