Fountain Pen Ink Compatibility Chart: A Guide for Enthusiasts
Choosing the right ink for your fountain pen is crucial for performance, longevity, and writing pleasure. With countless brands and formulations available, understanding ink compatibility helps prevent clogs, corrosion, and poor flow. This guide provides a quick-reference chart and essential tips for selecting the best ink for your pen.
Why Ink Compatibility Matters
Not all fountain pen inks are created equal. Some contain pigments, shimmer particles, or acidic formulations that can damage feeds, clog mechanisms, or stain pens. Using incompatible ink may void warranties or require deep cleaning. Always check manufacturer recommendations before filling your pen.

Key Compatibility Tips
- Check manufacturer guidelines: Brands like Montblanc and Pelikan often recommend their own inks.
- Avoid mixing ink brands: Chemical reactions can cause sedimentation.
- Clean regularly: Flush pens every 4–6 weeks, especially with pigmented or shimmer inks.
- Test first: Use a dip test or cheap pen before filling a prized collector’s item.
Conclusion
Understanding ink compatibility ensures smooth writing and extends your pen’s lifespan. Stick to dye-based inks for worry-free use, and reserve specialty inks (pigmented, shimmer, iron gall) for pens designed to handle them. When in doubt, consult your pen’s manual or retailer for guidance.
Happy writing!
