The preparation of the superconductor Hg‐1223 (see this month's title picture) with 60‐70% phase purity by a simplified route is reported. The material is produced in a single step from air‐stable mono‐oxides and exhibits a sharp superconducting transition, possibly due to the lack of observable defects (see Fig.).
