CHOOSING DENTAL PLASTERS FOR USE IN THE CONSERVATION WORKSHOP

W. T. Chase, & Lynda A. Zycherman


ABSTRACT—Six dental plasters were tested and compared to determine their working properties and physical characteristics. The features examined were: viscosity, setting time, exotherm, hardness, smoothness, bubbliness, shrinkage/expansion, ink absorption, ease of engraving, and detail fidelity. The final choice of which plaster to use will depend on which properties are critical to the conservation task at hand. The results are given in tabular form.
