a) at least 7% wt and at most 49% wt of iron, Fe,
b) at most 1.3% wt of copper, Cu,
c) at least 24% wt and at most 44% wt of silicon dioxide, SiO2,
d) at least 1.0% wt and at most 20% wt of calcium oxide, CaO,
e) at least 0.10% wt and at most 1.50% wt of zinc, Zn,
f) at least 0.10% wt and at most 2.5% wt of magnesium oxide, MgO, and
g) at most 0.100% wt of lead, Pb.
