0 a white or colourless mineral used in making aluminium, glass and other substances -- kriolit
Fox worked for the cryolite company between 1864 and 1905.
On the other hand, the synthetic form of cryolite is chargeable under heading 28.29 as aluminium sodium fluoride.
I am told that cryolite in its natural form is exempt from the charge under heading 25.28.
There cryolite is used, which is sodium aluminium fluoride, and this is probably the most potent localised source of giving a neighbourhood risk.
The work also includes very large amounts of fluorides, which are an essential part of the manufacture of cryolite, one of the materials by which alumina is made into aluminium.
A few ocular prostheses today are made of cryolite glass.
There, she guarded the cryolite minewhich provided ore vitally needed for the production of aluminumfrom the 16th to the 26th.
It is mainly produced as a precursor to aluminum trifluoride and synthetic cryolite.
