Re: Natural coal material??
once it is charcoal it is all pretty much carbon, charcoal is wood that is heated with low to no oxygen so all the volatiles in it off gas and leave the carbon, there are still come but once you light them fully they turn into "coke" which is pure burning carbon. coconut is a bit denser so they last a bit longer.
i use CH coals and have great results with them, they smell some when lighting but thats the only real down side to them, and price wise to coconaras they are a good amount cheaper
