Normally, I'd call this tulip vase a Quintal Vase, except it only has 4 flower tubes (does that make it a Quaddle?). The only one I have ever seen with 4 tubes! Prattware with underglaze floral decoration in the typical Pratt colors of dark and light brown and blue. The vase is about 6 ¾" tall and the `splay' at the top is about 7"; the rectangular base measures 3" x 2 ¼". Very fine condition with only a small (1/4") edge chips on one of the end flower tubes, and a ¾" very shallow glaze chip or scrape on one corner of the base. Very minor (much less than normal) edge `fritting' at the top, as is often the case with vases of this period (c. 1780). Tubed flower vases were developed in the early 18th Century by the Dutch as a way to display tulips; English potters copied the form toward the end of the 18th Century. See my other Ruby Lane listings for a similarly decorated Qunital (5-tube) Tulip Vase. Together they make a smashing table or sideboard display.
