This is a French art glass stick vase, pate de verre. The maker is Andre Delatte. The date is circa 1912.
Delatte produced quite a few of these tall stick vases in different colors. Most of the vases were acid stamped on the lower belly, where the vase might be held, and so the signature gets worn away. This vase has only tiny remnants of the signature, and not enough to show in a photograph.
The stick vases were of different heights and different widths in the neck, and of course different colors. What is common among all of the Delatte stick vases is that the lower belly is indented slightly in three places, so that the belly is bulbous versus round. The colors are fused into clear glass, speckled on the belly, and streaking on the long skinny necks. Pate de verre is the French term for a firing method on the glass where crushed glass of different colors is added to a mixture, creating the final colors and patterns.
This specific vase is 16 ¼” high, 1 ¼” wide at the mouth, and 5” wide at the belly. The primary color is pinkish with mostly blue and a few streaks of yellow. The overall color effect appears purplish in some lights and pinkish in other lights, so basically purple or pink.
The rim is flat. There are some tiny clear spots near the rim where the added ground colored glass didn’t quite reach, and these spots are smooth. The pontil is indented and smooth.
There are no nicks, chips or cracks.
