For your safety, I recommend you set this up this in a room with good ventilation, keep the windows open, with good moving airflow.
Place your alcohol-based tincture into a mason jar that will comfortably fit in the mini-crockpot. Place the jar on the bottom of the crock pot.
Carefully pour water around the jar and into the crockpot, creating a water bath. You do not need to use all of the water. Use enough to cover the contents in the jar, but not overflow.
Turn the mini-crock pot on warm and allow the water bath to heat up. Be sure you do not have a lid on the jar, as this will slow or prevent the evaporation process.
The time it takes to evaporate the alcohol will depend on the starting volume, or how much tincture you have.
If you are working with non-cannabis herbs, you can evaporate 10-90% of the alcohol in your tincture. How much you evaporate will determine how strong your end product is. The more alcohol that evaporates away, the more concentrated the tincture becomes.
If you are working with cannabis, the goal to make FECO is to reduce 95-100% of the alcohol. How long this takes will depend on the volume. For example, 1 cup of tincture will take approximately 4-5 hours to evaporate into FECO. More volume will mean more time, and less volume will mean less time.
The alcohol will evaporate during the heating process, reducing the volume and leaving behind a thick, black, sticky substance. This black oil is your medicine, or FECO.
If this black oil gets too sticky or hard to work with, add a few drops of alcohol or carrier oil to the jar and mix well to create a more viscous oil.
Store your FECO in a glass syringe, capsule, or another airtight glass container. Store in a cool, dark place like a medicine cabinet.
Notes
Warning: High-proof alcohol is highly flammable and should not be exposed to open flames. Exposing alcohol to open flames may start a fire or cause an explosion. When evaporating alcohol, take similar precautions when handling gasoline or other flammable liquids and avoid open flames.Need everything? Feeling stuck in the process?
