摘要：
Objects of the present invention are: a lead-free enamel composition comprising finely divided glass particles, finely divided pigment particles and an organic binder, characterised in that the glass of said particles is a lead-free mineral glass, essentially having the composition below, which is expressed in percentages by weight of oxides: SiO245-60 B2O3 0-10 Al2O3 6-17 Na2O0-7 K2O0-7 Li2O0-7 CaO 0-12 BaO13-27 ZnO 3-17 MgO0-9 TiO20-2 ZrO20-7 with Na2O + K2O + Li2O>4 the enamel able to be obtained by firing of said composition; glass-ceramic articles, which are decorated with said enamel; and new lead-free mineral glasses.
