Yes, air bubbles are quite usual in Ikora glass.
>> Here is my blue vase shown in the 1928 catalogue as well, with lots of bubbles of all sizes...
If you message me your e-mail adress (click the small envelope to the left), I can send you a picture of the catalogue page in the Ikora book, showing your bowl.
That other Art Deco vase is a far more complex piece, so I wouldn't expect every blue Ikora piece to glow under UV.
