Hello again.
I'm nearly finished my madder chamois project. I've just got one last question:
I understand that after taking the material out of the dyebath, you're supposed to let it dry, and then wash it to remove any unfixed dye and pieces of root. Should you use soap/detergent, or just plain water?

I would use just plain water. Soap/detergent might strip some essential "something" from the leather. Just rinse and repeat if necessary sounds safer to the leather.

Rinse it with clean water till it runs clear, if it turns out a little stiffer then you would prefer roll it for a while and it will soften up.
You shouldn't need to let it dry before hand, any dye that hasn't fixed will wash out when you rinse it either way....
Never use detergent on leather, saddle soap is fine....

Treating it once dry to a good leather fat will darken it somewhat, it may be greasy to start with but after a few days this should largely go away as the leather takes up the fat, will also add some water proofing.
The lighter more fibrous side as you say is likely the flesh side its quite normal...
A second dying may well increase the depth of the colour also, as likely you'd reached the maximum the mixture would allow and exhasted the dye bath...

I had considered throwing it back in the same bath, but you're probably right; if it wasn't taking up more color already, then there probably wasn't much left to take up. Anyway the bath was developing a nasty-looking skin, so I dumped it a couple days ago.
What sort(s) of fat would you suggest, and how much? I've never applied oils or dressings to suede, so I don't know how treat it without making it tacky.

I use "Effax Lederfett" (leather grease) on all leather it helps to bring out the colour apply it a bit at a time with your hand and rub it in the warmth of your hand will help the leather absorb it keep going untill its completly absorbed, probably any good natural leather fat from a tack shop will do... it must be totally natural ingredients though, different kinds of oils and fats combined nothing synthetic.
You can clean the leather with leather soap.

Thanks. Though with all the ongoing projects and school coming back up, I'll probably be reading that until the end of the year!

You may also find this interesting, deerskin "tanned" with fish oil(cod) the dying is done by spreading the natural colorant over one side, according to the blurb aldehydes are created by oxidation of the oil making a more or less permanent tann:

videos about the process in German:

They claim to be the last using this process in Germany, which given that it takes a year doesn't surprise me.

German buckskin is nice stuff. That's what I made my second gorytos out of. Its properties are just like chamois, except much thicker, so presumably it'd take up dye and dressing the same way. They say it's also very similar to braintan (which is something I unfortunately still haven't examined firsthand) and some of it is sold lightly-smoked for use in Native American crafts, even though it doesn't need smoking.
