An intriguing discovery in the field of multiple stellar populations in globular clusters is that some of them show internal variations in the bulk of the heavy-element content. I summarize the chemical properties of one of these clusters, M22, in comparison with the most extreme ω Centauri, underlying the analogies and differences between the two objects.
