The article reminds me of a fellow I met on an American Heritage Girls camp out. He melts down his wife’s defunct candles placing the wax in Dixie cups that are half full of chain saw shavings from fire wood cutting. He just covers the saw dust and lets it solidify. Top half of the cup serves as a wick now that I think a little more. It provides the little extra that the fire needs to get going without the danger of accelerants. They are small and light.
