His model for discussion, indigo, is based on Saxon blue rather than on a traditional vat as it was in the earlier presentation. reference This is especially important because de la Follie developed several new dyeing processes that employed oil of vitriol — a critical component of the Saxon blue vat.
For use as a coloring material, the indigo is placed into an alkaline solution, which again turns it green.
