1. Large (12 quart?) cheap stockpot purchased from a dollar store.
2. A kitchen skimmer. I think ours was originally intended for removing food from a stir fryer. Anything that will let you skim off old candle wicks, bugs, etc., will work.
3. A tall plastic cup.
Note: these tools are permanently dedicated to this project.
1. Candle stubs. My wife loves to burn candles. When they have been burned to the point that she can no longer use them, she throws what's left of them into my stockpot which I keep in the garage when not in use.
2. Saw dust. Several years ago I walked into the wood shop of one of my local lumber yards and asked if I could have a plastic grocery bag of sawdust. They were happy to indulge me. After making over 500 firestarters, I am still using the original bag of sawdust.
3. Dixie cups. Dixie makes these in 3 oz. and 5 oz. sizes. Either will work. I prefer 3 oz., since they cost less and work just as well. However, what you see in the photos that follow are 5 oz. cups (purchased by mistake).
4. Aluminum foil (preferably the wide size).
Step 1: Arrange Cups
Arrange the Dixie Cups on the aluminum foil in beehive honeycomb fashion (to minimize gaps between cups, which will reduce spills).
Step 2: Pour Sawdust
Step 3: Melt Candle Stubs in Stockpot
Note: you will find Instructables that instruct always to melt using a double-boiler. That is certainly safer, as the wax can never be hotter than 212 deg. F. if you use this method. I am comfortable using a tall-sided stockpot, using low heat, being patient and never leaving it untended .And I keep a fire extinguisher about 10 feet away just in case.
Step 4: Pour Wax
Pour just enough wax to almost cover the sawdust. Because sawdust will float on molten wax, it's sometimes hard to judge how much to add.
Step 5: Add More Sawdust As Needed
Step 6: Cool and Store
TO LIGHT: make a tear in the side of the cup above the wax/sawdust. Light the exposed edge.
After the stockpot is completely cooled and the wax hardened, I put the leftover sawdust, plastic cup and skimmer in the stockpot and store in the garage until I need them again.
