title: [Dimensional changes in die stones with an additive and sodium chloride].
abstract: The obtention of a working model and the preparation of the die must be developed with great care and attention to detail. Based on these principles, a study was conducted referring to the different kinds of special plasters or die plasters available on the market, with respect to dimensional alterations, as well as an investigation of the dimensional behavior of special plasters in the presence of two additives. The results shows that Vel-mix had the greatest difference. All the special plasters brands showed alterations when the Gypsum Hardener were used. These alterations did not occur with sodium chloride.
