Brass zinc, especially between the Islamic and Byzantine world. Conversely the use of true brass seems to have declined in Western Europe during this period in favour of gunmetals and other mixed alloys but by about 1000 brass artefacts are found in Scandinavian graves in Scotland, brass was being used in the manufacture of coins in Northumbria and there is archaeological and historical evidence for the production of calamine brass in Germany and The Low Countries, areas rich in calamine ore. These places would remain important centres of brass making throughout the medieval period, especially Dinant. Brass objects are still collectively
Wood's metal Hot baths with Rose's and Wood's metals are not in routine use but are employed for temperatures above 220 °C (428°F). Wood's metal has modulus of elasticity 12.7 GPa and yield strength 26.2 MPa. Wood's metal is toxic because it contains lead and cadmium, and therefore contact with the bare skin is thought to be harmful, especially in the molten state. Vapour from cadmium-containing alloys is also known to pose a danger to humans. Cadmium poisoning carries the risk of cancer, anosmia (loss of sense of smell), and damage to the liver, kidneys, nerves, bones, and respiratory system. Field's metal
