    Patent number: 4413966
    Abstract: A fluid-release mold is disclosed. The mold includes a preformed, porous mold body having a mold face formed on a first exterior surface and a second surface. A groove is formed in the second surface. A tape covers the groove to form a conduit between the surface of the groove and the surface of the tape facing the groove. The conduit directs pressurized release fluid to the mold. A fluid impermeable backing material is disposed over the second surface of the mold body whereby egress of the fluid from the conduit is prevented except through the mold body in a direction away from the second surface.
