I won't add much to previous fantastic reviews of this ink, such as the ones here: http://www.fountainp...-faber-castell/
But I will add my subjective impressions of using this ink and some more scans and photographs.
Graf von Faber-Castell makes a luxury line of inks in beautiful, heavy glass bottles that will decorate any writing desk and will draw the eye. Despite the high price, the bottles contain 75ml of ink, so price per ml is actually reasonable. Considering other brands that sell in 20-30ml bottles for lower prices, but you get 2-3 times less ink. The packaging overall is top notch quality (personal note: I love the scent of the thick paper the box is made with, or maybe it's the ink used to print the graphics on the box).
In my experience with 10 colors of GvFC ink, all are a varying degree of low lubrication and dryness. Some might be "liquidy" coming off the nib, but the overall ink flow will not be high. Colors like Moss Green, Cobalt Blue, and Hazelnut Brown are more saturated and a bit more lubricated. Deep Sea Green and Gulf Blue have little to no lubrication and are very dry, and so they benefit from juicy pens with smooth nibs. Or else you will feel every imperfection of your nib and texture of the paper you write on.
Recently I have come to appreciate dry inks for the look they can provide if they are made of different hues of constituent dyes. This is the same type of dry flow and lack of lubrication one might find with certain translucent, multi-hue Sailor Manyo, Sailor Ink Studio, Troublemaker, and other inks of that nature. I am guessing the lack of surfactants, low saturation, and low lubrication are necessary to achieve color separation within a line, because some dyes flow farther than others, thus separating into gradients.
Graf von Faber-Castell Gulf Blue is a multi-hue powder blue ink. It reminds me of blue hydrangea flowers, with areas of pale aqua-sky blue in dry areas and shifting to lavender in more saturated areas. It has a similar idea to Troublemaker Milky Ocean, but Milky Ocean is comparatively more purple-shifted and slightly more saturated. I highly recommend broad or cursive italic/stub nibs for this ink to get the most of the color gradient effect. The wetter your pen, the better, both for the smoother writing experience and for the ink to be more prominent on paper.
Here is a scan of a mini-review sheet, paper is ivory-toned Fabriano Bioprima 85g with 4mm dot grid:
Graf von Faber-Castell claims their inks are indelible. You can go back and forth about the ISO standard the brand uses, but in practical terms, the ink has some but low water resistance. The purplish line remains behind if you dab the wet writing with a paper towel quickly, and you might be able to read the original writing if the lines were thick enough, as you can see on the scan above (the grid lines are very faint compared to the cursive italic writing). The ink is pale to begin with, and the remaining lines are even more so.
