Different types of glass are used for various purposes in the essential oil industry. Beakers, graduated cylinders, and volumetric flasks are standard glassware pieces that allow for accurate measurements when diluting or mixing oils. Pipettes and burettes are often used to measure out small amounts of oils for use in blends or recipes. Different expressions of essential oils can be achieved through various processes and technologies. 

One example is supercritical fluid extraction, which uses carbon dioxide as a solvent to extract oil from botanicals. 

This process can produce a higher quality oil with a more concentrated aroma. Another process is called expression, or cold pressing, which presses the peel of certain fruits to release their aromatic oils. Some plant materials, like woodchips or roots, require steam distillation to remove their essential oils. Different essential oils can be used for various purposes. Some essential oils, like lavender oil, can be used for relaxation. Other essential oils, like peppermint oil, can be used for energy or focus. Citrus oils are often used for cleaning because of their fresh scent. 

There are many ways to use essential oils. Oils can be diffused in the air, applied topically to the skin, or added to baths and lotions. Essential oils can also be ingested in some cases, but it is important to use them under the guidance of a doctor before doing so. Essential oils should be stored in dark glass bottles in a cool, dark place. This helps keep the oil quality high and prevents it from going bad too quickly.
