Robert Oster Purple Rock

[visvamitra]

Robert Oster is new player in fountain pen ink market. He operates through worldwide network of wholesalers. The inks are sold in 50 ml PET bottles with a tightly secure twist cap. I don't know who makes the inks for the shop, but the colors look interesting and fresh. At the moment Robert Oster inks are available in billion colors - I lost track how many.

Sample of Purple Rock was sent to me by Akszugor. I'm not thrilled bi yt. The ink feels dryish. The hue is ok, but the writing experience is far from amazing.

Nice, but more grey and less purple would have been even better.

Nice review. How does it compare to Kyo iro soft Snows of Ohara?

More gray, and it would have been Gray Rock. Perhaps a touch more purple. If it feels dryish, does that mean it's not saturated?

Seeing the full review, I think this is almost certainly what I had in my bottle labeled "Summer Storm". Yours seems slightly darker than mine, but that's easily explained by differences in pen and paper combinations.

 

I think this color is pretty attractive in large quantities, but a little lackluster in regular writing.

Nice review. How does it compare to Kyo iro soft Snows of Ohara?

 

Soft Snow of Ohara is wetter, has more blue, and, although not vivid, could never be called a gray. Purple Rock is a purplish gray that needs certain conditions for the purple to show.

 

Both inks are among my favorites, but Purple Rock has one characteristic that I find unsettling, which is that on certain papers it looks greenish, and on others actually green.

 

In a wet pen, I have found Purple Rock to be a dark gray, close to black. Soft Snow of Ohara in a wet pen is a very dark blurple.

Great review, Vis! I am not inspired by this color at all.

Has anyone experienced staining with this ink? It hasn't stained any of the converters in which I've used it, but I'm thinking of putting it in a Pelikan 140.

 

I know one is always warned against purple where staining is a concern, but despite its name, this ink is grayer than it is purple, and because it is on the dryer side, I thought it might be a good fit for the Pelikan.

Great review, does not seem like a color I would buy after seeing it.
