Welz cadmium yellow iridescent frit vase

I'm such a fan of Welz frit glass, so when this little charmer turned up on eBay UK I had to get it!
It is made from opaque yellow glass, with an iridescent frit decor on a rounded, four sided form with the iconic Welz "daisy".
The vase measures 9.5 cm tall, 4.5 cm across the top rim, & 4.4 cm across the base. The yellow contains cadmium & glows orange under UV light.
Last photo shows it with two other Welz "siblings" that share characteristics which are mixed together in the new vase.
The yellow is a touch paler than the others.
Made by Welz.
