Diamine Raw Sienna is an unsaturated, yellowish, light brown, dye based ink. It’s from Diamine Inks standard range.
Sienna is an earth pigment containing iron oxide and manganese oxide. In it’s natural state it is yellow-brown and is called raw sienna. When heated it becomes a reddish brown and is called burnt sienna. Along with ochre and umber it was one of the first pigments to be used by humans.
I found it quite a well-behaved ink ink to write with. It exhibited some nice shading, flowed well and lubricated the nib quite smoothly across the page.
