Hi, I recently purchased the Vase/Drinking Vessel and hope someone will be able to identify it. My first thoughts were that it could be Sklo Union and now not sure. I have tried various sites but I have not been able to find one like this. Can anyone tell me what this is and who made it. I appreciate your help in anticipation. Height 11.8cm, Base dia. 5.8cm. Concave pontil 4.3cm. The barrel section looks as if it has been put together in two sections and then joined to the base. There are clear signs of air pockets within the glass but this is minimal. There is also a slight lip around the outer rim area. With the base area there is a large thumb nail mark.
