Sevres footed glass goblet chalice in white opaline signed “sèvres france”

This superb footed goblet is made of white opaline and is signed by the Sèvres factory. This chalice glass features a bowl in milky white and a translucent "soap bubble" foot that takes on orange tones in blue light. Marked "Sèvres - France" at the base, it measures 13.5 X 8 cm in diameter at the rim. I would like to point out a small chip on the inner edge.
