 This approach to match making was further refined in the proceeding decades, culminating with the
'Promethean Match' that was patented by Samuel Jones of London in 1828.His match consisted of a small glass capsule containing a chemical composition of sulfuric acid colored with indigo and coated on the exterior with potassium chlorate, all of which was wrapped up in rolls of paper.The immediate ignition of this particular form of a match was achieved by crushing the capsule with a pair of pliers, mixing and releasing the ingredients in order for it to become alight.
