The liquid may for example comprise aqeous suspensions of pigmentary titanium dioxide containing traces of iron material. The disc-like member 2 may be formed of aluminium or synthetic plastics which latter may be reinforced for example with glass fibre, brass, aluminium or certain stainless steels. The magnets 11 may be permanent magnets or electro-magnets. The disc may be driven through a friction drive 7, 8 by an electric motor 10. Alternatively the drive may engage with the periphery of the member 2. Radial ribs may be provided on the member 2.
