( 1975 ) observed that many glasses having a stoichiometry similar to nepheline
would , if doped with sodium chloride and sodium sulfide , darken when
irradiated with short wavelength ultraviolet ( 2537 Å ) . No deterioration of the ...

As previously indicated , many of the glasses are photochromic prior to the
growth of the hackmanite phase . In the early low - temperature ( ~ 650°C )
stages of heat treatment , carnegeite , nepheline , and sodium fluoride are formed
.

As discussed in Section V , A , only negative birefringence was observed as a
microstructural birefringence of stretched sodium borosilicates in the literature .
This also can be explained in line with the current discussion , although many of
the ...
