This Unique Stone, made from superior quality beneficiated mineral gypsum, has been formulated to produce exceptional stability and very accurate reproduction of details. Specially designed for basing crown and bridge model construction, an easy flow property has been incorporated in this material. The optimum balance of fluidity and thixotropy permits it to be poured in to base formers without vibration to produce a bubble free cast. The remarkable improvement in the flow properties permits entry of slurry to the finest nooks and crevices, resulting in a superior reproduction. This also has a better surface hardness in comparison to regular base stone, while the usual low expansion characteristics are retained.
