Bismuth(III) oxide is perhaps the most industrially important compound of bismuth. It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. Bismuth trioxide is commonly used to produce the 'Dragon's eggs' effect in fireworks, as a replacement of red lead. References: Schmidt S, Kubaski ET, Li MS, Bezzon VDN, Sequinel T, Tebcherani SM.
