Other early match-like devices were based on the property of various combustible substances mixed with potassium chlorate to ignite when moistened with strong acid. More important was the property of chlorates to form mixtures with combustibles of low ignition point which were ignited by friction (John Walker, 1827). However, such matches containing essentially potassium chlorate, antimony sulfide, and later sulfur (lucifers), mbbed within a fold of glass powder-coated paper, were hard to initiate and unreHable.

Many of the methacrylate polymers used at the beginning of these Investigations were prepared by Stuart Raynolds. Richard A. Tauson carried out the Initial studies on the effect of temperature. The authors wish particularly to thank Dr. John Walker, Director Emeritus of the National Gallery of Art, for his great personal interest, support, and encouragement In this research. The work of the Center Is principally made possible through the generosity of the Andrew W. Mellon Foundation.
