Ink Review # 258

🧾 Description

 

Ink: Sea Color / 海色 Hǎi sè 

Brand: Jinchen

Country: China

Bottle size: 18 ml

Pens Used: Kaweco Sport Navy (EF, F, M, B, BB, 1.1, 1.9), Hongdian Forest Gold Fude, Ahab with a FPR ultra-flex nib.

 

This was another impulse buy. The ink is a lovely light petrol blue with a hint of pink/red chromo-shading with BB, 1.9 stub and fude nibs on most papers.

 

The ink is wet, with acceptable but below average lubrication. Despite its wetness it struggled with the flex nib and the colour became more saturated and all chromo-shading effects disappeared. 

 

I believe this ink could shine with brush pens. 

 

I most enjoyed drawing with it and ink washes were a dream. 

 

Overall, an ok ink if you’re into calligraphy or drawing, but if you write mostly with F nibs and finer, you won’t enjoy it.

✍️ Writing Samples (photos LED only and closeups) 

JEF stands for Japanese EF nib.

Translations from language are provided for reference only and may differ from published versions.

For some reason the color is not right with Kaweco EF to M nibs. I believe my pen might have been wet, hence this weird teal color.

 💬 Closing

 

This is lovely blue ink, which in my opinion is best with BB and above nib. 

 

No fountain pens were harmed in preparing this review. 😉
