A large cylindrical vacuum chamber has been constructed (1180 mm long, 405 mm diameter) and used for impregnating unconsolidated, undisturbed sediment samples. To ensure complete sample impregnation and to avoid stress fracturing of the resin, a very slow-curing impregnating mixture of Daystar Escon CR6-1 polyester resin with 0.5% by volume cumene hydroperoxide hardener is used in this chamber. This gives a curing time for large samples of about 1-3 months. With such long curing times, all but the finest-grained samples have been successfully impregnated.
