I have identified numerous restoration in-painting materials on
Greek vases, including early water-soluble paints, presumably gum,
or animal glue binders (solubility)), shellac-based (solubility and
UV fluorescence); wax-based (solubility); oil-based (solubility).  I
have also seen gutta percha, casein and cellulose nitrate used as
adhesives, but I have never identified them as paint media.

Later applications of paint were generally soluble in acetone, and
were probably acrylic or PVA emulsion-based paints, commensurate
with the same adhesives used.

If you are interested, I still have numerous samples of the
inpainting on fills, which you are welcome to have for analysis.  I
have not looked at any of the pigments used.
