<p>The invention relates to an open pore mold based on inorganic, partially open pore light granulate based on at least one material from the group of alkali silicates, alkali-alkali earth silicates, aluminosilicates, borosilicates, and variants in the three-material system CaO-SiO2- A12O3 in combination with additional metal oxides such as TiO2 FeO3 Mn2O3. It has a bulk density of 0.10 to 0.60 kg/dm3 measured according to DIN EN 1097-3, wherein the light granulate has a hydrophobized surface applied thereto, and an organic binding agent is bonded to the mold.</p> |
