Which staining protocol uses Bouin's as a post-mordant to enhance staining?

In Masson Trichrome, the goal is to distinguish collagen from muscle and cytoplasm by staining them different colors. After the initial dyes are applied, Bouin's solution is used as a post-mordant to intensify the blue stain of collagen. The picric acid in Bouin's helps dye binding and tissue differentiation, producing a strong, crisp blue for collagen and clear contrast with other tissue elements. This makes fibrous tissue and fibrosis easier to evaluate. Other staining protocols don’t rely on Bouin's post-mordant for their characteristic contrasts: Hematoxylin and Eosin use a different sequence without Bouin's, Congo Red targets amyloid with its own specific steps, and Oil Red O stains lipids in frozen sections in a way that isn’t compatible with Bouin's mordanting.
