Good day,
I have been cataloging artifacts from a trash deposit of a
well-to-do rural site in northern NJ (c1770-1840). Among the glass
artifacts are many fragments of lamp chimneys. There are also some
pieces of table glass and decanters. While shining a UV light on the
table and decanter fragments to check for lead crystal, I noticed that
some of the lamp chimneys also fluoresced icy-blue. I am finding that
about 50% of the lamp glass in the deposit fluoresces. I have seldom
paid much attention to lamp glass and I have never before tried a UV
light on it. Has anyone else noticed or recorded lead crystal lamp
chimneys?
