In this instructable, I'll show you the basic recipe for making a Coffee Fire Log. The recipe could still use some tweaking, but it's a good start and a fun and easy project.
Step 1: Gather ingredients
From my searches on the web, there are three ingredients in a FireLog; coffee grounds, wax, and molasses.
I used a bread pan to combine all the ingredients and press the loaf.
I used candles, but you could use the blocks of wax they sell at craft stores (will try during next attempt).
Also, make sure the coffee grounds are completely dry. You can get the grounds free from any Starbucks. If they don't have any sitting out (for compost), then just ask. They are more than happy to get rid of them.
