>>351165The name is just shortened from Creosote Sweeping Log. S'posed to help your chimney, but I can't attest to that use. What it's made of is wax and sawdust. The lighter makes flame but you need a constant flame to get a fire going, especially at the beginning.
These logs are perfect for that. You just take little chunks that you carve off with a knife and put them in a ziploc.
