ABSTRACT OF THE DISCLOSURE Manufacture of grain and split leather is simplified by pre-tanning hide with a chromium-free tan until its shrinkage temperature is about 170 to about 185°F, splitting the pre-tanned hide to provide a grain intermediate and a split intermediate, shaving at least one of these intermediates, and chrome- tanning the shaved intermediate. Shavings contain no chromium and can be disposed of by dumping, without significant environmental impact. Before splitting, the hide can also be pickled to improve the splitting and shaving and make the unfinished hide better suited for shipping to remote geographical areas. Entire hide treatment sequence can be effected with two stages in which batches of hides are loaded in a container such as tumbling drum; unhairing, bating and pre-tanning with or without a pickle, all in one stage, and final tanning, coloring and fat-liquoring in another stage. Final chrome-tanned product has very good physical characteristics including unusually high slot tear and is recovered in higher yield.
