Meaning

Iron filings appear both as material allegedly transformed in metallic operations and as a heating medium differentiated from sand and ash. In the fire catalogue scobs ferri concerns how something heats, not simply what metal it contains. Keeping the local role visible prevents every occurrence of filings from being treated as the same reagent or starting substance.
