[edit]The first paragraph is a statement of what zinc pest is. I will delete the scientific explanation, which is all that was cribbed from http://www-personal.umich.edu/~khmiska/zinkpest.htm. Hopefully a metallurgist will find this article and flesh things out. The second paragraph is simply a summary of what is widely known among collectors of radios, toys, and other die-cast objects.

It seems that all this is unwarranted. The Kinslayer, who put the speedy-deletion tag here said the following on his talk page shortly after I asked him why he removed the tag. Frotz 10:39, 6 March 2007 (UTC)
- I was mistaken in placing it in the first place, as it turns it out that it didn't actually constitute a copyvio as it was :re-worded. The Kinslayer 10:33, 6 March 2007 (UTC)
- May we know what the scientific explanation for zinc pest is? Presumably there is some chemistry going on. Could some friendly chemist explain it please? 31.52.252.179 (talk) 18:05, 21 November 2013 (UTC)
- Impurities, typically iron, precipitate slowly into the boundaries between the crystalline grains of the zinc alloy. The grains no longer fit together and are pushed apart by these precipitates, leading to the distortion and cracking. Andy Dingley (talk) 19:33, 21 November 2013 (UTC)
NB: pest means roughly "plague" (as in The Black Plague, Yersinia pestis, also for other infectious or parasitical ailments which spread easily and are hard to cure/destroy: Schweinepest, Zinnpest) It does not primarily mean pests (animals you don't like) as in "those bugs that are eating my potatoes" —Preceding unsigned comment added by 145.253.2.234 (talk) 09:27, 14 September 2007 (UTC)
