Abstract
A mold (100) is constructed by forming a shell (125) having a back surface (127) and a mold surface (126) which defines a mold cavity (150), by forming a shell base (124) about the back surface (127) of the shell (125) so as to define an enclosed cavity (134) between the shell base (124) and the shell (125), and by filling the enclosed cavity (134) with substantially incompressible material (135).
