Catalytic Scent Lampe Fuel

I'm addicted to my catalytic scent lamp, and have several brands of lamps, including the famous berger brand lampe. The fuel is expensive to buy, and I deceided to make my own. I use this instead of store bought fuel, but I'll admit it doesn't burn as cleanly.

• Ready In: 5 mins
• Yields: 12 oz

Ingredients

• 12  ounces  rubbing alcohol (90% isopropyl-alcohol)
• 1⁄2 teaspoon  scented  oil (essential oil)

Directions

1. IMPORTANT: You must use a 90% strength isopropyl, or rubbing, alcohol. The 70% isopropyl alcohol contains too much water in the solution, and will not burn. You can find the 90% strength at drugstores on the same shelf next to the 70% solution.
2. ALSO: Use the best undiluted quality oil as you can -- to check for purity, place one drop on a sheet of clean paper. The drop should completey evaporate if the essential oil is pure. If it leaves a greasy, oily spot, select another oil.
3. CONVERSION NOTE: I measure my essential oils in ML, not OZ or other units. 1/2 teaspoon equals approximately 2ML.
4. Open a 12oz bottle of 90% isopropyl alcohol.
5. Add the essential oil.
6. Screw the cap back on. Shake to mix, and you're done!
