Abstract
A plugged assembly of cores includes a first core having a first end portion, and a second core having a second end portion. The first end portion of the first core is connected to the second end portion of the second core by a mortise and tenon type connection to form an assembly of the two cores having residual spaces formed by the mortise and tenon type connection, such residual spaces being liable to give rise to flashings when metal is poured over the assembly if not plugged. Residual spaces formed by the mortise and tenon type connection in the assembly of the two cores contain a material configured to reduce the possibility of flashings.
