Zusammenfassung:A water resistant and thermally insulating silicate article is produced using a starting mixture having the oxidic composition: from 62 to 68% SiO2; from 1.5 to 5% Al2O3; from 5 to 10% B2O3; from 0.1 to 0.5% CaO+MgO and from 21 to 26% by weight Na2O, all percentages being expressed on a weight basis, and subjecting the mixture to baking at a temperature of 600 to 700 DEG C. The oxidic composition is suitably provided by a mixture of liquid and solid sodium silicate, borax and perlite.
