Cosmetic pencils having cores consisting of water-set mixtures of plaster of paris, mica or other laminar material and pigment or color are disclosed. The mixtures are between 30 wgt % and 75 wgt % plaster of paris. The pencils may be made either by pouring water-based slurries of the mixtures into hollow pencil cases, or by introducing pre-formed cores into two-part cases which are subsequently secured together. The pencils can be easily sharpened and may contain a wide range of additives such as preservatives and bacterioistats.
