The chemistry behind the effects

Svea fireworks have, with the environment in mind, replaced all lead with vismut oxide in all our fireworks. The main propulsion in all fireworks is black gunpowder, pure or in a mix with other chemicals. The colors in the fireworks are created through metallic salts. Up to the beginning of 19th century the effects where solely white or gold colored, but the technique of using metallic salts created the specter of colors that makes fireworks in many facets a colorful show.
