Abstract
A match which is difficult for young children to ignite utilizes a protective coating on the tip of a match head which prevents ignition of the sulfur and potassium chlorate-containing mixture when an attempt is made to strike the match in the usual manner with its stem substantially perpendicular to the friction surface of the matchbook. The protective coating requires a special manipulation of the match whereby its stem is disposed at an angle preferably less than about forty degrees with respect to the friction surface so that the unprotected side of the match head can rub against the friction and ignite the match.
