So ready to do something with these spent coffee grinds we've been saving...

I am a "coffee grounds saver" from way back. They are one of the best things for making compost for the Vegetable Garden. It can take up to a year before they will be ready for the garden and they are too acidic for certain plants, so be careful with that. I've been wanting to try making some "Coffee Bricks" to burn in the fire pit and possibly some small egg crate firestarters for the charcoal smoker and to use in the campfire on the camping trips. I do have some experience making candles years ago, but this will be my first attempt at making the "Coffee Fire Bricks". As with any indoor craft project that involves flamable liquids and materials, it is very important to practice Fire Safety Precautions at all times. Melted Wax is highly combustible and can burst into a raging Grease Fire with little to no warning. Never use water to try and extinguish a grease fire, by the way. That will just cause it to spread out spattering and sizzling like crazy. Dump a large amount of baking soda on it to smother the flames or use one of those food service dry powder extinguishers. No open flames anywhere near it. With that being said, it would be safest to melt the wax in a Water Bath Double Boiler over an electric range. Never try to melt wax in a container placed directly on the heat source unless you want to see what a flash fire looks like. Very bad sign if the wax starts smoking; just sayin'. The melted wax is extremely difficult, if not impossible, to clean out of the melting pot / pitcher, so best to use a cheap aluminum one specifically for that purpose. This cheap aluminum pitcher I recently scored for 6 bucks at WM is ideal for a Wax Candle Pouring pitcher. I'll be melting the wax blocks in the pitcher in a shallow boiling water bath stock pot with a wire rack in the bottom to keep the pitcher from touching the bottom of the stock pot. First thing I need to do is completely dry out the spent coffee grounds by baking them in a cheap cake pan with the oven on it's lowest setting and the oven door slightly cracked open to vent out the moisture. This will take a while, so going to get started on that. Basically, we can use anything that will hold the melted wax for a mold. I'm thinking anything made out of cardboard will work good when wanting to burn the whole thing and also to help with igniting it; cardboard egg cartons, paper towel rolls, milk cartons, etc. I'm also thinking the mini bread and muffin pans lined with coffee filters or parchment paper will also work. THIS IS GOING TO BE SO MUCH FUN!!!
