I believe this is a Bohemian art glass triangular vase, most likely by Harrach, and mid-1800s. The hot enamel florals and bugs, butterfly on each side remains vibrant, beautiful and intact. I see only a few of the tiny white enamel raised dots along edges have gone missing over the 170 to 150 years since ti was created, and there are no other flaws to note at all. Full measurements noted on the photos, but it is 8" tall.
Very good to excellent condition throughout, for age and type. There are no flaws at all to report on the thick sandwich glass, a pearly white behind cranberry, and I see no looses to the florals and butterfly hand applied enamel decoration. No chips at base of feet, none at the top rim. The only tiny flaw notable would be a few of the applied raised white dots lining the form have gone missing over time. A fabulous and very appealing triangular form vase, indeed!
