Murano/Czech art glass controlled bubble small bowl/dish/ashtray. Vintage/retro 70s salmon pink/peach & lilac blue precise bullicante folded

A pretty and petite art glass dish with very precise controlled bubbles.
Most likely Czech due to the typical colouring, but it may also be from Murano, Italy.

It's a pale blue inner, slightly purple/lilac, with a peachy or salmon pink outer casing and lip.
The bubbles are very precise and are very skillfully executed - the work of an artist.
Not sure exactly who it may be attributed to.

1960s or 1970s, typical glass ashtray shape with two folded in corners (but probably too small to use).
Base shows the small signs of wear you'd expect for the era.
No chips or obvious scratches, any marks are microscopic.
Glows salmon pink under UV light, which I believe denotes a Selenium and Cadmium content.

Just 8x3cm.

A beautiful vintage curiosity, a small statement and masterpiece.
