A wedge apparatus for use with molds and a mold utilizing at least one wedge apparatus. The wedge apparatus includes a pair of attachment portions, each having an attachment surface and a wedge surface, a wedge portion, and a shaft. The wedge portion is slidably attached to the attachment portions and has a center portion terminating in a pair of center edges disposed at opposite angles to the wedge edges such that the center surface and the wedge surfaces form a substantially continuous mold surface. The shaft is attached to the center portion and extends through an opening through a cross member to maintain the center edges of the wedge portion in alignment with the wedge edges of the attachment portions. The wedge apparatus is attached to a plurality of walls to form a portion of a mold, or a complete mold, and may be removed by moving the wedge portion in relation to the attachment portions such that a distance between the attachment portions is altered, separating the wedge apparatus, and the walls of the mold, from the molding material.
