A process to synthesize silica mesoporous capsules is reported (see Figure), where mineralization takes place at the oil–water interface of reverse emulsion droplets. The capsules exhibit an homothetic morphology. Simple scaling analysis reveals that mineralization takes place above a well‐defined hydrolyzed precursor concentration within the droplets.
