A '''Florence flask'''/'''boiling flask''' is a type of flask used as an item of laboratory glassware and is named after the city Florence.<ref>{{Cite web|url=https://www.merriam-webster.com/dictionary/Florence+flask|title=Definition of FLORENCE FLASK|website=Merriam-webster.com|access-date=14 December 2021}}</ref> It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance. Traditional Florence flasks typically do not have a ground glass joint on their rather longer necks, but typically have a slight lip or flange around the tip of the neck. The common volume for a Florence flask is 1 litre.<ref>{{cite book|last=Thompson|first=Robert|title=Illustrated guide to home chemistry experiments: all lab, no lecture|year=2008|publisher=O'Reilly Media, Inc |page=17 |isbn=978-0-596-51492-1 |location= Sebastopol, Calif. |url=https://books.google.com/books?id=DuJLYq4IkL0C&q=florence+flask&pg=PA17}}</ref>
