SWEDISH ART GLASS
This green vase is approximately 200mm tall. The stem of the vase is the same colour as the base and has a slight flare being approximately 22mm in diameter. The bubbles appear to go horizontally around the ball, and are slightly larger than most, although the bubbles are graduated, getting smaller as they go up. The base of the ball has been 'ground' flat.
The label is an oval shape and has a black background with metalic silver lettering. This is the label of "G Hardy Co." who were an importer of glass into Britain in the 50's & 60's. They imported glass items from Sweden and Murano in Italy. As yet, I do not know definitely which company in Sweden made this vase, my guess would be Kosta due to the size and arrangement of the bubbles. Hardy's label for Italian glass is the same but says "Venetian Art Glass".

Below is a diferent type of vase where the stem has a 'rolled over' rim, often referred to as Jack in the Pulpit (JIP) or 'dog bone' vases. This amber stemmed vase is approximately 285mm (11 inches) tall (to the highest point of the rim). The base is 'ground' flat and polished. The bubbles are large and elongated and well controlled around the base. These vases were made in Sweden by Aseda Glasbruk. They come in a variety of colours, and can be seen with bases the same colour as the stem, and some have a white inner. The label has the "G Hardy Co." logo, is an oval shape and has a metalic gold background with black lettering, stating "SWEDISH ART GLASS".

Below are some other examples of this type. The red vase is approximately 195mm (7 & 3/4 ")tall

The dark green vase on the left is approximately 248mm (9 & 3/4") tall. The base is an unusual shape a bit like a flying saucer. The stem is clear and has a medium flare and is approximately 25mm (1") across the top. The dark green coloured core of this vase is off centre so the pattern of small bubbles has been distorted. The bottom of the base has a flat and polished finish. (see images below). The label is almost round but with a flattened top. It is very faded but looks as though it has a blue background with silver writing which states" SWEDISH ART GLASS", it also has the G Hardy & co.logo.

The smaller green vase next to it is approximately 203mm (8") tall. The stem is clear with a medium flare and is approximately 24mm (15/16ths of an inch) across. It has small well controlled bubbles in the base which come up in a spiral. The bottom of the base has a flat and polished finish.

The vase third from the left has a black amethyst core and is approximately 248mm (9 & 3/4") tall. The stem is clear and has a medium flare and is approximately 25mm (1") across the top. It has small well controlled bubbles in the base which come up in a spiral. The bottom of the base has a flat and polished finish.

The blue vase on the right is approximately 155mm (6 & 1/8th of an inch) tall. The stem is clear and has a medium flare and is approximately 20mm (3/4") across the top. It has small well controlled bubbles in the base which come up in a spiral, although it does have some elongated bubbles at the bottom of the base. The bottom of the base has a flat and polished finish.
I have seen another pair of green ones with labels which simply stated 'MADE IN SWEDEN'.
