This is a 4" tall posy vase with a uranium opalescent bowl and a rather plain clear glass foot and stem. The bowl is pale yellow lead crystal and rings beautifully, the foot is, I think, soda glass. I first thought it might be Thomas Webb but now think it is more likely to be James Powell. Hajdamach Plate 256 shows a pale lemon opalescent vase "probably" by Powell and P.266 describes them making this type of glass.
