  • Method of placing markings on a polymer plastic grave marker
    Patent number: 6203643
    Abstract: A method of placing markings on a polymer plastic grave marker. Firstly, providing a polymer plastic grave marker of a known polymer composition. The polymer plastic grave marker is of a first color. Secondly, removing material from a surface of the polymer plastic grave marker to form hollow markings. Thirdly, providing liquid polymer that is capable of bonding with the known polymer composition, in one or more other colors. Fourthly, filling the hollow markings in the polymer plastic grave marker with the liquid polymer. The liquid polymer bonds with the known polymer composition, thereby providing integral colored markings. The polymers used are chosen to have the same coefficient of thermal expansion and moisture absorption and are preferably the same polymer.
