THE BEST
GRADE OF TANNING

The grade of tanning (i.e. the measure of how effectively the leather is tanned and stable) of a leather is evaluated by its "Tg" which corresponds to its shrink temperature (or gelatinization). The Tg needs to be at least 65-70 because if less, durability cannot be assured. Nuti White Leather is the only metal-free tanning that has reached and often surpasses a Tg of 75.
