Tools: weights, iron pot, burner, tripod, chemical pliers
Chemicals: tin, bismuth, lead, cadmium
Procedure: dare one gram of tin, bismuth 3.5 g, 2 g of lead and 0.5 g of cadmium. Everything we put in an iron crucible, melted and let cool. We have prepared alloy
called Wood's metal, which has a melting point of 66 ° C. This metal softens and melts in a glass
such as hot tea.
Wood's metal is composed of 50% bismuth, 28.5% lead, 14.3% cadmium and 7.2% tin.
Metal alloys having different physical properties than the pure metals.
This mixture is called eutectic
