[Histonet] Question concerning stain production[Scanned]

[Morken, Tim - Labvision]

Concerning how the oldtimers stumbled on dyes, you should look into the
textile dyeing industry. This website is a good start. It tells the history
of logwood and brazilwood, from which hematoxylin and brazilin dyes were
made.

Subject: [Histonet] Question concerning stain production[Scanned]

Hi all, im new to this list.

Ive been searching this list for production of
different stain types but didnt find anything. Perhaps
my question has been taken up before or is so
ridiculously simple that its laughable, so id like to
apologise in advance if anyone is offended or
disturbed by my questions.

Id like to know if there is a possibility to, with
simple, easy obtainable chemicals and raw materials
produce the most common stains that are avaliable.
Anything from Methylene  Blue, Eosin, Haematoxylin,
Orange G etc. I mean how did the old guys like Koch or
Ehrlich produce them or stumble upon them anyway? 

Thanks in advance
