beltbuckles Report post Posted October 13, 2017 (edited) 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) Edited October 13, 2017 by beltbuckles Quote Share this post Link to post Share on other sites
Northmount Report post Posted October 13, 2017 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. Tom Quote Share this post Link to post Share on other sites
beltbuckles Report post Posted October 13, 2017 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 Quote Share this post Link to post Share on other sites
