Title: Vallerysthal/Portieux "Dauphins" or Westmoreland "Argonaut" ?
Post by: Anne E.B. on December 18, 2015, 03:09:56 PM
I've acquired a very nice unmarked white milk glass lidded bowl which is shown in the VP catalogue "Dauphins" no.3814 dated 1894.  However, I see that Westmoreland Glass Co. made what looks to me to be an identical version referred to as "Argonaut".  From what I can gather Westmoreland marked the inside lid with a WG, but that other companies copied this Westmoreland design and therefore wouldn't have any markings.

So, a couple of questions.  Firstly, how can you tell if it is a genuine Vallerysthal/Portieux piece?  Did Westmoreland acquire VP moulds or just copied the original VP version, or is it a Westmoreland copy?
Hope that all makes sense :-\ ::)

That is a very difficult question without handling both. What I think is that VP used a whiter shade of pale (sorry it was irresistible) which goes clear at the edges where the glass gets thinner, while WG uses a rather garish solid milk glass.

Thanks Ivo.  I've had a close look (having first skipped the light fandango whilst turning cartwheels 'cross the floor ;D)  Its not a solid garish white - I know what you mean.
The extraneous bits of glass which haven't been removed are clear and the thinner parts of the dolphin tails (including outside edges) are actually opalescent with a fiery glow when held to a strong light. 
I'm inclined to believe it is more likely to be VP.
I'm also that much nearer geographically to place of origin, although I know that shouldn't make too much of a difference :)

VP it is - it beats WG hands down 😊

Might ask the Facebook Westmoreland group the molds questions as I know they produced several PV type pieces. Greg Jennings runs the group which is fairly large. They will answer anything in the lines of questions about Westmoreland.

So far I've been informed that Westmoreland did not own/have any PV molds however they copied the designs & made their own molds calling the productions "Faithful Reproductions of Classic Designs".

Any idea of the period in which these reproductions were made just out of interest?

Westmoreland closed in 1984 & the items in question were produced on & off in various colors/treatments for over 40 years.
