* calculated from mass fraction data

(*) Calculations were made to examine some of the PDG/LBL values (in 2024) for E_Glass.
(*) The components of E_Glass are based on the Web page of SDD Materials: E-Glass fiberglass.
(*) TiO₂, Na₂O, K₂O, Fe₂O₃, F₂ in E_Glass were igunored. To compensate this, fractional weights of Al₂O₃, MgO, and B₂O₃ were increased by 1%, 0.5%, and 2.5%, respectively.
