Just to clarify where I read my information:
The Art of French Glass |Janine Bloch-Dermant page 15
'While Emile Galle took particular account of the Apperts' metallic oxide combinations, both he and Eugene Rousseau benefited from advice offered by the brothers. In their time the glassware exhibited by the Apperts was held to be in no way inferior to the most beautiful Venetian products(plate 2)'. It is clear in the book btw that Rousseau bought his glass from Appert Freres as well.
A few points about the vases and my link above
-The vases pictured in my link above are from the Legras catalogue 1899. I guess that doesn't mean they were definitely made at Legras especially given Mike's thread you linked to.
- It has been quoted that at least one of them, the 1177 are in a museum collection listed as Appert Freres. I wonder if this is a case of mistaken identity on the museums part?
- Your vases have the same kind of ribbing to the 1177 but are different on the foot and have a three way crimped rim and are a different colourway. I suppose the theories on this could be they are:
a) a Legras piece but a variation on the range?
b) a piece made in the 'spirit' of Legras by someone else? Or conversely made by Legras in the 'spirit' of something else they'd seen.
c) Yours and the 1177 may be pieces made by the same factory, but not necessarily made by Legras, and that they supplied some to Legras(the ones in the Legras catalogues) and others they sold for themselves (perhaps examples like yours), that maybe had slight changes to the design and perhaps weren't finished in the same rigorous way as the finish I would have thought would be on the \Legras pieces (I'm assuming this since all the Legras pieces I've seen have had polished pontil marks, but it could of course be the case that they also sold/made pieces with snapped off pontil marks)
