Red in the bottle, a medium rose-shifted grey when wet, and mildly tarnished silver when dried on (most) paper, expect the unexpected with Sterling Silver. This heirloom inspired hue may present materially different relative to paper type, saturation, and lighting. Photographed color swatch was produced with cotton swab on Tomoe River paper.

Featured writing ink is designed for a fountain pen paired with common quality writing papers. The 90mL volume delivers approximately 112 standard converter refills with a 0.8mL draw. We manufacture this product in Pennsylvania with domestic and imported ingredients.

A Chemistry Of Color

How It's Made

Our fountain pen ink formulas are developed in-house using fine colorant and a meticulously tuned vehicle. Every bottle reflects our commitment to performance, value, and creative exploration.

Formula Guide

We've compartmentalized our fountain pen ink recipes into four principal categories characterized by differentiating elements of the colorant component in the formula. A colorant is a dye or pigment that exhibits color. An ink vehicle is a series of chemicals used to transport colorant from storage reservoir to substrate (paper in our case).

Keystone Formula inks are engineered using water-soluble dyes to produce a broad spectrum of colors with a variety of unique and desirable writing properties. Fitting the bill for a traditional fountain pen ink, this series by far the most popular.

Delicate Formula inks are constructed with dyes selected for both performance and washability. Colors in this series will clean easily from most fabrics and surfaces with soap and water.

Everlasting Formula inks are compounded with pigmented colorants to produce highly water-resistant and archival properties on most papers.

Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.

Sample Recipe

This ink is part of our Atomink Element line, a series of foundational hues specifically crafted for blending.

Use this color independently, or mix it with other Birmingham Pen Co. inks to produce our recipes or your own custom shade.
