Discussion Overview

The discussion revolves around the use of white phosphorus, particularly in the context of friction matches and its properties when exposed to air. Participants explore how white phosphorus can be handled without igniting, its historical applications, and its chemoluminescent properties.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how friction matches can incorporate white phosphorus without igniting it upon contact with air.
  • Another participant suggests that keeping white phosphorus underwater prevents it from igniting due to lack of air exposure.
  • A participant raises the issue of how white phosphorus is mixed into match heads, proposing that wet pasta might have been used to expose the phosphorus only after drying.
  • Discussion includes the chemoluminescent properties of white phosphorus, with a participant noting that it glows in air without necessarily igniting, and questions how this was safely managed in historical contexts.
  • Several questions are posed regarding the historical use of white phosphorus in matches and its safety measures, including whether it glowed when exposed to air and if it was mixed with inert substances to prevent ignition.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the methods of handling white phosphorus safely, and multiple competing views exist about its properties and historical usage. The discussion remains unresolved with no consensus reached.

Contextual Notes

Participants reference historical practices and properties of white phosphorus but do not provide definitive answers regarding safety measures or specific techniques used in its application.

As long as it is under water it is not in a direct contact with the air, so it doesn't ignite.

From the same wikipedia article:

Lucifers were however quickly replaced after the discovery in 1830 by Frenchman Charles Sauria who substituted the antimony sulfide with white phosphorus.[15] These new phosphorus matches had to be kept in airtight metal boxes but became popular.
 
yeah, but how they mix in match head in the first place?
 
Perhaps they used wet pasta and the phosphorus was exposed when the mix was dried.

Plenty techniques that could be used.

I have another related question that doesn't involve matches.
White phosphorus glows on contact with air. This is a type of chemoluminescence, not fire. The greenish glow of white phosphorus was used for nineteenth century special effects. The chemoluminescence was there without full combustion.
The Sherlock Holmes story, "Hound of the Baskervilles" by Conan Doyle, uses white phosphorus in the climax. I am not sure, but I don't think this is science fiction. White phosphorus glows.
How did people, using the chemoluminescence of white phosphorus, prevent it from bursting into flame?
Maybe white phosphorus is only slightly flammable. However, I know how deadly white phosphorus can be in war. So maybe the owner didn't mind the risk to the dog. However, there must have been some safety precautions when using white phosphorus.
1) Did the first matches, which used white phosphorus, glow green when exposed to air?
2) Did people using the chemoluminescence of white phosphoruse just keep it away from flame?
3) Did people mix white phosphorus with some inert substance that prevented flame?
