beaker

A piece of glassware that comes in various sizes to accomodate various volumes of liquids QUALITATIVELY, as the meniscus on a beaker is way too undefined to be able to read it accurately, so one never uses a beaker to measure accurate volumes. They are made of heat resistant glass and can be used to heat liquids on a hot plate or with a bunsen burner.
