Tin Mordant – 1 oz. package
Use at ½ ounce per pound of fabric (3%)
Use at ½ ounce per pound of fabric (3%). Save the mordant bath and reuse by adding ¾ of the amount next time, (assume ¼ of what was added originally is still there). Some dyers like to add Cream of Tartar to the morant bath (10 %) to buffer the Tin, which can be somewhat acid, and to soften wool fabric. (When re-using Tin mordant bath, do not keep adding Cream of Tartar, as it isn’t absorbed into the fabric.)
Always wear gloves, such as dishwashing gloves, when working with any mordant.
