Title: Lead crystal glass density
Post by: tropdevin on March 04, 2008, 03:05:43 PM

Can anyone help with my query or point me in the right direction please?

I am trying to find values for the density of the clear lead crystal glass used by some of the important Birmingham / Stourbridge manufacturers in the mid 1850s.  This is all to do with which maker may have made a group of paperweights whose density is around 2.88 to 2.93 (which only just qualifies as lead crystal glass).  Density values won't solve the problem, but it may help show the right direction.

I know the density range for paperweights from:
  Bacchus 2.96 to 3.10
  Arculus 3.08 to 3.12  (early 1900s)
  Richardson 3.10 to 3.17 (1840s and 1900s)
  Walsh Walsh 3.16 to 3.21 (early - mid 1900s)

I would like to find out if possible what the figures are for glass from makers such as Davis, Greathead & Green; Webb; Stevens & Williams; Rice Harris; and others!  I know that someone was measuring uranium glass densities a few years ago, but I am not sure who it was.
