Talk:Vat dye

Contradiction
The article seems to contradict itself about what types of dyes are used for vat dyeing. Clarification is needed.

It looks like most of the article was copied verbatim from a web page about vat dyeing (http://www.pburch.net/dyeing/vatdyes.shtml), including a paragraph about diifferent dyes for vat dyeing that made perfect sense in context but makes no sense at all in an entry specifically about vat dyes.

Disambiguation needed
Vat dyeing = dyeing using a bucket ("vat") Vat dyestuff = a dyestuff which is applied in its "leuco" (reduced) state and as it oxidizes with air oxygen, the colour develops. Anthraquinone vat dyes are the most important group of vat dyestuffs. — Preceding unsigned comment added by 62.2.135.162 (talk) 14:45, 26 March 2013 (UTC)
