Always weigh your fragrance oil with a scale rather than measuring it with a measuring spoon or cup because different oils can vary in volume.

To measure your fragrance ahead of time you'll want to use a glass container, or what we do in our lab is measure the fragrance just before we're ready to use it and use a wax-lined paper cup. They're disposable so clean up is quick and easy! 

 NOTE: Do NOT measure your fragrances in plastic containers or with plastic measuring cups as fragrances can react with plastic and cause the plastic to break down.
