American Dental Association Health Foundation Research Unit, National Bureau of Standards, Washington, DC 20234 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°C. Brewster amalgam stored for five yr in air expanded 186, 68, and 14 µm/cm at 60, 37, and 23°C, respectively. Nearly "stable" conditions were approached at about 50 mo.
