Murano ? Charger

Large - 13.75" diameter - cased glass charger with clear rim. Slightly inverted dome shape. Large clear polished pontil bottom. Any ideas on the maker?

Am I seeing things? If you look at the last photo where I rather unsuccessfully tried to get a photo of the pontil, there appears to be a blue "something", possibly a signature, that looks a bit like Cenedese, though their mark is usually acid etched. But I can't find it again! Maybe it's reflection through the glass of the cobalt?

All help appreciated!

 

There seems to be something bluish near the bottom right corner of that last pic. I'm not sure if it is anything nevermind a sig. I tried editing that bluish whatever with not much luck. Following are a few of my edits.

Thank you, Ladybranch for going to all the trouble! The mark showed up in my photo, and although I've gone over the back of the plate again and again, I can't seem to find it. It's probably nothing, but it's driving me crazy.

 

nice plate !!!

 

To me, the "signature" looks like the outline of a gondola in ladybranch's enhancements.

 

It looks like it could be a viking longboat ? Gorgeous thing!

 

Gee, that does look like a gondola! I couldn't find such a sig. actually on glass. The J.I. Co. (Jordan's Import Co.) foil label is of a gondola. As this is an import company rather than the maker, this couldn't be by them.

Wait a moment... according to one of the replies on the following query Jordan did have a furnace in Murano making things of their own (repky #5) an had partnerships with Toso &Barbini and probably Cenedese (reply #6).
"...partnered with Toso and Barbini which she said is documented, and probably Cenedese because that's probably who made the fish..."

Thank you all for the great information and discussion! Sorry it's taken me a day to express that. I'm in SC, not far from the coast (and have a son and his family who are right on the coast), and have been pre-occupied with Hurricane Matthew. Wishing Florida and the Carolinas a safe weekend!

 

& you too !!!!
