Known chemically as Pigment Blue 27, it has haunted the painter's palette under a dozen aliases ever since—Prussian Blue, Paris Blue, Milori Blue, and Berlin Blue. Yet, despite its heavy, bodily origins, it is a notoriously temperamental material. PB27 demands a strictly pH-neutral environment. Introduce this pigment to harsh acids, caustic alkalis, or high heat, and its complex chemistry simply collapses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCaution: \u003c\/strong\u003eHighly dispersive and aggressively staining.
