Abstract
A form and process for casting concrete blocks, each having at least one side textured. The blocks are cast in cavities which have a resilient insert on at least one side for imparting texture to the blocks. After the cast blocks are cured, the form is inverted and placed on a support surface. At least the side having the resilient insert is moved laterally away from the block and the form is lifted to leave the block on the support surface. The textured side can release from the form despite deep grooves and crevices simulating natural stones.
