Materials and substances – B2–C1

This 17-word B2-C1 deck collects rarer, more specific material terms: minerals and chemicals (sandstone, sulphur, radium, solvent), historical or specialty raw materials (hemp, flax, tortoiseshell, incense), and technical words (buffer, suspension, resin). At this level you'll follow news reports about carbon monoxide poisoning, archaeological or geological descriptions, and recognize words like resin or sap that appear often in natural-science texts. Ideal for reading higher-level articles or academic material in English.
