VII. Special glass

Mario Moretti


There is no end to glass with different compositions, used for particular applications like alumina-silicate glass (fibreglass, objects to be submitted to chemical tempering), phosphate glass (glass with no silica where the glazing is phosphoric anhydride, used for bio-glass and fertilizer glass), glass with no oxygen like calcogenuri (arsenides, sulphurs) which are used in opto-electronics and halides (fluorides...) used for special optical-fibres for infrared transmissions, etc..
