How it works- 

Copper is an amazing heat conductor. Sand can be heated to 500 degrees before it melts and is perfect for holding heat. As the candle heats the copper it heats the whole bucket which creates a radiant heater. The Crisco candle burns for days and can last up to a week before swapping out. The stone base is used to keep your floor form getting warm.

Step 1- Build your candle. 

Melt the shortening and pour into a mason jar with the candle wick. Let dry. This will create a long burn candle that will last up to 7 days.

Step 2- Build your heater base

Cut the copper roll so that it makes a circle touching the sides and bottom of the beer bucket. Make sure the copper is about 2 inches above the top of the bucket.

Step 3- Pour in sand

Step 4- Place the candle in the sand about an inch or so from the top of the copper. 

Thats it!
