  Boric Acid

  2,99 € – 8,99 €

  Name: Boric acid
  Chemical formula: H3BO3
  Particle size: crystaline fine powder
  purity: 99% With anti-caking (easier handeling)

  Description: Boric acid is a white powder which is used as an additive to compositions containing aluminium and a nitrate. The metal powder can reduce the nitrate to an amide, which will react with the metal powder in a very exothermic reaction that can lead to spontaneous ignition of the composition. This process is often accompanied by a smell of ammonia and is most likely to occur with wet compositions. Addition of a few percent boric acid can often prevent this reaction from taking place since it neutralizes the very basic amides forming ammonia and a borate. It is also advisable to avoid using a water-soluble binder for these compositions. Using red gum or shellac with alcohol or nitrocellulose lacquer is safer. Boric acid is hygroscopic. The use of boric acid with magnesium or magnalium is not advised, as it actively attacks and corrodes these metals.

  Barium Sulfate

  4,49 € – 34,99 €

  Name: Barium sulfate
  Chemical formula: BaSO4
  Particle size: very fine powder

  Description: Barium sulfate is used as a high temperature oxidizer in some green and white compositions, as well as being the oxidiser in the flash phase of some strobe compositions. It is also used as an additive in many firefly star compositions. Barium nitrate is more common in green pyrotechnic formulas, as it is a more amiable oxidizer and produces a superior colour

  Charcoal Oak

  9,49 € – 57,99 €

  Name: Charcoal Oak
  Chemical formula: C
  Particle size: very fine powder
  purity: 99%

  Description: Charcoal finds widespread use in pyrotechnics. Many types of charcoal exist, each with its own properties. It is a complex organic substance containing moisture, ash, carbon, hydrogen, oxygen and a variety of volatiles. All of these elements have a vital use in fireworks. Charcoal made from willow or grapevine is considered great for black powder, while hardwood charcoals e.g. pine charcoal are commonly used for spark effects. The particle size and the process used to make the charcoal also play an important role in the quality of the charcoal for a specific purpose. Very fine charcoal floats in air and is therefore sometimes referred to as ‘airfloat’. Because charcoal is a very important chemical it is listed in the Beginners’ pages
