Hi---Im new to smoking and acquired a brand new mr meat smoker. I got it at a estate auction and it is from 1989. They don't make it any more but I have smoked some salmon and chicken with it with good results.I have been wondering about using charcoal and read on this forum that charcoal contains wood sawdust and glue. My brother works in a coal mine near Roundup Montana. Would natural coal straight from a mine work for smoking or does it need to be enhanced somehow before using it? Thanks for any help and really like this smoking good site.
