The invention relates to a completely new white pigment of the inorganic sort, namely finely divided, preferably micronized, particles from transparent, coloured or uncoloured glass or mixtures of these, especially glass waste of the disposable type. The finely divided particles preferably have a size in the range of 0.01-10 mu m. The white pigment may, in accordance with the invention, be prepared by finely dividing, optionally after coarse crushing, transparent, coloured or uncoloured glass into such small particles that they are usable as white pigment. The invention also relates to a composition of matter comprising the new white pigment particles, especially a composition in the form of a paint. Finally, the invention relates to the use of said glass in finely divided form as white pigment. |
