The literature relative to the investigation was reviewed and criticized. Iron pyrite was added to clays in amounts varying from 0 to 5%. Test pieces 2×2×41/2 inches were fabricated by the stiff‐mud, and dry‐press processes. After firing to cone 8 these were subjected to load tests at 1350°C under oxidizing, neutral, and reducing conditions. Expansion and contraction values were plotted against time and temperature. Results under reducing conditions. Expansion and contraction increased with increase of pyrite content.
