I think that's correct. When I was a student in England years ago, we used to buy a liquor known as Polish White Spirits, which was 180 proof or 90 percent. The local wisdom (university students) held that anything stronger would promptly dilute itself back to 180 proof from water in the air (this was England, remember, very humid). Google tells me that one can buy 190 proof (95 percent) "Everclear" grain alcochol in British stores today. Blue skies! -- Dan Ford (Proof = the concentration of alcohol at which gunpowder soaked with it will still explode, or rather flash up. It was therefore called "proof", which later became 100 proof. It just happened to be 50 percent alcohol, so 200 proof is 100 percent. (More student wisdom.) (Wiki tells me that 100 proof is actually 49.28 percent alcohol BY WEIGHT. By volume, it's less, so the student wisdom is a bit shaky.) Blue skies! -- Dan Ford Claire Chennault and His American Volunteers, 1941-1942 forthcoming from HarperCollins www.flyingtigersbook.com |
