Florentine pot
The Florentine pot , also called the Florentine bottle or Florentine vase , works on the principle of the oil separator and in practice is usually part of an apparatus for distilling essential oils .
Essential oils are often highly volatile (that is, they evaporate quickly at higher temperatures). They are therefore often extracted (detached) from the plant material with the help of water vapor . The resulting mixture of essential oil and water vapor is condensed again by cooling and passed into a bottle (said Florentine pot). This process is called steam distillation
In this bottle, the lighter essential oil floats on top of the heavier water . At the lower end of the vessel is the outlet for a U-shaped pipe. As soon as the liquid level in the Florentine pot rises above the height of the pipe, the water begins to flow out of the bottle. If the liquid level in the vessel falls below the outlet opening of the pipe, the outflow of water stops automatically. This means that a lower layer of water always remains in the Florentine pot.
The essential oil is skimmed off through the upper opening as soon as it has reached a sufficient layer thickness in the pot.
