An oil bottle, also known as a CRUSE or CRUET, is a container used to store and dispense oil. It typically has a narrow neck and a wide base, and is made of glass or ceramic. The word 'CRUSE' is derived from the Latin word for 'JAR, ' while 'CRUET' is derived from the French word for 'small jug.' Oil bottles are commonly used in religious ceremonies, such as the Jewish ritual of pouring oil over bread. They are also used in cooking, to add flavor to dishes.
