[edit] Clarification

The article doesn't seem consistent. First Phlogiston is described as being weightless, and then metals should lose weight when the phlogiston has been burned up.

There were many variations on the phlogiston theory, as people tried to correct some of the problems. For example, see http://books.google.com/books?q=phlogiston+intitle%3Ashort+intitle%3Ahistory+intitle%3Achemistry , particularly around page 88 (you may need a google account). Ideally, this article should be expanded to mention the variations and attribute them to their respective proponents. Itub 15:37, 22 December 2005 (UTC)
