Chalk is chiefly a suburb but also a civil parish which adjoins the east of Gravesend, Kent, England. As is intuitive, its name comes from the Saxon word cealc meaning a chalkstone.One layer of the chalk carries flints, stones embedded in the chalk, and these were used in building and in providing the means of fire for muskets. The stone is often cut to provide a flat edge as a craft known as flint-knapping. The trade was worked in Chalk from the 17th century onwards.
