Jack Frost, by Diamine

Terribly out of season maybe, but it doesn't  make the color less beautiful. Recently Diamine released  colors of their 2019 invent calendar as full 50 ml bottles in a new and very beautiful shape. I had barely managed to avoid buying the inkvent calendar, but buying a few of these bottles I couldn't resist.

Jack Frost is a medium blue color with heavy shading, some subtle silver sheen and heavy purple/red sheen. Any nib medium and up will clearly bring out the sheen. The color itself reminds me of a bright, cold winter day. I wouldn't use it in the office, but it is not wildly inappropriate.

The ink behaves really well. There is no feathering on this paper, high shading, a lot of sheen, and some shimmer as mentioned. The Splatter makes it visible. Jack Frost is not too wet but has average drying times, writes smooth enough and with negligible show-through. The ink probably likes ice more than water, it immediately smears, even days after writing. 
For this review I used ClaireFontaine paper. 

The color itself reminded me of a dark Kyanite du Nepal (Herbin) or Kon Peki (Iroshizuku). Sumor (Sailor Manyo) is a lot lighter. 

There is one thing about the bottle(s) that should be mentioned. The caps are virtually impossible to screw back on straight. They have the propensity to cross thread. Not just on this bottle but on the other two colors I bought as well. A pity.

All in all this is a very beautiful color. Highly recommended!

  It's Spring, we just had King's day and the European Championships football are being held next month. More than enough reasons to fill up some pens with orange inks. I was surprised to see I had gathered eight inks in the past few years that qualify as orange. Some true bright orange, some leaning more towards red or brown. Which one is your favorite?

Kikyou, Sailor Manyo

A few months ago this new ink series by Sailor was announced. Based on flowers, in a stylish 50ml bottle. What I see is not a flower, but an ink that is stormy blue with a hint of green. Teal? Maybe, but in my opinion it's darker than that, scans and monitors can be slightly deceiving. This ink can be a work horse. Very suitable for note taking, definitely works in the office, but also for personal notes and correspondence. The ink writes like a dream. It's not very wet, but smooth and extremely well-behaved in any pen. Just the combination crown mill vellum paper and a poster nib (as you can see), leads to some feathering of the ink. Drying times are simply fast, with just 12 seconds on this paper! Shading is low. Water resistance is low. Even after days it smears easily with just a tiny drop of water. I called this ink a work horse. It is, and an expensive one. Even though it's wonderful ink, it's simply not special enough to justify the price. Yonaga (Sailor)

Ultra violet shimmer ink, Manuscript

A new caligraphy ink by Manuscript with extreme shimmer. Definitely not something to use in the office but it looked interesting to write some cards with in the upcoming holiday season. This ink is clearly not meant for long notes or letters. A very dark violet or purple with heavy gold shimmer. I find it a hard to use ink. OK to use in a fountain pen like the TWSBI ECO with a stub nib, but a dip pen made the ink feather and spread, even on Clairefontaine or Crown Mill Vellum paper. On Lalo Vergé it was much better. The ink is very wet, causing considerable show-through and even some bleed-through. The drying time wasn't too bad though with 35 seconds. The shimmer smears easily for a bit longer. As can be seen even on this scan, shimmer is gold and very high. A bit of water will keep the ink readable, enough to rewrite. The violet or purple is comparable to Herbin's Améthyste de l'Oural . Diamine's Imperial Purple (no shimmer) is brighter and lighter.
