Is all blue glass cobalt?

1 Answer
Is all blue glass cobalt?
No, not all blue glass is cobalt glass. Only those made with cobalt oxide can be called cobalt. In some pieces, the presence of copper oxide accounts for the color, however, cobalt glass is much more common. You'll find a collection of cobalt glass on 1stDibs.
