<p>A method for producing a glass-ceramic article, which comprises crystallizing a glass article consisting essentially of from 40 to 60% by weight of SiO2, from 13 to 19% by weight of Al2O3, from 0 to 6% by weight of B2O3, from 8 to 16% by weight of MgO, from 2 to 6% by weight of CaO, from 3 to 9% by weight of ZnO, from 5 to 12% by weight of TiO2, from 0 to 3% by weight of Li2O + Na2O + K2O, from 0 to 3% by weight of P2O5 and from 0 to 2% by weight of ZrO2.</p> |
