...TREASURY OF AMERICAN POLITICAL HUMOR by Leonard C. Lewin. These jokes and yarns tend to be on the broad side, but in addition to being funny, they provide perspective on our most revered -and often clumsiest-political customs and institutions...
Pulp & Chlorine. To brominate wood pulp, Dr. Lewin simply adds sodium bromide, which is as stable as table salt, to the solution in a standard bleaching apparatus, then bubbles chlorine through it. The combination of chemicals releases active bromine in a form that attaches itself to the lignin in the pulp. Treating solid wood is a more complicated process, but the results are spectacular. When a piece of brominated wood is put in a hot fire, it does not burn. After a while, a layer of carbon forms on its surface, but carbonization stops as soon as the wood...
...studies, Dr. Lewin does not yet know in detail how bromine fireproofing works, but in general the action is connected with the way that wood burns. When heat is applied to natural lignin and cellulose, they give off combustible gases that form flames and spread the fire by heating more wood. Somehow, bromine seems to make those gases nonflammable. And with no flames to spread it, combustion stops as soon as the external heat source, such as a lighted match, is removed...
