Bismuth is a rare low-melting-point metal. It is commonly used in fire detection systems, electrical fuses, stomach medicines, cosmetics, pigments and bullets. But we use it in jewellery. The oxidation of bismuth is spectacular, where natural crystalised forms and colours can tell us the temperature.
 
One colour represents one temperature, so it makes each piece exceptional.
