title: Dimensional changes of a high-tin content amalgam.
abstract: Amalgam made with Brewster Alloy (62% Ag, 33% Sn, 5% Cu, and 0.2% Zn) had little or no dimensional change during 24 h at 23 degrees C. Brewster amalgam stored for five yr in air expanded 186, 68, and 14 microns/cm at 60, 37, and 23 degrees C, respectively. Nearly "stable" conditions were approached at about 50 mo.
