White crystal like powder after black dye on leather

[HenriqueNarciso]

Hello,

I've dyed my leather with aniline black dye dissolved in water. after it dryed some of the pieces presented a crystal like white powder. This happened in the second and third dying process.

Has anyone come across this issue? Can I just wipe the powder and apply the finish(aquos lacquer)?

thanks in advance!

What water did you use?  Could be dissolved minerals in hard water ... if that's what was used.  If so, get some distilled or demineralized water and wipe it down a few times.

And for the future, the results would be better if a dye that was specifically formulated for use on leather is employed as it takes all of the inconsistencies and potential issues from lesser products into consideration.  It does appear that the water was most likely very mineral rich but it also appears that the dry dye mix was not totally dissolved.  What type of dye mix did you use?  If the dye mix used is intended for use in the coloring of fabrics then that would explain a lot; it is intended for CLOTH fabric, not leathers.

What type or tanning was the leather. Curious regular veg tan ?

Hi all!

yes I used tap water. got the message :D next time distilled water it is :D

I did buy aniline dye from a leather resealer and it was gross sold as leather dye. I dissolved it with hot water, this time around I didn't even add cold water, it was almos 1 litter of boiled water into a portion of black aniline dye (50 grams I would say). I couldnt find anywhere the portions to water ratio.

It was raw leather . since I'm a newbie I dont know what is the diference between veg tan or other.

anyway, I wipped the white powder of and gave it a finish, lets see how it turns out.

thanks!
