Topic: CORDIAL/WINE LAUNAY HAUTIN-1840. FOR SHOW

[neilh]

Is there any way of telling which Baccarat pieces from this era are blown pressure moulded or pressed? Were they all made with the same technique? I am sitting on a Baccarat goblet (with handle), breakfast cup (with handle) and a cup plate - which has an odd gadget mark in the centre of the plate, assuming it's not damage.

  Some details on the air pressure moulded ware can be found at this link under the heading of "characteristics".

  I would add that mold lines seem almost impossible to detect. Of the four pieces  pictured in the link I could only find the faintest of mold line on the cordial. Some cutting done after annealing more often than not.
  I have not handled any of the lacy [stippled] type patterns said to be air pressure moulded. I would think that any example of pressure moulding by air would have a less defined "ghost" impression on the inside corresponding with the major pattern, if not the stippling.

  Pressed articles would be quite smooth on the inside to allow the plunger to exit the mold.

Thanks, on my pieces the mould lines are fairly easy to spot on the top rim but of course disappear into the stippled pattern. From your remarks I think all mine are pressed.

I would contact Siegmar Geiselberger at Pressglas-Korrespondenz and ask his opinion.
He has been incredibly helpful to me regarding the uranium Baccarat becher or tumbler I posted on the very lengthy thread.

He also sent me links in the Pressglas-Korrespondenz with information on the Launay Hautin catalogues and history of the companies.  It makes absolutely fascinating reading.
