Frequently Asked Questions
Will black fountain pen ink ruin my clothing if I spill it?
Most black fountain pen inks are water-soluble dyes and will likely stain fabric permanently. If you spill ink on a shirt, treat it immediately with a cold water rinse and a dedicated ink-removing soap. Do not use hot water, as heat often sets the dye into the fabric fibers. Using a specialized cleaner is your best bet for saving your favorite outfit.
Can I mix different brands of black ink together?
You should generally avoid mixing inks from different manufacturers unless you know the chemical composition of both. Some inks have different pH levels that can cause the mixture to sludge up or create solid particles inside your pen. If you decide to experiment, mix a tiny amount in a separate vial first. Let it sit for 24 hours to ensure no chemical reaction occurs before putting it in your pen.
How long should I wait before cleaning my fountain pen?
If you use your pen every day, you can go a month or two between cleanings. However, if you plan to store the pen for more than a week, you should flush the nib to prevent the ink from drying out and clogging the feed. A quick rinse with distilled water is usually enough to keep things running smoothly. This prevents the ink from forming a crust that restricts flow.
Why does my black ink look gray on the page?
This usually happens because the ink is either too dry or the paper you are using is highly absorbent. A highly absorbent paper acts like a sponge, drawing the ink deep into the page and making the color appear washed out. Try using a higher-quality paper specifically designed for fountain pens. Alternatively, look for a more saturated ink, which contains a higher concentration of dye for a darker appearance.
Is it safe to use black calligraphy ink in my fountain pen?
Never put calligraphy ink or India ink in a fountain pen. These inks contain shellac or acrylic binders that will harden inside your pen and permanently damage the delicate internal feed system. Only use inks specifically labeled as fountain pen ink. These are formulated to stay liquid and flow properly through the narrow channels of a fountain pen nib.
