Saint Thomas is now on the easel to receive a grisaille underpainting in oils. After being crushed by my attempt to make an egg-tempera grisaille underpainting on this panel of Thomas and Jesus, et al., I have decided to move my historical experimentations to a panel of more manageable dimensions. Moses in the Rock is the only picture I have made using egg tempera as an underpainting and it is quite small. This represents the largest panel I have ever undertaken with the most fully developed charters as well. Egg tempera is very slow (and I already work very slowly), and having already allowed a 5 year window to make this picture, I shall try to fully embrace those other challenges in a noble fashion in addition to honoring my time.
Mixing the medium for the thinning of colors for underpainting.
Applying a coat of thinned shellac over the absorbent gesso and egg tempera.
