There are a lot of facts on this page that aren't referenced (dictionary.com definition that was referenced has none of the dates or other info). Bfesser 03:22, 23 February 2007 (UTC)

I edited the paragraph on Field. Some changes might still be needed, as the statement: "By 1804, the English dye maker George Field [...]. Over the following years, it was found that other metal salts, including those containing iron, tin, and chromium, could be use in place of alum to give madder-based pigments of various other colors." might be incorrect. The addition of other metal salts seems more like the typical re-discovery of something that was in use in the past. Giuliano. HumphUK 14:07, 5 September 2007 (UTC)

Also, why is madder lake redirecting to Alizarin? Madder lake should have an entry on its own with pictures (I have some nice ones if necessary). Giuliano. HumphUK 21:07, 6 September 2007 (UTC)
