Matchbox striking strips contain crushed glass powder for friction

Abrasive glass grit on box strips creates the friction heat needed to ignite match heads

The dark brown striking strip on safety match boxes is coated with a mixture of red phosphorus, binder, and finely ground glass powder. The microscopic glass grit creates intense frictional resistance when the match head is drawn across it, generating localised heat to trigger chemical ignition.
