Abstract
In this contribution the observational characteristics of F to G type post-
AGB stars, showing both O-rich and C-rich circumstellar chemistry, are revi
ewed. It turns out that binarity and the presence of a stable circumbinary
dusty disc are fundamental properties of these objects. The possible common
origin of the mixed chemistry observed in these systems and in IR-bright [
WC] stars is discussed.
