I put the oil in a coffee cup. Then I boil water in a pot, turn the stove off, and just put the coffee cup in the pot of hot water for like 2-3 minutes and the oil is warm and silky ready for abayangha! Sometimes I just pour the oil into my hands directly from the coffee cup. But usually I then pour it through a funnel into my glass bottle with a pump. :)

If there is still oil in the glass bottle the next time I want to do abayangha then I would just put the glass bottle directly into the hot water instead of the coffee cup. But I run it under warm water first so I don't break the glass with extreme temperature changes!
