Three Czech Tango era spatter glass vases in various shapes

Here are three examples of Czech spatter glass of the Tango era, in various forms.
The mostly red spatter vase has a hexagonal form, & measures 15 cm tall, 5.5 cm across the base. It is clear on the inside, with a mix of red, orange, yellow, blue & white spatter.
The rose bowl type vase is an off white, or ivory colour, with a rainbow mixture of spatter in red, orange, maroon, mauve, light blue & mint green.
It measures 12.5 cm tall, 8.5 cm across the base & 7 cm across the top rim.
Please note that the brass flower frog is not the original one, it is slightly too big, but these frogs are very hard to find!
The multicoloured spatter vase has a deep cobalt blue interior, which provides a dark, intense ground for the rainbow of colours on the outside. This spatter has quite a tactile quality. It measures 16.5 cm tall, 5.5 cm across the base. The interesting thing about this vase is that it is the only piece of Tango glass with a marking that I have ever found. It has a moulded mark on the base that says CZECHOSLOVAKIA. An op shop (thrift store) find.
