1 kg of NH4 FHF was added to glass batch I and 3 kg of NH4 FHF per 100 kg of glass were added to glass batches II, III and IV.
The influence of these additives on the transmission for ultraviolet light is given in the table below for a wavelength of 2804 A with a glass thickness of 1 mm, for example.
