   We report the influence of composition on electrical, dielectric and optical properties of xTeO(2)-ySb(2)O(3)-zPbCl(2) glass system prepared in silica crucibles in air, where x is an element of < 40, 80 >, y is an element of < 0, 20 >, z is an element of < 10, 50 >. The properties of 70TeO(2)-10Sb(2)O(3)-20PbCl(2) composition, prepared in various crucibles, under various atmospheres, melted and annealed under different temperature regimes, are also reported and discussed. The DC conductivity increases with increasing content of PbCl2 while the conduction activation energy decreases at the same time. On the other hand the DC conductivity slightly decreases with increasing concentration of Sb2O3. Temperature dependences of the DC conductivity follow Arrhenius law characterized by single activation energy. The static permittivity shows surprisingly large dependence on used crucibles. Yellow glasses prepared in alumina crucibles have the highest both DC conductivity and static permittivity
