Platinum Blue Black Ink

[bokaba]

Platinum Blue Black (Iron Gall) in Platinum Prefounte (F) on Rhodia Dot Pad

 

 

Drying time: less than 5 seconds

 

Flow: medium to wet (though I find Platinum F nibs much broader than Pilot)

 

Shading: little with fine nib, but more with broad or italic nib

 

Lubricated: no

 

Feathering/bleed through: I have not extensively tested in this area, but I would suspect there is little feathering or bleed through as is the case for most iron gall inks

 

Waterproof: yes, iron gall (clean pen frequently and don't let it dry in the feed if you leave it for a long time)

 

Color: deep blue when wet, dries to blue/gray (similar to Salix; the iron gall content darkens over time and overtakes the blue dye)

 

Value: one of the more expensive Japanese inks at $20 per bottle

 

Bottle design: decent

 

Other notes: many of the Platinum blue black boxes are incorrectly marked pigmented ink per Goulet Pens, but they are not pigmented as stated on the bottle

I'm very fond of this ink - still prefer 4001 though!

Nice review. Thanks? Dunno. You're making me want to buy it and I already have too much ink. OK, yes, thanks anyway. You deserve them for your nice work.

Thank you for this review.

Platinum's Blue/Black was for a while the only Japanese iron-gall ink available.

It was the colour that attracted me to this document ink. Initially a mid-blue, Platinum Blue/Black turns a shade darker as it oxidizes, but does not turn as dark as other iron-gall blue/blacks on the market. Some i-g blue/blacks shift almost to a pure black (as Diamine Registrar's). I also appreciate that Platinum Blue/Black cleans easily out of my pens, even with just water. Also, the filling "thingy" inside the bottle actually works as designed.
