KWZ Fountain Pen Ink Glitter Firecracker

KWZ Glitter Firecracker belongs to the "All That Glitters" series – richly coloured fountain pen inks that suspend fine glitter pigments in a coloured carrier ink. Firecracker appears as red-orange with a golden shimmer: warm, vibrant and lively on paper. The ink is hand-mixed in Warsaw, Poland, and produced in small batches. Each bottle contains 30 ml in a brown wide-mouth glass jar.

Features

• Red-orange with golden glitter shimmer: The colour combination creates a warm, metallically shimmering impression on paper – particularly visible in raking light.
• Unique stabilisation technology: The glitter pigments settle significantly more slowly than comparable shimmer inks. This means: even glitter application across multiple pages, without constant shaking.
• Dye-based ink with pigment particles: The liquid component is dye-based and therefore flows well; the glitter particles are not water-soluble and create the metallic effect.
• Hand-mixed in Poland: Small-batch production by KWZ Ink in Warsaw – each bottle hand-filled and mixed.
• Wide-mouth glass jar: The brown wide-mouth glass allows direct filling of converters and piston fillers without any hassle.
• Not permanent: The ink is not water- or light-resistant and is not suitable for archival documents.

Use & Tips

• Shake before filling: Even though sedimentation is slowed – a quick shake before filling your pen ensures the pigment particles are evenly distributed in the ink and the glitter effect reaches its full potential.
• Nib choice: Stub nibs (medium and larger) allow plenty of ink to flow and bring the glitter particles into optimal effect. With a fine nib, the shimmer remains visible but appears more subtle – a controllable effect.
• Paper: On smooth, calendered paper with low absorbency, the ink stays wet longer and allows better alignment of the glitter pigments – the result is a more distinct metallic sheen. On absorbent copy paper, the ink dries faster and the effect is less pronounced, but still visible.
• Don't let the pen sit unused for too long: Since the glitter particles are not water-soluble, prolonged drying time in the feed can leave residue. Regular flushing with lukewarm water keeps the pen clean effortlessly.
• Control the effect intensity: Less shaking before filling produces a more subtle glitter application – ideal for those who prefer a lighter shimmer.

For Ink Enthusiasts

KWZ develops its glitter inks with a chemical approach that matches the particle size of the glitter pigments to their suspension in the carrier liquid. This structurally slows natural sedimentation – not through thickeners or viscous formulations that would compromise ink flow. The dye-based carrier thus remains thin and flows reliably even in finer nibs. KWZ Ink is led by Konrad Żurawski, who as a doctorate-holding chemist has been producing inks in small batches since 2012 – the "All That Glitters" line is his first dedicated glitter range.
