1950s cigar ashtray scandinavian or czech - Murano Clamshell

Hi guys anyone know who might have mad this cigar ashtray, thoughts are skrdlovice or Jiri harcuba.  Could be one of the Scandinavian factories just not sure.

Thanks

I'd always understood these "Clam" vases were Murano.

It's not a vase it can stand on its side, this style was made by other glass makers as ashtrays, you cannot hold enough water less than an inch x

They were made by several Murano glassworks, but this is most likely by Cenedese, c.1980s-90s.

It is probably more a decorative dish than a functional piece of glass. An ashtray would need a more secure way of keeping the lit end of the cigar/ette from contacting with the glass when resting it.

ok, done some more digging this is a clamshell ashtray/vase 19580/60s by Fratelli Tosa, it has the double faceted sides. Although this one does not have clear channels for cigarettes. A yellow example is on the bigashtray.com website. Weight and size match as well.

The one claimed to be Fratelli Toso on that website is also very likely Cenedese.

Nic mural glass is a veritable mine field! Think I will concede to just enjoy it and not worry who made it! I agree it could well be by cenedese, shows you cannot go on what people say on the Internet as gospel! That's why I come to you guys when I am not sure great minds and all that xx

I have one signed Oball Murano so probably impossible to pin down to a specific glass house
This one has 2 polished flats on the so can be displayed either straight up or on it's side.

All of the Oball ones I've seen have been in transparent cased glass - Cenedese tended to execute them with opalescence and opaque opal casing.

Of course, there will likely be examples from both factories (and others) doing exactly the opposite.
