摘要:
The invention relates to the glass industry. It concerns glasses of low lead content characterized in being prepared from glass forming batches consisting essentially, in weight percent on the oxide basis of:______________________________________ SiO.sub.2 66-70 BaO 5-9.5 B.sub.2 O.sub.3 0-3 PbO 1.5-5 Al.sub.2 O.sub.3 2-4.5 MgO + CaO 0-3.5 Li.sub.2 O 0.5-1.6 As.sub.2 O.sub.3 + Sb.sub.2 O.sub.3 0-1 Na.sub.2 O 7-9.5 BaO + MgO + CaO 8-11 K.sub.2 O 5-8.5 Li.sub.2 O + Na.sub.2 O + K.sub.2 O 14.5-17 Na.sub.2 O:K.sub.2 O
