Fountain Pen Ink
Night owl is based upon an owl eyes through the trees at night. This exquisite orange is highly saturated with a gold sheen on good quality fountain pen paper. This ink is fairly wet writing and very well behaved in almost any fountain pen.
Surface Tension: 40.1mN/m
What is this?Surface Tension affects the flow of an ink through a pen, and how quickly it is absorbed into paper. Ink with a high surface tension generally flows and dries slowly, while a low surface tension causes faster flow and dry time, but can cause ink to gush, and also feather or bleed. Water has a surface tenstion of 72mN/m. Most inks are in the range of 40-60mN/m
pH: Data Coming Soon
What is this?The pH of an ink defines it's alkalinity or acidity. The pH is important for the dye in the ink to achieve the correct colour. Inks with a pH between 6.5 and 8.5 are generally neutral and safe to use in all pens.
Saturation: Very High
What is this?The saturation of an ink is the percentage of pure dye content in the mix. Generally but not always, higher saturation increases sheening and decreases shading, while also improving flow wetness but causing slower drying time. Very light inks can have as little as 2% dye content, while extremely saturated inks have upwards of 20%.
What is this?The sheen of an ink is the secondary, often shiny colour that appears when the ink is swatched heavily or pools in script. The sheen colour depends on the specific dyes in the ink, while the intensity depends on the saturation of dye. Some inks will never sheen, while some will sheen on almost any paper in any amount.
What is this?Shading is an ink's ability to create a range of different tones, from light to dark, depending on how heavily it wets the page. Generally but not always, inks with a lower saturation of dye are more effective at producing shading effects, but the kind of dye used also impacts this.
What is this?Shimmer is a pigment added to inks to create a sparkly effect. There are a wide variety of shimmer forms and colours, each with its own qualities. Most inks contain no shimmer, and those that do can contain shimmer in differing quantities. Highly shimmered inks do carry the potential of clogging pens, especially ones with finer nibs. Van Dieman's only uses extremely high quality shimmer pigments that lower (but do not completely remove) the risk of this.
Flow Wetness: Wet
What is this?This, quite simply put, is how well an ink flows through a pen, but also dictates how quickly an ink will seep into a page. Flow is affected by both the surface tension and saturation of an ink, but also by other additives such as humectants and surfactants. Inks with a high flow wetness can sometimes, but not always, feather and bleed more than other.
