## Letting the glass jar stand for 2–3 days. For substances that will oxidize, just let it stand for just an hour to get rid of most of the sediment, then soak the semi-clear solution with a syringe and use a syringe filter to get rid of the final sediment. | ## Letting the glass jar stand for 2–3 days.

# Put the clear phase in a glass baking dish and let evaporate. Use several glass baking dishes to get more surface for quicker evaporation. Heat, such as a heating mat, often evaporates a portion of the substance. | # Put the clear phase in a glass baking dish and let evaporate.
