Morphology
flowers + of + zinc
The phrase 'flowers of zinc' uses an archaic/specialized sense of 'flowers' meaning a fine powder (zinc oxide), which is not the everyday meaning 'blossoms' a B1 learner would know. Because the intended sense is lexicalized and domain-specific rather than compositional from 'flowers' + 'of' + 'zinc', its meaning is not predictable from the parts and would likely be misinterpreted, so it is opaque.
Etymology
Flowers of zinc comes from old chemists: when zinc was heated and changed into a soft white powder, the tiny flakes looked like small flowers, so people called it flowers of zinc. That's why the phrase means today the white zinc oxide used as a pigment and in ointments.
