A new class of time–temperature indicators based upon aqueous suspensions of triangular silver nanoplates with relatively sharp corners is reported in the Communication by Y. Xia and co‐workers on page 12559 ff. When the nanoplates are subjected to aging in air at various temperatures or under different degrees of acceleration, the sharp corners will be gradually rounded, resulting in a progressive blueshift of the surface plasmon resonance peak accompanied by a series of distinctive colors.
