Play media Method of swirling an Erlenmeyer flask during titration The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in Erlenmeyer flask. Hot vapor condenses on the upper section of the Erlenmeyer flask, reducing solvent loss. Erlenmeyer flasks' narrow necks can also support filter funnels. The last two attributes of Erlenmeyer flasks make them especially appropriate for recrystallization. The sample to be purified is heated to a boil, and sufficient solvent is added for complete dissolution. The receiving flask is filled with a small amount of solvent, and heated to a boil.

The history of glassware dates back to the Phoenicians who fused obsidian together in campfires making the first glassware. Glassware evolved as other ancient civilizations including the Syrians, Egyptians, and Romans refined the art of glassmaking. The art of glassmaking in 16th century Venice was refined to the point intricate shapes could be made. Some time before the turn of the 19th century laboratory glass manufacture from soda lime started in Germany. Most laboratory glassware was manufactured in Germany up until the start of World War I.
