I have been filling out my list of things I believe will be useful when the economic collapse happens. I have been looking at several types of survival candles and wondered if anyone had any experience with Colgans, Nuwick, and others. I also see candles in a can with several wicks and don't quite understand how the multiple or replaceable wicks work. I also don't understand the advantages or bee's wax or tallow. Any guidance will be greatly appreciated, thanks.
