  cal’ dewetting of non-volatile liquids. Labyrinthine structures and polygonal networks result from 
  
  spinodal dewetting and heterogeneous nucleation and growth, respectively. They are ‘decorated’ 
  
  with the solute and therefore conserve the transient dewetting pattern as a dried-in structure when 
  
  all the solvent has evaporated [28, 34]. The picture is, however, not complete. The solute may
