Is this a Sklo Union Vase - Green and clear Knobbled body with a flared top

HI

i used to know who these were attributed to but just can not remember. Just over 12 inches tall with knoble outburst and a flared top, which also has clear glass in it. Around 800g in weight with flat cut rim similiar to a lot of Sklo.

All help appreciated.

Not Sklo Union, they were responsible for pressed glass production.

This is pressed glass, mechanical mold blown. You can see the line in the base photograph

Exactly, mould blown and then probably hot worked to form the 'fingers' at the top. Mould blown is not pressed, when pressed the hot glass is forced into the mould by pressure from a plunger.
