Stir it around with a toothpick. Sometimes I will put some coins between the coffee cup warmer and metal dish the oil is in to regulate the heat better.

I have noticed with the transparent oil (made using a quick frozen wash with top shelf, bone dry buds) it can be runnier and more difficult to purge the alcohol. I also noticed that some of the bubbles are actually air bubbles. What I do is turn it off, cover it with a baggie so no dust can get in it and leave it off overnight. Warm it back up the next morning. You may need to let it cool down and warm it back up a couple of times to get all of the air bubbles out.

Certainly, do not over heat it. It will ruin the oil if you do.
