The secret is to use 99% Isopropyl Alcohol (not the same as rubbing alcohol) - available at any Drug Store and inexpensive.
99% Isopropyl Alcohol will get the ceramic top part of the wick to it's right temperature after a minute or two, after which you blow out the flame and the ceramic will remain hot until either snuffed out or the alcohol is used up.
As for adding fragrance, you can either use essential oils (pure natural extracts - usually more expensive) or fragrance oils (synthetic fragrances - usually stronger and much larger fragrance selection and more reasonably priced compared to essential oils.)
How much you use depends on the type of oils you chose to use.
The general rule of thumb I use, is 8 to 10 drops of fragrance or essential oil per 250ml of 99% Isopropyl Alcohol.
Good Luck, have fun and enjoy your Fragrance lamp without breaking the bank.
