Summary
Tin soldiers, approx. 65 mm (2 1/2") high, being cast in German molds from the early 20th century. The two mold halves are clamped together, and the metal (an alloy of tin and lead, heated to approx. 300°C / 570°F) is poured into the mold. When the metal has solidified, the mold is cracked open. Sprues (pouring channels) and extraneous flash (metal that has penetrated cracks and air channels in the mold) are seen in the third image, and have been removed from the castings in the last image.
