A Florence flask (also known as a boiling flask) is a type of flask used as an item of laboratory glassware. It can be used as a container to hold solutions of chemicals. A Florence flask has a round body with a single long neck and with either a round or a flat bottom. A Florence flask with a flat bottom may stand upright alone on a flat surface; flasks with round bottoms need support to stand upright. It is designed for uniform heating 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 coated with alkaliFact|date=February 2007 to prevent cracks or defacing of the glass. The flask is named after Florence, Italy. "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. A common size for a Florence flask is a volume of 1 liter.
