Teacore leather jackets - post yours here!

[MrProper]

I suspect the "tea core" effect on older jacket is the result of bone yellow or grey core from hasten drum dyeing like Canuck said, and then with exposure, than faded part become brown from oil exhaust or dirt and grime and oxidation and UV tanning or combination of all those, who dyed leather tan and then overdye it with black in the old days??, people in the old days don't like faded leather, they just come to accept it while waiting until they can afford to buy new jacket, the same with jeans, nobody like dirty faded jeans in old days, people just come to accept it as workwear and replace it from time to time, only since the 80's people started to get creative with bleach and pre faded denim, and only recently "tea core" is a thing to pursue in leather as the equivalent of sick fades on leather like it's on raw denim.

That reads plausibly and makes sense. The question is... was it really like that or is that just an assumption? It should be possible to check this using really old jackets. Perhaps there were reasons for a brown core. E.g. a large batch of brown for brown jackets and then dye a few so that you can also offer black from the same batch? Also just speculation.

That is what I was thinking. Some of the brown core in these jackets is really vibrant brown; doubt it became like that from grime and wear of chrome blue. Chrome blue becomes whitish, no matter the age. I think a batch of brown hide with a black topcoat is more likely.

Shinki SF Horse, probably more than 2 months of wear here and there.

does this mean what modern tanneries' teacore is authenthic?

or the old leather probably has been treated by conditioner several times over the decades that get absorbed and accumulated into the core and change the blue hue of the hide due to oxidation or just the conditioner has a color and accumulated? I read somewhere mink oil would tend to make the leather to develop red hue patina, while beeswax tend to make the leather to develop amber hue patina, and neatsfoot oil will develop brown hue patina.

I would lean more towards it being veg tan originally or just a struck thru brown than a chrome tan with magical color changes.

If it was conditioner you'd think there might be uneven areas like the inside of hems that kept the 'original color' etc but I've never seen it not be even.

I don't think this jacket was ever treated with conditioner before I got it.

Is this considered teacore? Or natural / bone core
