Abstract
A graphite mold has riser openings lined with an insulator extending around the periphery and substantially across the bottom of the openings. The bottom portion of the insulator is formed of facing sand and phenolic resin while the peripheral portion of the insulator is formed of a coarser backing sand and phenolic resin. The insulator is baked by residual heat in the mold and decreases in thickness from the bottom toward the top of the riser opening.
