Why vegetable tan and chrome tan feel different

Bark tannins fill a hide into firm, moldable leather, while chromium salts leave it softer and more willing to stretch.

From the opening

Vegetable-tanned leather is collagen filled and linked by plant tannins, so it tends to feel firm, dense, and able to hold a tooled shape. Chrome-tanned leather is linked by chromium salts, and it tends to feel softer, emptier, and more willing to stretch. The opening covers tannins add body to the hide, chrome links stay small, and vegetable tan can be wet-formed.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
