Fill up a 4 oz or larger mason jar 3/4 of the way with calendula flowers.
Add 2 oz of sweet almond oil and 2 oz of apricot oil to the jar, making sure to cover the calendula flowers and place a lid on the jar.
Using a crock pot or slow cooker, that has a rack insert, place the mason jar on the rack and let warm for 4 to 6 hours on warm or low heat. Remove jar from slow cooker once infused time is up.
Strain the infused oil into a clean container using a mesh strainer or a cheesecloth.
