Murano Mandruzzato multi-faceted art glass bowl/dish/ashtray. Vintage retro 60s/70s. Silver label, red cased sommerso. Mid century MCM round

A fantastic Murano art glass dish/bowl with original silver paper label. Made in Italy, most likely by Mandruzzato.
It's a decahedron from above (10 sided shape), with pentagon shaped cut faceted sides (layers of 10, then 10, then 8 five-sided shapes), tapering down to a octagonal base.
Complex!!!

There's 28 cut sides following a half sphere shape, which reflect the light in an amazing way.
It's ruby red with a round semi-circular well internally, and a slight layer of red floating colour (sommerso). The outer cased glass is clear.
Flat polished rim and base.
Label reads 'Murano Glass, made in Italy'.

I'm guessing it's 1960s or 1970s as it's typical of the era and the label shows signs of age.
Hand made, mouth blown by an artist - quite a feat!
