An olive oil lamp is a surprisingly safe and simple lamp that you can do-it-yourself. It produces light, as much as, or more than, an ordinary candle, and is an alternative to kerosene-style oil lamps. The concept of burning oil from vegetables (olive oil) in the home rather than petroleum based kerosene seems more appealing, less toxic, and safer.
The Romans and other ancients regularly burned olive oil in their lamps, so, the concept is sound. Pure olive oil will not produce smoke, while other types of vegetable oils may produce some residual smoke while burning.
For those who are curious, the cost of burning olive oil in this lamp will depend on wick size (flame size and corresponding oil consumption), while my own experiment consumed 2 ounces (1/8 cup) of olive oil in 5 hours. This calculates out to about 10-cents per hour depending on how cheap you can find pure olive oil. An ordinary Votive candle may cost about 3 to 5-cents per hour to burn, although probably not as bright as the oil lamp.

Step 1: Olive Oil Lamp Parts
You will need an ordinary metal coat hanger, a wick, a canning jar (these are heat treated and can withstand the hot temperature), and needle-nose pliers.
The wick shown in this photo is a typical kerosene lamp wick. Using a scissors, I cut the wick in half (length wise) so it wouldn’t be as fat as what is shown in the photo. You can use an ordinary candle wick.
TIP: A coat hanger is somewhat difficult to work and bend into a coil, while an easier approach is to use #12 gauge bare copper 'ground' wire, available at most hardware and 'big box' stores. It's softer and easier to work with.
Step 2: Bend Hanger Back and Forth Until It Snaps
Grip the pliers firmly to the metal wire of the coat hanger and twist back and forth until the wire snaps.
Step 3: Wrap the Wire Around the Needle-nose Pliers
Using the needle-nose pliers, grip the end of the wire as shown, and then wrap the wire around the pliers about five times. Do this somewhat loosely so as to make it easier to slide the wind off of the pliers afterward.
Step 4: Slide the Coil Off of the Pliers
Use a screwdriver to assist in pushing the wound wire off of the pliers. If you wound too tightly in the previous step, this will be more difficult to remove...
Step 5: Wire Wound Coil to Hold the Wick
The wound wire will serve to hold the wick.
Step 6: Form a Loop to Hold the Wick Coil Flat on the Jar's Bottom
Form and bend the wire while using your pliers to shape it such that the wound portion of the wick holder from the previous step will sit on the bottom of the jar, in the middle of its diameter as shown in the photo (looking down into the jar).
Bend the rest of the wire up the edge of the jar so you can form a handle to support it on the jar's lip edge.
Refer to the final side view image of the olive oil lamp.
Step 7: Bend the Top Portion of the Wick Holder
Bend back the top portion of the wick holder as shown. This will allow the wick to point somewhat upwards when we insert it later.
Step 8: Form a Hook
Form a hook to hang over the edge of the jar as shown. Be sure that the hook is positioned such that the wick coil sits flat on the bottom of the jar.
Step 9: Feed Wick Through Holder
Using the needle-nose pliers, pry apart one of the upper winds of the wick coil so that the wick will slip through as shown.
Step 10: Secure the Wick
Once the wick is through the wire, pinch the wire enough so the wick is ‘just’ secure enough and won’t fall back through. Not too tight though, or you won’t be able to easily feed the wick later – after it burns some somewhat.
Step 11: Trim the Wick
Trim excess wick. Too much wick and the flame will smoke. Too little wick and the flame will be small.
Step 12: Add Pure Olive Oil
Fill the jar with pure olive oil to a level part way up the wick holder. Pour the oil over the top of the wick to speed up the soak.
Step 13: Light the Wick
After the wick is fully absorbed, light the wick. You will notice that olive oil is not nearly as readily flammable as petroleum fuels and will take longer to light. This very fact assures that if the mixture is spilled, the oil itself will not ignite like other oils would.
Step 14: Insert Wick Assembly Back Into Jar
Insert the flaming wick assembly back into the jar so that the extra wick material is sitting and soaking in the olive oil.
Step 15: Remember... It's a Flame
As with any open burning flame, use care and caution. Respect the flame!
