For many years now the drafty old houses of England
have been systematically brought up to date with double glazing
systems thought necessary for the comfort required by today's
society. This has meant the removal of many many precious works
of art , sometimes of considerable antiquity. The quality of
glass used in many of these windows will never be repeated
as processes involving the mixing of metal oxides, sometimes
along with dangerous substances such as arsenic, is no longer
The time is fast approaching where all of these
old houses have been replaced or renovated. This means that
the major source of these valuable antiques will disappear.
Replicas of the design of these old windows
never look as good when made with modern glass. This is
recognized by discerning people who only want original stained
glass made with that beautiful depth of color only obtained
with the old manufacturing methods.
The consequence of coarse will be a considerable
rise in the the value, particularly of the more beautiful windows.
This is all ready happening.
