Barium peroxide: oxidizer. A precursor for hydrogen peroxide. Mixed with magnesium powder and lit with a magnesium ribbon it will ignite thermite (mix 1.7 g barium peroxide with 0.2 g magnesium powder).

Thermite: 76.3% iron II oxide (black), 27.3% aluminum powder. Note that Iron III oxide also works, though

To make the military version Thermate create a mixture of 68.7% thermite, 29.0% barium nitrate, sulfur 2.0%, and dextrin 0.3%.

stock

  • boric acid B(OH)3
  • polydimethylsiloxane
  • WEP (Water Extended Polyester)
  • ethylene glycol
  • propylene glycol
  • glycerol
  • diethyl ether

acids

  • Nitric acid - HNO3
  • Sulfuric acid - H2SO4
  • Hydrochloric acid - HCl
  • Phosphoric acid - H3O4P
  • Hydrofluoric acid - HF: Hydrofluoric acid is extremely dangerous. It is toxic on contact. Initial contact is painless and may be unnoticed. Toxic results are slow to take effect, but difficult to treat once results become evident. See Boric acid for antidote. Consumer quantities are fairly easy to obtain in concentrations of about 4% (still dangerous). Useful in etching glass (even a 4% solution is effective for this). It can dissolve glass without leaving an etched surface; the surface is left smooth. It is useful for decapping integrated circuits.
  • Boric acid - BH3O3: Useful as an antidote to hydrofluoric acid contact.
  • Formic acid - CH2O2
  • Carbonic acid - H2CO3: Formed when carbon dioxide dissolves in water.
  • Acetic acid - CH3COOH (also written as CH3CO2H or C2H4O2): When undiluted it is known as glacial acetic acid. Vinegar is 3 to 18% acetic acid (the remainder is mostly water).
