  Antimony Trisulfide

  8,99 € – 21,99 €

  Name: Stibnite, Antimonite, Antimony sulfide/sulphide, Antimony (III) sulfide/sulphide
  Chemical formula: Sb2S3
  Particle size: fine powder

  Description: Antimony trisulfide is a green powder. It is a fuel used in various white star compositions of the potassium perchlorate-base. It is sometimes used in glitter compositions, fountain compositions and flash powder, however it is used less and less for flash powder as it is very poisonous and can usually be replaced by sulphur or completely omitted. Flash compositions containing antimony trisulfide are very sensitive to friction, shock, and static electricity

  Precaution:

  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 Carbonate

  4,99 € – 38,99 €

  Name: Barium Carbonate, Barium monocarbonate, Carbonic acid barium salt
  Chemical formula: BaCO3
  Particle size: very fine powder

  Description: Barium carbonate is used both in white and green color compositions. When chlorine donors are present in a composition a green color will result from the formation of BaCl+ in the flame. Without chlorine donors BaO will be formed which emits white light. Barium carbonate is convenient to use in chlorate based color compositions since it will neutralize residual acid which reduces the risk of spontaneous ignition

  Charcoal Pine

  9,49 € – 57,99 €

  Name: Charcoal pine
  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
