flint
Quick Summary
Flint is a hard, impure variety of quartz, typically gray to black, known for producing sparks when struck with steel. This property made it crucial for tools and weapons during the Stone Age. Flint is a type of chert, a fine-grained silica mineral. Its uniform grain and brittleness allowed early humans to shape sharp tools by flaking. Today, crushed flint serves as an abrasive in sandpapers and in industries that grind raw materials for ceramics and paints, as it avoids iron contamination.12

miningHistory…the first mineral used was flint, which, because of its conchoidal fracturing pattern, could be broken into sharp-edged pieces that were useful as scrapers, knives, and arrowheads. During the Neolithic Period, or New Stone Age (about 8000–2000 bce), shafts up to 100 metres (330 feet) deep were sunk in soft…

wheel lock…that pressed a shard of flint or a piece of iron pyrite against an iron wheel with a milled edge; the wheel was rotated and sparks flew. The principle was used in the design of the flint-and-wheel cigarette lighter.

…(1720) Staffordshire potter to use flint for improving the quality of earthenware mixture by making it whiter. Figures now attributed to him reveal variously toned clays, as well as colours clouded to enrich them. He quite possibly originated the popular pew groups; i.e., two or more rigidly posed, salt-glazed stoneware…
