soaking veg tan leather ( grey lines appear)

Recommended Posts

so i noticed that when i have a clean looking piece of veg tanned leather.. i put some water on it and i get these odd grey lines and grey areas... like i rubbed it on newspaper or something.. i though i was maybe rubbing on something on accident or something like that... NOPE,  i tested it and got a clean piece and added some water  and right away the grey marks and lines appear.. is this normal?>  (ps, i noticed it on thin 2-3 ounce, not so much the 5-6 ounce)

Photos so we can see?

Grey or bluish?  If tends toward blue, then there is some iron contamination in the leather or due to a rack it was laid on.  You can bleach out with oxalic acid.  The colour is due to the same reaction as vinegaroon process.

it looks like the color is coming from within..... looks like newpaper was rubbed on it... but when it dries i think it goes away a bit... odd
