A finite universal algebra \(A\) is called dualisable if the quasivariety generated by \(A\) has a nice duality [cf. \textit{D. M. Clark} and \textit{B. A. Davey}, Natural dualities for the working algebraist, Cambridge: Cambridge Univ. Press (1998; Zbl 0910.08001)]. The main result of the paper is that \(A\) can be embedded into a non-dualisable algebra iff the sum of arities of operations of \(A\) is \(>1\).
