I feel that I have to share this lard lamp project with you. It is such a great idea… sort of one stone two birds. There are a lot of waste fat we get from cooking sausage, bacon, duck, pork, and many other greasy foods.
Pouring these greasy oils down the drain pipes not only is a waste, but also could easily clog your sewer line. With this approach, you could recycle the fat, and make a lovely lamp. Check it out.
