title: An explanation for the water distribution in a hygroscopic expansion technique.
abstract: The water distribution in a controlled water addition technique was investigated using a Liquid Scintillation Counter. The mix water arrangement varied in different sections of the investment mass. The water distribution seemed to be the result of the influence of added water and a sprue base.
