Beautiful Antique French Blue Opaline Double Saleron, such a delight for your table and collection. The color is a lighter blue, each side is meant to serve either salt or pepper. A knob in the middle makes it easy to pass to other guests at your table.
Rare to find in this color, there are straw-marks on the inside and outside of the wells from where the glass was placed in containers with straw to cool after firing. Wonderful, I rarely find these!
