Category: Ink Loading

Ink Loading encompasses the precise mechanical methods of transferring liquid calligraphic media—via disposable cartridges, twist-piston converters, eyedropper conversion, or reservoir dipping—into the writing instrument without introducing disruptive airlocks or messy spills.

Fluid Dynamics: Surface Tension, Hydraulic Seal & Priming Physics

Loading ink into a writing tool is a controlled hydraulic operation. When a piston converter draws ink upward, it creates a partial vacuum that pulls fluid through the feed’s collector fins. To achieve a complete 100% capacity fill, the nib must remain fully submerged beneath the ink surface until the piston stroke finishes, followed by releasing two drops back into the bottle and turning the piston slightly back to clear the feed collector of excess saturation.

For traditional dip pens, ‘dipping’ directly into a bottle often loads too much ink, leading to accidental blobs. Master calligraphers frequently employ ‘brush loading’—using an ordinary watercolor brush or eyedropper to apply ink directly onto the underside of the nib reservoir. This provides exact volume control, extends writing duration, and prevents dipping accidents.

Frequently Asked Questions

What should you do if an ink cartridge won’t puncture?

Ensure you are inserting the narrower end of the cartridge directly into the feed nipple. Press firmly and straight down against a stable desk surface until you hear or feel a distinct snap.

Can you refill empty plastic ink cartridges with bottled ink?

Yes! Clean out the empty cartridge with a blunt-tip syringe and water, let it dry, and use the syringe to refill it with any fountain pen ink of your choice.

Why does ink leak into the cap after filling with a converter?

After filling via a converter, the feed is oversaturated. Always release 2 to 3 drops of ink back into the bottle and reverse the piston screw slightly to create an air buffer that prevents cap flooding.

Can you use calligraphy dip pen ink inside a fountain pen converter?

Never. Bottled inks labeled ‘Calligraphy Ink’ or ‘Drawing Ink’ often contain shellac or acrylic binders that harden into waterproof plastic, permanently destroying converter mechanisms and feed capillaries.
