Standard glasses are used to ensure accurate liquidus temperature measurements and furnace temperatures. The supply of the standard glasses used at Pacific Northwest National Laboratory (Standard Reference Material 773 [SRM-773]) has been depleted. Replacement standard glasses for furnace temperature verification and liquidus temperature measurement validation were fabricated and tested. Two glasses-ARG-1 and AmCm2-19-were fabricated in roughly 5 kg batches. The liquidus temperature of the glasses was measured and found to be consistent with those reported in literature.
