Abstract
A critical study has been made on the extraction of elemental copper
with silver salt in a silicate glass and a new method for its estimation
in copper-ruby silicate glass is described. The method consists of extraction
of elemental copper with saturated silver sulphate solution
in 0.04 N sulphuric acid and its subsequent estimation by Atomic
Absorption Spectrophotometry. The results showed that only about
5-6% of total copper was present as elemental copper in both types of
copper glasses melted with or without tin. Opposite trends in the extraction
values have been observed in the two types of heat-treated
glasses (with or without tin), which was presumably due to the structural
rearrangement during heat-treatment.
