Qualitative Observations

We added extra coal to the fire while I was making my nail, which intensified the heat and flame of the fire. Another thing I noticed about the coal group specifically, was that the fire produced by coal had the lowest and least intense flame out of all the fuel types despite burning quite hot, which made it easy to work with. I failed to create a nail because the shoulder was too skinny when I chopped it off of the iron rod.
