  • Floral base
    Patent number: 4064301
    Abstract: A floral base is made by hot wire cutting a foam of expanded polystyrene beads, thereby forming a smooth skin over the cells at the cut surface; differentially wire brushing the hot wire cut surface, lightly in some areas so that the wires only slice the surface skin and more deeply in adjacent areas so that the wires gouge out beads to form cavities and roughly parallel channels; then coating the surface with a latex paint. The resultant material surprisingly simulates the appearance of rough weathered lumber.
