Coal
chemical formula: C
( large chunks )
Pure, natural high grade Anthracite Coal, over 95% pure Carbon. Great samples for experimentation and analysis of Coal burning byproducts (Sulfur Dioxide, Nitrogen Oxides, etc). Used in some ancient chemical formulations. Easily ground into a fine powder. The perfect stocking stuffer for those bad little children around Christmas time.
( total weight of the large chunks, approx. 1/2 Lb. ).
