- Small flame, intensified by a stream of directed air, into a long, sharp, single point heat source

- "hundreds or possibly thousands of years"

- Blowpipe powered by breath power or later bellows

- Suggests that the origin of the blow-lamp is from 13oos or 1400s for "renaissance Italy in venice" glassworking

- Difficult to find specific evidence. "Oil lamp + blow pipe + glassworking" can place the tech over thousands of years. Can't just place it all three together and say it was there.

- many objects that COULD have been made by lampworking have other methods of construction using tools that ARE specifically documented.

-"It's possible that at SOME POINT..." etc

- His videos focus more on post-1700s scientific work and laboratory glassmaking

- places the origin in the 1300s based on Corning's statement, but I haven't been able to find those myself so far.
