I purchased an altoids tin the other day in which i poked a small hole in the top of. So I already have some 100% cotton cloth patches in which I loaded the altoids tin with.. anyhow I put it in my fireplace and watched when it stopped smoking.. I pulled it out to inspect. When I opened the lid, my charcloth started turning red.. like it had caught a spark. What causes this? Also.. What did I do wrong? I'm hoping someone else has had this issue.. otherwise I'm calling Coast to Coast.. :grin:
