Aqua Regia.  Mixture of concentrated hydrochloric and nitric acids, capable
of dissolving gold.  I could find the exact proportions, if you wish.

But while lye is certainly caustic, it equally certainly isn't acid. In
fact, it's base. Extremely so. Don't know Aqua Regia.

I think it is possible that when  Stefan asked about acid, he did mean
specifically acid...

I'm pretty sure some mordants used are acid. When dyers in period used
urine, modern dyers commonly use uric acid... I don't really know a lot
about this, but it would be a place to look.
