    • A funnel glass containing PbO for a cathode ray tube, wherein when the composition is represented by wt % based on oxides, the content of SrO is at least 1.0 wt %, the content of BaO is at least 1.0 wt %, and the ratio of the content of PbO to the total amount of PbO, SrO, BaO, CaO and MgO, is at most 0.69, and whereby the lead elution A of the glass as measured by the following method A is at most 1.0 &mgr;g/cm2, and the X-ray absorption coefficient at a wavelength of 0.6 Å is at least 40 cm−1: Method A: The glass is immersed in distilled and deionized water at 90° C. for 20 hours, whereupon the glass is taken out, and the amount of lead in the distilled and deionized water is measured by inductively coupled plasma emission spectrometry, and the measured value of the amount of lead is divided by the surface area of the glass, and the product is taken as the lead elution A.
    • 含有用于阴极射线管的PbO的漏斗玻璃,其中,当组合物以氧化物为基准的重量%表示时,SrO的含量为至少1.0重量%,BaO的含量为至少1.0重量% PbO,SrO,BaO,CaO和MgO的总量的PbO含量为0.69以下,由以下方法A测定的玻璃的铅洗脱A为1.0mug / cm 2以下, 波长为0.6的X射线吸收系数为至少40cm -1:方法A:将玻璃在90℃下浸入蒸馏水和去离子水中20小时,取出玻璃, 通过电感耦合等离子体发射光谱法测量蒸馏水和去离子水中的铅,将铅的测量值除以玻璃的表面积,将产物作为铅洗脱液A.
