Scabiosa does not. Iron gall inks bond chemically with paper fibres as they dry, and then continue to oxidise — the iron in the formulation reacting with oxygen to deepen and shift the tone. Freshly written Scabiosa is a soft dusty purple-grey. After a week it is darker. After a month it has settled into its permanent colour — a complex, warm grey with purple undertones that could not have been predicted from the wet ink. This is not inconsistency. It is the defining property of iron gall, and why manuscripts written in iron gall five hundred years ago are still perfectly legible.\u003c\/p\u003e","brand":"Rohrer \u0026 Klingner Salix","offers":[{"title":"Default Title","offer_id":53230665859400,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/inkwellartsupplies.com\/products\/rk-scabiosa-iron-gall-ink-50ml","provider":"Inkwell Art Supplies","version":"1.0","type":"link"}
