Title: help to decypher measuring jar.
Post by: Paul S. on November 07, 2010, 07:48:54 PM
I spent some hours looking for a maker called 'BELMAN/DELMAN GLASS' - obviously without result, since it actually says 'BELGIAN' :pb:     Does anyone know the reasoning behind being graduated here but using Belgian glass?  and can anyone decypher the etched symbols etc. on the side.    Without a pontil mark, although a fair amount of wear on the base, and is it possible to take a stab at dating.   Something like 6.25"/158mm tall.     Any ideas gratefully received, and thanks for looking. :)

Weird, probably last 30 years or so. Probably made to order on imported blanks by a lab glass supplier.

Acid marking on base, sandblasted on side and wheel cut gradations, numbering looks very sloppy!

Should be older than 30yrs as, according to the info supplied by Bernard in the post above the G 2 R mark would refer to George V or VI (so anytime between 1910-1952). Also it's graduated in Fluid Oz., modern British laboratory measures are almost always graduated in SI units, though I believe Imperial models are still available to order.

I thought about that and decided that was not the mark as it would not have been sandblasted then. Lab glass can get a lot of use and can show wear quickly.

Chemists marks on the side ??   Just a guess  :huh:

As time passed and looking closely at the other thread... I may be wrong as those are also very shoddily produced although not as bad as this one. It is not impossible for a sandblasted mark to have been used at an earlier date that the 70s/80s, just unlikely. Particularly in a shop that could manage acid etching with a stamp and wheel engraving albeit very poorly. It would hardly surprise me that the Foreign made one in the other thread came from the same laboratory glass supplier. Catalogues I have of lab glass show a much higher standard of marking! Moncrieff's hardly touched sand-blasting for marks on lab ware going straight from acid to screen printing.
