Global Chalks are primarily composed of limestone, made up of tiny fossilized marine organisms called coccoliths. This calcium-rich composition gives chalk its distinctive soft, powdery texture and a clean, slightly alkaline mineral flavor that many find both refreshing and grounding. The natural chalk dust and the familiar shape of chalk pencils often spark childhood curiosity—reminding us of school days, drawing on blackboards, and the simple tactile pleasure of chalky textures. This nostalgic connection, combined with chalk’s unique earthy taste, makes it a fascinating and approachable form of edible earth around the world. Whether smooth and mild or faintly gritty, chalk carries the ancient story of oceans long gone and invites a sensory experience grounded in natural history.
