Description: This photograph depicts a coke sample with a caption that reads, "80% NEMACOLIN (-4 1/2" + 1") 20% POCOHONTAS(SLACK) NEMACOLIN CLEANED BY SAND FLOTATION TESTS 1-A&1-B (HIGH SULFUR)". Coke is created at coke plants by burning coal in order to purify it; then, blast furnaces burn layers of coke and iron ore to produce pig iron, the first step of the steelmaking process. This photograph is from the Youngstown Sheet and Tube Company Audiovisual Archives, so it likely depicts a Youngstown company plant. View on Ohio Memory.
