摘要：
The lacquer contains a white pigment with a grain size bigger than all other pigments in the lacquer. This white pigment either changes its color itself under the influence of heat, or under the influence of heat with a substance coacting with the pigment. Preferably used is a natural or synthetic hard polymer, or in particular, calcium carbonate with an admixture of approximately 10% sodium glycolate.
