Paper & pairing
Browns tend to photograph and scan a little darker than they look in person — worth testing before using one for anything that will be digitized. Sheening inks need the right conditions to show off — a wetter nib and a coated, less-absorbent paper (Tomoe River and similar sheets are the community standard) let the ink pool slightly and separate into its second color as it dries. On cheaper, more absorbent paper the sheen effect will mostly disappear.
About Birmingham Pen Co.
Birmingham Pen Co. is a two-person American ink and pen manufacturer from the Pittsburgh, Pennsylvania area, originally based in a warehouse on the Monongahela River in Pittsburgh's Southside and now located in Cranberry Township. The name honors the Southside's old nickname 'Little Birmingham', a nod to Birmingham, UK, the historic center of pen and nib manufacturing. The company hand-produces small batches of fountain pen ink in distinct in-house formulas such as Keystone and Everlasting.
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight — most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
