The correspondences: Mercury
Volac is ranked as a President, and the Presidents of Goetia come from Samael. Samael is the shell of Sephira Hod. In my magick with the Presidents of Goetia, I use the correspondences of Hod even for the Qlipha Samael:
Ruling planet: Mercury
Astrological hour: Mercury
Paper seal colour: orange
The best day for magick with Volac is Wednesday. If you want to fine tune your magick, then do the ritual during the astrological hour of Mercury.
