    • A water-based black enamel composition capable of being deposited on a glass substrate, especially on a glass sheet. The enamel composition includes: 20 to 40% by weight of water-soluble sodium silicate and/or potassium silicate; a water-soluble base, in an amount sufficient for the pH of the composition to be at least 10.5; 5 to 25% by weight of water; 40 to 60% by weight of a metal oxide chosen from the group consisting of copper oxides, iron oxides, cobalt oxides, mixtures of these oxides, and mixtures of at least one of the oxides with chromium oxide(s); less than 10% by weight of zinc oxide; at least 10% by weight of a glass frit having a melting point below 680° C.; and less than 10% by weight of a glass frit having a Littleton point above 700° C. A glazing, especially an automobile glazing, including at least one glass sheet can have at least one of the faces of the glass sheet coated at least partially with the enamel composition.
    • 一种能够沉积在玻璃基板上,特别是玻璃板上的水性黑色搪瓷组合物。 搪瓷组合物包括:20〜40重量%的水溶性硅酸钠和/或硅酸钾; 足以使组合物的pH为至少10.5的水溶性碱; 5至25重量%的水; 40至60重量%的选自氧化铜,氧化铁,钴氧化物,这些氧化物的混合物以及至少一种氧化物与氧化铬的混合物的金属氧化物; 小于10重量%的氧化锌; 至少10重量%的熔点低于680℃的玻璃料; 并且具有小于10重量%的Littleton点高于700℃的玻璃料。包括至少一个玻璃板的玻璃窗,特别是汽车玻璃板可以具有至少部分地涂覆有玻璃板的至少一个表面 与搪瓷组合物。
