and the debunking of such is available from Fausta.
My personal favorite, though not the most influentional one, is:
Item #15, glass: He also introduced crystal glasses (which had been invented after experiments with rock crystal by Abbas ibn Firnas may be correct if the glasses they have in mind were carved from rock crystal (quartz).
However, the Romans manufactured and used glass during the Republican period, and glassware became popular during Augustus’s reign (Augustus lived in 31 B.C. – 14 A.D.). A later example (circa AD 150/160-200) of pre-Islam drinking glasses was found in Sweden at the Öremölla burial site.
There are other rare surviving drinking vessels made of glass that predate Islam.
I have read several discussions of glass much earlier than this in history books.
Just as a for instance:
A craft is born
The earliest man-made glass objects, mainly non-transparent glass beads, are thought to date back to around 3500 BC, with finds in Egypt and Eastern Mesopotamia. In the third millennium, in central Mesopotamia, the basic raw materials of glass were being used principally to produce glazes on pots and vases. The discovery may have been coincidental, with calciferous sand finding its way into an overheated kiln and combining with soda to form a coloured glaze on the ceramics. It was then, above all, Phoenician merchants and sailors who spread this new art along the coasts of the Mediterranean.
The oldest fragments of glass vases (evidence of the origins of the hollow glass industry), however, date back to the 16th century BC and were found in Mesopotamia. Hollow glass production was also evolving around this time in Egypt, and there is evidence of other ancient glassmaking activities emerging independently in Mycenae (Greece), China and North Tyrol.
This comes from A Brief History of Glass Online and I happen to know more than usual about the 16th century BC glass in Mesopotamia because of my book.
